I have a flow that regulates by heating with a heatpump. For this I need the outside temperature. At this moment i use the temperature from Homey’s Weather (add them up and divide by two) and from the KNMI App, but they sumtmes differ from the actual outside temperature. My plan is to put 2 Sonoff…

Hello, I have made an advances flow to do as you said. Every time the temperature changé it restart a 24h timer. And every day at 20h00 the flow is checking every timers are still running. If no an alert is raised for the concerned sensor.

Spounds good, I’m not to familiar with the extended options of Device Capabilities though, only the regular ‘create virtual device’…
