Well, turns out it was defective hardware... I replaced both the arduino and the comm module and all works well!

Hello all,

I recently moved my outside temp/humidity sensor from the front of the house to the back and noticed that the radio is not strong enough to go through the whole house from the new location so I created a repeater node which I placed inside the house literally just in front of the outside sensor, just with the wall in between.

When I boot the repeater node, I can see it present itself to the gw, but the only way for me to see the sensor node is to boot it from within the gw range.

I have forced the ID on both the repeater node (252) and the sensor node (21, the ID it gets from the gw when booted with auto id mode), and I still cannot get the sensor data.

Any idea?

Thanks!

** EDIT ** I tried forcing the parent ID and literally put the two boxes on top of each other and no luck, seems like the repeater is not doing anything but presenting itself...

Also, using MS1.5

Sorry, I was away from the computer for a little while.
I did reuse an old node id, that could have been the problem.
Assigned a new node ID and this is where I stand now:

Firts up: the node sketch:

I don't get errors anymore, but nothing shows up in the web interface.
I think the messages aren't being interpreted?

You have to reboot your individual sensors so HA can see their Presentation message. Your output seems to be good for the gateway itself, but the gateway is not an actual "item" in HA, when it detects the sensors though, you should see their status.

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 have been getting the same thing... it worked on one occasion where it was able to load, but I didnt know the sensors had to "present" themselves at that time... so I made some research, restarted HA, rebooted the pi, disconnected the serial gw... I have been trying at least 25 times since and now I am always getting this:

Well... I feel stupid. I had completely forgotten that I had a Domoticz installed back a few weeks back when I first started searching for the right controller and it restarted when I rebooted the server... when I saw it was loaded, I shut it down and disabled it... then restarted home-assistant, which loaded mysensors perfectly and discovered the PIR sensor as soon as I reconnected it (after the mysensors component was loaded in HA). My guess is it loaded before HA and had dibs on the serial port or something...

I hope it helps someone else!
