App takes ages to open and load. sometimes the app doesn't work.
I bought a Viesmann boiler and Temperature sensor. I added the boiler, but the sensor is not available to be added (not an option). @Developer...the professional person that came to start the device was not able to do it. A way for a direct contact would be great
I would rate it (minus 10 stars) even one star is a high rating. I am a user of the "BOKA32" device and I do not have an external thermostat.. . And I don't accept the excuse that I have to have an external thermostat.. It's unbelievable that nowadays the application doesn't have time control of turning the device on and off throughout the day.. I have no words..
complicated system, would not have this system again. Heating and hot water work perfectly fine, it's just if you want to put Heating on for a short period of time
Very good.
works well
