Hi,
I’m always getting an error after restart of pimatic.
error [pimatic,VariablesDevice]: Error getting attribute value sonnensensor.ds18b20-differenz: Expected variable espeasy-sonne_mqtt.espeasy-sonne-temp_high to have a numeric value.
It comes from a calculation which is not possible immediately after startup of pimatic. The necessary values are “unknown” (string) before they becomes updated with the detected temperature (number) of a ESPeasy device. Is it possible to handle this somehow?
I think it could work when the status “unknown” would be replaced by “0” when the variable type is a “number”.
This is the config of the affected VariablesDevice:
