Can anyone see any apparent flaws with the attached piston?
Problem:
If mode set to away, the sensibo will set correct temperature, but keeps on sending the commands for temp, fanspeed and fan swing over and over…Same if mode is home, it sets the correct temp/fan for the given timeperiodes, but keeps on looping the command 
Webcore has their own forum now, and most of their experts hang out there. So you will probably get the fastest answer if you ask your piston questions there. 
Could add a check of the heating point to only execute if the heating point isn’t already at the correct temperature; i.e.
If Location mode is Away
and
heating point not equal 16 C
