Signal K Govee Plugin

Description

The Signal K Govee Plugin reads temperature, humidity, and battery level data from Govee H5179 devices and sends it to the Signal K server. It is untested with other Govee devices.

Installation

The plugin can be easily installed via the Signal K Appstore. Simply search for "Signal K Govee Plugin" and follow the installation instructions.

Configuration

Once installed, you need to configure the plugin to connect to your Govee device.

1. Open the Signal K server settings:

   • Navigate to your Signal K server's web interface.
   • Go to the "Plugins" section.

2. Locate the Govee Plugin:

   • Find "Signal K Govee Plugin" in the list of installed plugins.

3. Configure the plugin:

   • Govee Device Address: Enter the MAC address of your Govee H5179 device. This is usually found on the device or in the device’s documentation.
   • Polling Interval: Set how often (in seconds) the plugin should check the Govee device for new data. The default is 10 seconds.

4. Save the settings:

   • Click the "Save" button to apply your settings.

Bluetooth Configuration

To enable Bluetooth scanning, you may need to configure the permissions on your device. The following is tested on a raspberry pi 4 running openplotter:

1. Set the necessary permissions:

   sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

2. Ensure permissions are set on startup:

   • Add the above command to /etc/rc.local to make sure permissions are given on start up.

Usage

Once configured, the plugin will automatically start scanning for the specified Govee device and send data to the Signal K server.

You can monitor the following data paths in Signal K:

• Temperature: environment.inside.temperature (in Kelvin)
• Humidity: environment.inside.humidity (as a fraction from 0 to 1)
• Battery Level: electrical.batteries.govee.batteryLevel (as a fraction from 0 to 1)

Example Data

Here is an example of the data that will be sent to your Signal K server:

{
  "environment": {
    "inside": {
      "temperature": 297.15
    }
  },
  "environment": {
    "inside": {
      "humidity": 0.45
    }
  },
  "electrical": {
    "batteries": {
      "govee": {
        "batteryLevel": 0.80
      }
    }
  }
}

Troubleshooting

• Make sure your Govee device is turned on and within range of your Signal K server.
• Double-check the MAC address entered in the configuration.
• Check the Signal K server logs for any error messages or debugging information.
