glad I’m not alone here @DavidZH did you see any errors in the log?
Today I will switch my pimatic installation form RPi1 to RPi2, what kind of Pi’s are you using?
Maybe @Icesory can help to troubleshoot this!? I found a closed issue that describes the issue https://github.com/pimatic/pimatic-homeduino/issues/11
The messages postet above are gone when the BT dongle is not plugged in but the timeout errror is still there,
A short time (maybe 2 min) after restarting pimatic, the switches are “switchable” but nothing happens on the sockets.
