Balance AC

Is anyone else using Balance AC? It doesn't seem to be working in the UK, it hasn't shown any values for the last few days I've looked. I'm also not convinced it works the way it says it should, I've got 3 heat pump AC indoor units used for heating and there have been times when one is above the target temperature, one below and it turns the temperature down on the one that is low, leaving the one that is high. It also seems to work the same way as overriding the scheduled temperatures and this means the geolocation function doesn't work as intended so could end up costing more rather than saving money.
