I doubt it's related to the MySensors communication. Are you using a Dallas temp sensor? Could you check that the is actually connected to the dallas sensor by using isConnected().
When googling your problem I found a few hits on -196.6 which is the error code (DEVICE_DISCONNECTED) converted to Fahrenheit.
Start debug mode (Config.h) to see what the sensor actually sends.
the problem is "if (switch.state == 'On') then" that not works, write:
if (switch.active) then
or
if (switch.inActive) then
Device attributes and methods for all devices
Thanks everyone for the answers. However what I would like to do is create a routine with Dzvents that when I have the "red" indication (as shown in the image) causes a switch to operate which cuts the voltage to a device. The value of ".lastUpdate.minutesAgo" seems not to be the right solution because it continues to be increased in any case, regardless of the temperature value and the status of the "red" or normal indication.
