It shows wrong hot water temperature all the time. Also when I'm checking consumption from any day of previous months and after that want to check one day before I need again scroll again from today. No option to export consumption. Wrote in the app couple of times - no answer.

This app us getting worse every day. It still remains in the shadows of the previous Smart Tc app and lacks both its user friendliness and functionality. Recently, it makes you log in every other week, which undermines the use of strong passwords. Settings of the boiler can still not/no longer be configured through the app. This, together with the lack of real smart-home integrations (note to BDR: Alexa is _not_ the definition of smart home) makes a BDR boiler a thing of the 20th century.
