@leader21 Sure, I’ll keep you updated.
First finding: there are no wheels on the ITL-1000 for coding the receiver. But the manual reads “all radio transmitters of intertechno are suitable for switching”, so I’ll try with a free choice code from this table. Given, that roughly 16.7 million codes are possible, maybe the house and unit ID can be just increased to up to 4096? Needs to be tested ^^
It will take some time, because my RaspberryPi is still in another apartment than the walls where the switches will be mounted. Additionally I’m on a business trip for the next 2.5 weeks. (one of the reasons the light should be switched off automatically when I’m not home )
