Evohome: using a dummy switch to control thermostat
Posted: Thursday 04 October 2018 15:55
I have a Honeywell Round Connected thermostat, which can be controlled via EvoHome (mytotalconnectcomfort.com). I've installed the Honeywell EvoHome hardware in Domoticz, using the Web API-option. This works, and a Temperature device is created which shows the current room temperature and the setpoint.
However, for usability reasons (and WAF) I want a dummy switch so I can manually control the thermostat setpoint from the Android app.
I've created a dummy switch, and use the following script:
Running the script shows no errors, and indeed, the setpoint of the thermostat device is changed to the set value of the dummy switch. However, within a minute this value is overwritten by the previous value.
I'm not even sure if the actual setpoint is changed on the thermostat itself, or if it's only in Domoticz where it's changed. It looks like the set values by the script are overwritten by the values from the Honeywell-servers.
How can I resolve this in a proper way?
