Node-red-contrib-evohome NPM

node-red-contrib-evohome

This provides nodes for controlling Honeywell Evohome. It's using the unofficial API to interact with the evohome servers. node-red-contrib-evohome delivers 3 nodes:

Evohome Config

Evohome Config is a config node to set the userid and password to login to evohome servers.

Evohome Status

Evohome Status periodically polls the status of evohome servers. The interval in seconds can be set. To disable periodically polling, just set interval to 0 (zero). You might manually poll date via input message. Note: The first poll creates session only, there is no data fetching on first poll.

Evohome Status returns the zone-id, the name of the zone, the temperature, and the cuttent setpoint value. It will send a message per thermostat. The msg.payload looks like:

{ id: "1234567", name: "bedroom", currentTemperature: 22, targetTemperature: 22, systemModeStatus: { mode: "Auto", isPermanent: true } }

Evohome Control

Evohome Control makes it possible to set the setpoint per thermostat. It offers 4 ways to do so:

only provide the zone id will make the thermostat revert back to the schedule.
zone id and temperature will set the temperature until next schedule.
zone id, temperature and time will set a temporary setpoint until the given time, then revert back to the schedule.
zone id, temperature and permanent-flag will set the temperature permanently. The msg.payload looks like:

{ id: "1234567", temperature: 22, endtime: "22:00:00" }

{ id: "1234567", temperature: 22, permanent: true }
