This is a good little app. If I had a criticism, it is the fact that the conflict between manual settings, the app and scheduled settings is messy. If you set the heater using the manual remote then it is difficult to work out when the schedule takes over or if you manually set via the app again it is confusing, and it is not clear which method is in control of the heater. I would like to see an indicator (or color) for each of the modes of operation so that you can switch between modes easily.

I've been using the Onecta app now for over 2 years, I have 2 AC units and 1 air purifier that's controlled by it. It's really very good and I love it, being able to control everything remotely is just fantastic, and can also save you money if you accidentally leave something switching on. Just log on the app and check everything

It keeps failing to recognize my heat pump. And won't let me add it. And now its temperature display continually lags well behind the display on the Daikin unit.

Very poor experience. - I have to kill and start the app every time, otherwise it cannot connect to the server. - I'm using it to control and monitor my Althea 3 heat pump - it provides only the basics - setting flow temperature, simplified energy usage - Cannot read energy usage in 1h intervals, only 2h and more than last 2 weeks I would have used different heat pump maker if I knew this application before
