[bug] - Keep_alive not working

[HappyPlotter]

I have set the thermostat with keep_alive to control a shelly device. On the shelly I have set a timeout of 10 minutes and the keep_alive is set to 1 minute. The shelly device turns off after 10 minutes and then immediately turns on again. It seems like the keep_alive is not working which makes the heater cycle every 10 minutes
