The temp/humi values are obtained by executing a script. For OH to be able to call a script the “Exec” binding had to be installed. Can you make sure this is installed and functioning ok?
I also remember there was an extra security need that each script had to be included in a whitelist but this should not be needed anymore (HestaPi stuck at 0°-screen (no. 15 of First boot ONE-tutorial) - #16 by rlkoshak).
