I’m using the script from @thetrueavatar to monitor and control my heating system.
After some changes on the server side by Viessmann I noticed the external temperature isn’t reported in 0.1C steps anymore. Since Apr’28 00:30 I am getting values only like 10.5, 11.5C etc., no full degree and no other fractions. Sounds odd to me.
Does anybody else observe the same?
I asked on the Viessmann Expert forum, however I won’t bet on a (usefull) answer that way.
