Grohe Sense Node

The node is able to get the status of a Grohe Sense, Grohe Plus or Grohe Guard node.

Sense

To get the status simply send any msg.payload to the input.

See the example flow sense in the examples folder.

Sense Guard

To get the status simply send any msg.payload to the input. To send a command to open the valve you need to send the following message:

msg.payload = {  
    command : {
        valve_open: true,
    }
};

See the example flow sense guard in the examples folder.

Getting Historical Data

To read out the internal measurement history you need to specify the start and end data as follows:

let end = new Date();
let start = new Date();
start.setDate(end.getDate() - 2); // last 2 days.

msg.payload = {  
    data : {
        from : start,
		to : end,
		groupBy : 'hour' // or 'day', 'week', ...
    }
};

Date can be passed in milliseconds format, too: e.g. Date.now

let now = Date.now();
let end = now;
let start = now - 24 * 60 * 60000;

msg.payload = {
    data : {
        from : start,
        to : end,
		groupBy : 'hour' // or 'day', 'week', ...
    }
}
