Hi Martin,

@martinhjelmare
I've been trying the last couple of days to get it working, but to no avail...

I stell get errors like

ValueError: need more than 1 value to unpack

The number can change though.
I've tried your suggestions, updated and rebooted the pi but still no luck.
Uninstalled and reinstalled home assistant but that also didn't help.

Any other things I could try?

I just received my order from Dirtypcbs. The protopack I ordered had 11 boards, so that's nice.
They took 10 days to arrive in Belgium.
From first glance, it looks like they's work, but I'll have to test it this weekend to be sure.
Here's a picture.

Great, thanks.

The sketch now works as it should.
Below is the finished sketch.
I also added a counter so that after 10 consecutive interrupts from the motion sensor, the temp and hum get read and transmited. (motion-on generates an interrupt and motion-off generates an interrupt, so it's actually 5 motion triggers)
Otherwise if there is a lot of movement during a certain timeframe (mornings), hum and temp won't be measured.

Later I will edit the sketch to have all transmits together to save more battery power.

Here's the sketch:

 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.
