Ok sorry, I see the difference. I still use version 1.5.4

I don't think so.... but why should you or I? I get a switch command from the controller (Domoticz in my case) which is 'translated' to a newremoteswitch command to the 433 mhz transmitter. (Please feel free to let it go if I lack knowledge here and it is not helpfull for your problem :) )

I also use newremoteswitch for KlikaanKlikuit on a MySensors node and it works great... So your problem is probably indeed something else.

@Sander-Teunissen I have some rev6 that I am willing to sell. Let me know if you are interested.

@tbowmo how did you finally manage to install Grafana on the RPI?
Some time ago I tried to do the same on the Domoticz image but gave it up...

@sundberg84 thanks for the nice design!
I was not really aware of 'official' and 'unofficial' version (and version at all..) so just after the post of ar91 I followed the link to dirtypcbs and ordered 10 Rev6 boards. I will share my experiences here as soon as they arrive and see if it is worth while to order the rev8's. I like it that it is even smaller withour loosing functionality.
