General

To check if the node is available in the network, a HTTP GET to /shelly is issued. This route returns a type string which is verified. You can configure an interval for the polling. The default is 5000ms, 0 is off = no polling. Most nodes will call HTTP GET to the /status route after a input is received from the node. This answer is directly available at the output via msg.status. The msg.payload property contains a lightweight version of this status object. The hostname can be left empty in the configuration node. This deactivates polling, too. In this case you must pass the hostname in the msg.payload.hostname. This can be useful, if you want to use one node for several devices or if you want to make use of sub flows. (username and password can be passed in msg.payload, too)

{
    hostname : '192.168.178.250'
    username : 'user'
    password : 'password'
	...
}

callback mode vs polling mode

Unlike generation 2 devices which support scripts the older generation 1 supports only webhooks which are very limited. You can always use polling mode, but some devices like sensors and buttons often sleep to safe energy. In this state the node can not reach the shelly in the local network. This results in a polling error which is not a problem, but often generates confusion when the user sees error messages in the node-red debugger or console. To avoid this you can try to enable callback mode. In callback mode a webhook is configured to the shelly which notifies to the node when sensor data changed. The node needs to open a network port to be able to receive these messages. You must configure this network port, make sure that it is not already in use. If node-red runs inside a docker container or any other bridged network then you should also configure the hostname under that the shelly device can reach the node-red server (Leave this field empty if you run inside the same network segment). The node retries to set the webhook if the device is sleeping as long as it succeeds. As soon as the status shows "Connected" the webhook is set. Note that gen2+ devices that have bluetooth support can act as a bluetooth gateway for shelly BLU devices. To activate that feature you must use callback node and check the bluetooth checkbox.

Shelly Node (Generation 1)

See also https://shelly-api-docs.shelly.cloud/gen1/#shelly-family-overview The node can communicate with several shelly types. You must select the correct device type from the combobox when configuring the node. Devices are grouped as follows:

Settings

You can configure your shelly from within the web interface. But there is also the possibility to change the settings from with a flow. Simply pass one or more settings objects in msg.settings:

[
{
    device : 'ext_temperature',
    index : 0, 
    attribute : 'overtemp_threshold_tC',
    value : 90
},
{
    device : 'ext_temperature',
    index : 0, 
    attribute : 'overtemp_act',
    value : 'relay_on'
}
...
]

To understand the properties please have a look at: https://shelly-api-docs.shelly.cloud/gen1/#shelly1-1pm-settings-ext_temperature-index It always follows the same scheme "/settings//?="

Relays (Shelly 1, 2, 1PM, 1L, Plug, PlugS, Uni)

The node is able to turn on and turn off a shelly switch. It outputs the status of all relays after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The relay number is optional and defaults to 0. Note that the UNI can also deliver the ADCS values in the status.

{
    relay : 0,
	timer : 1,
	on : true
}

or you can make use of the alternative notation:

{
    relay : 0,
	timer : 1,
	turn : 'toggle'
}

turn can be one of the following: 'toggle', 'on', 'off' timer is optional flip back timer in seconds

Right after having sent the request to the shelly device a status request is done. The relays property of the response is output on output 1.

If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

The output of the node is an array of status objects for every relay of the switch:

relays : [
    {
        ison : true,
	    ...
    },
    {
        ison : true,
	    ...
    },
],
meters : [
],
inputs : [
],
adcs : [

    {
        ison : true,
	    ...
    },
    {
        ison : true,
	    ...
    },
],
meters : [
],

Download of historical data

Devices like the EM and EM3 store data. You can download the historical time series data as follows:

[
    {
        download : [0, 1, 2],
	    ...
    },
]

The download variable contains a list of channels that should be downloaded. This can be either one or more numbers. Note that downloading from the device can take some seconds as it depends on the size of the gathered data. Data is sent to output 2.

Examples

shelly EM flow
shelly EM download CSV flow

Roller Shutter (Shelly 2, Shelly 2.5)

A node that controls a shelly roller shutter device (Shelly 2.5). The relay number is optional and defaults to 0. The following object for open or close the roller shutter:

{
    roller : 0,

{
    roller : 0,
	go : 'close'
}

{
    roller : 0,
	go : 'to_pos',
	roller_pos: 50
}

If device is in relay mode: Turning on is done by sending the following payload into the input. The relay number is optional and defaults to 0.

{
    relay : 0,
	on : true
}

or you can make use of the alternative notation:

{

The output of the node is an array of status objects for every roller and every relay of the roller shutter:

{
rollers : [
        {
            state : 'open',
			current_pos: 50,
	        ...
        },
    ],
relays : [
        {
		    ison : true,
			...
		},
	],
meters : [
]

Examples:

shelly roller3 flow

Dimmer (Shelly Dimmer 1/2, Shelly Bulb Duo, Vintage)

The node is able to turn on and turn off a shelly dimmer or shelly bulb duo and set its brightness. It outputs the status of all lights after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The light number is optional and defaults to 0. The brightness can be set between 0 and 100.

{
    light : 0, // default = 0 (not needed for bulb duo)
    on : true,
    brightness: 100,
	white: 100, // for bulb duo
	temp : 2700, // for bulb duo (same as white but in K 2700 - 6500)
	transition : 0 // for bulb duo (0..5000ms),
	timer : 1, // flip back timer in seconds,
	dim : 'up', // up, down, stop
	step : 10, // dim step in %
}

Like in the switch node you can replace on with turn and choose a value from the following: 'toggle', 'on', 'off'

You can also control the shelly state and brightness independently.

{
on: true
}

and

{
brightness: 100
}

Right after having sent the request to the shelly device a status request is done. The relays property of the response is output on output 1.
This feature can optionally be disabled by unticking the status checkbox in the node configuration options.

If you only want to get the current status of the dimmer without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

lights : [
    {
        ison : true,
		brightness: 100
	    ...
    },
    {
        ison : true,
		brightness: 100
	    ...
    },
],
meters : [
]

Examples:

shelly dimmer flow
shelly bulb duo flow

Thermostat (Shelly TRV)

{
    position : 0..100, // 0 = closed
	temperature : 4..31, // target temperature in C
    schedule : true,
	scheduleProfile : 1..5,
	boostMinutes : 0..n
}

Right after having sent the request to the shelly device a status request is done. The thermostats property of the response is output on output 1.
This feature can optionally be disabled by unticking the status checkbox in the node configuration options.

If you only want to get the current status of the TRV leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

Examples:

shelly TRV flow

RGBW (Shelly RGBW2, Shelly Bulb RGWB)

The node is able to control a RGBW LED light strip or a bulb RGBW.

If you only want to get the current status of the node without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

The node accepts the following input

{
    red : 0,
    green : 0,
	blue : 0,
	white : 0,
	temp : 5000, // bulb
	gain : 0,
	brightness : 0, // bulb
	effect : 1,
	on : true,
	timer : 0,
	transition : 0, // bulb
}

red, green, blue, white can be between 0 and 255. gain can be a value between 0 and 100. brightness can be a value between 0 and 100. effect = 0 means no effect. timer can be a value in seconds to flip back on/off transition can be a value in milliseconds between 0 and 5000 temp can be a value in K between 3000 and 6500 for white

lights : [
	{

Sensor (Shelly Window/Door Node 1/2, Shelly Flood, Shelly H&T, Shelly Motion 1/2 )

The node is able to poll a shelly window/door, motion, gas, ... sensor. It outputs the sensor status together with battery and sensor values on every change sensor status. Note that some sensors sleep when nothing is detected and is thus not accessible via REST.

The output of the window, door sensor is as follows:

{
    sensor
	{
		state: 'close',
		is_valid: true
	},

	lux
	{
		value: 150,
		illumination: 'twilight',
		is_valid: true
	},

	bat
	{
		value: 100,
		voltage: 6.01
	}
}

The output of the motion sensor is as follows:

{
    sensor
	{
		motion: true,
		vibration: true,
		timestamp: 12345,
		active: true,
		is_valid: true
	},

	lux
	{
		value: 150,
		illumination: 'twilight',
		is_valid: true
	},

	bat
	{
		value: 100,
		voltage: 6.01
	}
}

Examples:

shelly door flow
shelly motion flow

Button (Shelly Button, I3)

The node is able to control a shelly button. It outputs the status of all inputs after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The input number defaults to 0.

{
    input : 0,
	event : 'S'
}

Event can be one of the following S=short push, SS=double short push, SSS=triple short push, L=long push (and LS=long short and SL=short long for the I3). Right after having sent the request to the shelly device a status request is done. The inputs property of the response is output on output 1.

If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

The output of the node is an array of status objects for every relay of the switch:

[
]

Note that the button is not always reachable as it falls to sleep. This is not the case for the I3.

Examples:

shelly button flow

Shelly Node (Generation 2 and Generation 3)

See also https://shelly-api-docs.shelly.cloud/gen2/ See also https://shelly-api-docs.shelly.cloud/gen2/Devices/ShellyPlus1PM The node can communicate with several shelly types. You must select the correct device type from the combobox when configuring the node. The msg.payload property can be used to issue commands (see examples below). Note that you can send multiple commands at once by creating an array in msg.payload.

callback mode vs polling mode

Unlike generation 1 devices the new generation supports the usage of scripts. In polling mode the node just behaves like the generation 1 node. In callback mode a script is uploaded to the shelly which sends all notification events to the node. The node needs to open a network port to be able to receive these messages. You must configure this network port, make sure that it is not already in use. If node-red runs inside a docker container or any other bridged network then you should also configure the hostname under that the shelly device can reach the node-red server (Leave this field empty if you run inside the same network segment).

Relay (Plus 1, Plus 1 PM, Plus 2 PM, Plus UNI, Pro 1, Pro 1 PM, Pro 2, Pro 2 PM, Pro 4 PM, Plug US, Mini, 1PM Mini, PM Mini, Shelly Wall Display)

The node is able to turn on and turn off a shelly switch. It outputs the status after every interaction with the shelly device. Turning on is done by sending the following payload into the input. The relay number is optional and defaults to 0.

{
    method : 'Switch.Set'
	parameters : {
        id : 0,
        on : true,
        toggle_after : 2 // optional flip back time in seconds
    }
}

or you can make use of the alternative toggle command:

{
    method : 'Switch.Toggle'
	...
}

Note that toggle_after is optional. The unit is seconds. Right after having sent the request to the shelly device a status request is done.

If you only want to get the current status of the switch without turning on or off you should leave the msg.payload blank. This is useful, when you want to poll for the status cyclically.

The output of the node is the full status object of the device. See https://shelly-api-docs.shelly.cloud/gen2/Overview/CommonServices/Shelly

Button (Shelly Plus I4)

The node is able to control a shelly button. It outputs the status of all inputs after every interaction with the shelly device. See https://shelly-api-docs.shelly.cloud/gen2/Components/FunctionalComponents/Input

The output of the node is an array of status objects for every relay of the switch:

[
]

Examples:

shelly button plus flow

Sensor (Shelly Plus H&T, Plus Smoke)

The node is able to control a shelly sensor. Usually sensors sleep all the time to save energy. Hence you will get an error when polling for the status but sometimes when the device wakes up you will receive valid data. Another possibility is to use the callback mode. Unlike other 2. generation devices sensors do often not support scripts. Therefore webhooks are installed as soon as the device is not sleeping. When the shelly calls the webhook, the node gets the status and sends it to the output. You can wake up your device manually on redeploy to speed up initialization. Otherwise errors will be generated in the debugging pane telling you that installation of the webhook failed.

BLU Gateway (Shelly BLU Gateway)

The node is able to control a shelly BLU gateway. This node should be only used with callback mode and event output. It uploads two scripts: one for the callback like in all other gen 2 devices and one that scans for bluetooth signals. This script was taken from https://github.com/ALLTERCO/shelly-script-examples/blob/main/ble-shelly-blu.js and is licensed under the apache 2.0 license!

The output of the node is an event object. Bluetooth event objects have the event name "shelly-blu".

msg.payload.info.event === "shelly-blu"

You can take the mac-address to find out what BLU device sent the messages:

msg.payload.info.data.address

Examples:

shelly BLU gateways flow

Some notes about BLU Support

Almost all gen2+ device support bluetooth and can be used as blu gateway by using callback mode and activating the gateway support in the config node. Messages from the BLU devices are in BTHomeV2 format: https://bthome.io/format/

BLU RC Button 4

The node is able to control a shelly RC button 4. This device communicates via bluetooth. You must use at least one shelly as bluetooth gateway to be able to receive message in node-red from that device. This gateway node should be only used with callback mode and event output. It uploads two scripts: one for the callback like in all other gen 2 devices and one that scans for bluetooth signals. This script was taken from https://github.com/ALLTERCO/shelly-script-examples/blob/main/ble-shelly-blu.js and is licensed under the apache 2.0 license!

The output of the node is an event object. Bluetooth event objects have the event name "shelly-blu".

BLU devices contain a detailed description about the types that are used: E.g. the documenation for the shelly RC button 4 can be found here: https://shelly-api-docs.shelly.cloud/docs-ble/Devices/wall_us/ Type 0x3A is tranmitted if a button is pressed. The value can be on of the following: 0x00 - none (button not pressed) 0x01 - press 0x02 - double press 0x03 - triple press 0x04 - long press 0xFE - hold The buttons are transmitted as an array with the values mentioned above.

msg.payload.info.event === "shelly-blu"

You can take the mac-address to find out what BLU device sent the messages:

msg.payload.info.data.address

Examples:

shelly BLU RC button 4 flow

Shelly REST API

For a complete documentation see also https://shelly-api-docs.shelly.cloud/#common-http-api

Shelly Cloud API

See also https://shelly-api-docs.shelly.cloud/cloud-control-api/communication The node can communicate with your shellies via cloud API. You need to create an authentication key in your shelly app and enter it into the config node. All devices have unique IDs. You can configure the ID in the config node or send it into the node, just as you prefer. Note that the cloud API is limited to 1 call per second. If you call too fast you will likely receive an error 401. You can get the status of a device by simply triggering the node using a msg.payload as follows contains the id of the device

{
	type : 'status',
    id : 'your device id here in hex',
}

Listing all devices

Similar to retrieving the status of a device, you can retrieve the status of all devices by changing the type to "status_all" and removing the "id" line:

{
	type : 'status_all'
}

Relay

You can control relays as follows:

{
    type : 'relay',
    id : 'your device id here in hex',
	channel : 0,
	turn : on | off
}

Examples

shelly cloud flow

Roller

You can control rollers as follows:

{
    type : 'roller',
    id : 'your device id here in hex',
	direction : open | close | stop
	pos : 0..100
}

Please use direction or pos here.

Examples

shelly cloud flow

Light

You can control lights as follows:

{
    type : 'light',
    id : 'your device id here in hex',
	channel : 0,
	turn : on | off
	
	white : 0..255
	red : 0..255
	green : 0..255
	blue : 0..255
	gain : 0..255
	brightness : 0..255
}

Please see documentation. It depends on if you have RGBW or White lights.

Examples

shelly cloud flow

Bulk Control

You can turn on|off many relays or rollers with one single call as follows:

{
    type : 'relays',
    turn : on | off,
	devices : [
		{
		  id : 'your device id here in hex'
		  channel : 0
		},
		{
		    ...
		}
	]
}
