A return to higher score after the time picker bug has been fixed. Overall a good app with lots of info about the boiler. Would prefer if the outside temperature measure was clearly displayed alongside the indoors one (not sure if it's that or general weather data that is shown on home page, it's unclear). More troubleshooting & error diagnostic info would be helpful. Sep 2022: Noticed a bug, app won't let you change between DHW Eco & Comfort mode, but this has now been fixed, thanks.

I don't know why, but the ViCare app when used with a ViCare Indoor Temperature Sensor on a Viessmann 100W System Boiler has limited functionality. There is no option to set multiple times for hot water and no option to edit the heating curve. Using the ViGuide commission app presents all of those options, but ViCare does not! What is going on Viessmann, has this combination even been tested?

Decent enough to control generally, I just can't figure out how to connect the wireless thermostat even though the instructions point you toward this app. Changed to 5 stars because, quite frankly, their support to my original query was excellent. Responded within hours.
