My system has only 2 androids phones. Location on. Thermostat sense of. Scheduled 8am 22 degree's, off 23 pm. Eco shows after 2300. My problem is. Both phones in house. And heating. All by itself turns to eco. Just now and again. Sometimes it works OK ie. One phone leaves, system stays on.both phones away, sets to away, and sometimes does not turn on. Other times it works, all problems intermittent. WiFi all with small bungalow, 3-4 metres from router, Thermostat. Boiler. WiFi good.so why does it not as programmed, seems it goes to sleep and sets up different from my simple setup
