I am testing a nodemcu lilo v3 board and its working fine by now.
When I power off the nodemcu board, domoticz stays displaying the last value. I was hoping it will go to zero or something. Is there somehow to manipulate this?
It is switching a dummy switch between different values of lux.
Because he is runnig now on power bank, and it wont last for ever

Actually I have it now very stable, presence detection with lux meter is switching on and off @ the right moments.
All done with blockly only. I someone want to know how, I will post it somewhere on this forum.
