Had a coupple of hours to kill today. So I sat down and upgraded my openhab “test” setup from 2.5.3 to 2.5.4.
This setup is very simple. Its a Odroid C2 running Ubuntu and openhab, with Zigbee and Velbus bindings activated. Thats it.
Zigbee devices are:
Philips Hue motion sensor
Philips Hue Switch
Xiaomi Mija Motion sensor
Trust Motion sensor.
Osram plug outlet.
Traadfri motion sensor (not running as it has been confirmed it doest work with the binding).
I previously gave up on Zigbee a few times. But I decided to test Zigbee binding each time I have upgraded this openhab system. Just to see if there will be any differences.
Previous symptoms has been:
Most devices stopped working after a few hours or within a coupple of days all by themselves. Those devices who may still be running maybe for a few days, the first restart of openhab will kill them for sure. Thats the most typical scenarie.
Notice - I do NOT do any changes to this system. When all things/devices are up running, I just leave it running by itself.
Today I wanted to try something new. After successfull upgrade of openhab and system files to openhab 2.5.4 I started to clean up the system.
First I deleted all Zigbee devices, and reset them as well (all except the Hue motion sensor were offline anyway).
Then I edited the setup of my EMBER coordinator to use channel 15 - Thats the new part.
Then I started adding the Zigbee devices one by one again, except the Osram Plug. Reason is, this Osram plug had previously been the first device to stop responding most of the time. This time I wanted to see what happened, if I dont add it.
After adding all the devices successfully, they all seemed to work and responded fine. Thats not abnormal.
After quite a few minutes where I made sure all devices were running and responding, it was time to do the fatal “restart openhab test”.
Status result after restart:
Philips Hue motion sensor:
It came online fine, but does not respond at all. After ½ hour beeing online, it changed to offline
Philips Hue Switch:
It came online, respond fine
Xiaomi Mija motion sensor:
It came online, respond fine
Trust motion sensor:
It finally came online after quite a few minutes. At first it didnt respond, but after a few more minutes it started responding. At the time writing, it´s still responding.
Its a surprise to see the Philips Hue motion sensor failed. Normally this device is the only one which continues to work when the others fails/have turned offline…
Lets see how long it last for the other devices this time. I do not hold my breath to be honest! What I see this time I have seen many times before (except for the Hue motion sensor failing). My bet is they will all stop working within the next 1-2 days. If not, I´ll redo the fatal “restart openhab test” to see who will survive. Stay tuned!
