The app is ok but Cosy is as bad as it gets in terms of a smart thermostat. The temp readings are either completely wrong or I am unable to tell the difference between what is cold or hot anymore. I simply use it as a slightly more convenient timer. Will invest in nest soon.
Have had cosy for 2 years. Added hot water switch 6 months ago. Had to re-pair and reset a few times, sometimes with the excellent and courteous help of customer support. It's a great system, but people, really! Give the company a chance. It's innovative so there will be issues, and their system is sometimes thwarted by other systems it has to work with. It's a learning curve for me too, but I wouldn't be without cosy now and unlike some of their competitors there is no expensive monthly charge to run it! Keep up the great support GEO !
App has been great until this week when despite, switch, hub and thermostat display being on the app won't connect. I can put into hibernate and back out and it changes the cosy display but the app says that it's unable to make the change. I'm unable to change profiles from the app at all
As for the over-temperature issue, I've found that when the thermostat is away from the hub it records (almost) correct temperatures. The cradle/hub itself generates heat when the thermostat is docked (take the thermostat off the hub after a charge and feel the connection point to see what I mean) so could this be the cause of inaccurate/too hot readings?
Works mostly as expected. However, information on the Activity screen is always incorrect, showing "slumber" regardless of setting change via hub, app or schedule. History graph has similar problem, always showing blue "slumber" although the actual temperature trace seems accurate. Please allow zoom or ability to set graph range. 0-30C range virtually shows straight line...
Well 2 years on still poor service from geo, waited 115 hours for cosy to enable alexa skills. They said it shouldnt take any longer than 48 hours and servers would do this automatically. This is way too long. There are no smart devices created ie. Cosy, slumber comfy, heating on. This would have made it possible to add cosy into alexa routines making it possible to set user defined phrases to call the heating. Would be more stars if alexa was better intergrated but I have come to expect a poorly though out implmentation from cosy. One day they will start listening. Graph shows only slumber and past activity is only showing slumber as well.
We have some super Cosy updates in the pipeline for you – like our new temperature graphs (more info below). But, to gain access to them you’ll need to update to the newest version of this app first. Go on, download it today! We wouldn’t want you to miss out.
