Very expensive thermostat/gateway combo with an app that isn't even "smart". Where to set "away temperature"?! Now it defaults to 15 deg. Celsius and no option to change that like in the sensoapp. And no explanation if this is only for heating or heating+water. Time can only set in blocks of 10 min. Make that 5 min. Also for time setting for temporarily change. And maybe even change the function to which time you want to have the change, instead for how many time the change must be active.

Getting better but improvements still needed: error messages from boiler are opaque and unhelpful (why not say 'your boiler's annual maintenance is due'?); nice to have the heat curve settings in the app, but the visual plot should be based on your target temp - we use 19.5C, not 21C - add as a selectable plotting option in the HC settings?; need ability to be able to save several weekly planner heating programmes rather than only having one.

Essentially useless. I have reinstalled, rebooted the gateway and it still takes 3-5 minutes to log in, requires force closure and requests sign in every time. Even then it transmits the instruction to the system about once in every five attempts. Great if you want to see the temperature, useless for control of the system. I have tried reinstalling, clearing cache and data, even rebooting my entire ashp system. Suggest the developers go and ask Hive or Nest for a few pointers.
