I have a Harman P43 and was wondering if there was an alternative to that ridiculous room temperature sensor, which, by the way, I am on my second one in five years? I Harman makes one, nonetheless it's expensive and Sky something-or-another makes some but which model? There's some threads here however I am looking for current information, these threads are several years old. It need not be fancy, programmable model, I just was something akin to a simple wall mount thermostat. What do you folks use?
