might also be an issue with my Max! setup - when I toggle to eco/comfy it also doesn’t work. The error is “error [pimatic]: Command was rejected”. Not sure if it worked before your changes.
EDIT: Setting the temperature also doesn’t work, same error message. Reading the temperature from the wall thermostats seems to work fine.
EDIT2: OK, for some thermostats it seems to work - from time to time. So the error occurs for some all the time for others not. I was thinking an unstable connection could be the issue but the one that doesn’t work is next to the cube… regardless of the issue I have I think the echo plugin needs to handle the error to avoid crashing pimatic.
