I am new to openHAB and, as a first small project, trying to control
- eight new Popp Wireless Thermostatic Valve TRV.
For that purpose I have yesterday set up
- a Raspberry Pi 4 with
- a Razberry 2 Z-Wave board
- OpenHAB2 (initially going for the demo config)
Release = Raspbian GNU/Linux 10 (buster)
Kernel = Linux 5.4.51-v7l+
Platform = Raspberry Pi 4 Model B Rev 1.1
Uptime = 0 day(s). 8:10:46
CPU Usage = 1.75% avg over 4 cpu(s) (4 core(s) x 1 socket(s))
CPU Load = 1m: 0.00, 5m: 0.01, 15m: 0.00
Memory = Free: 2.99GB (79%), Used: 0.79GB (21%), Total: 3.78GB
Swap = Free: 2.58GB (100%), Used: 0.00GB (0%), Total: 2.58GB
Root = Free: 8.88GB (64%), Used: 4.83GB (36%), Total: 14.32GB
Updates = 0 apt updates available.
Sessions = 0 session(s)
Processes = 118 running processes of 32768 maximum processes
openHAB 2.5.8-1 (Release Build)
After configuring the Razberry 2 with the native zwave binding, I was able to add the Popp Thermostatic Valves as Things.
So far so good, here comes what I find odd:
- In the PaperUI control section, I can see information for the Thermostatic Valves, but only very rarely/exceptionally the real values (temperature etc.) are shown - usually for all values, -NaN is shown:
- When I edit the configuration of the Thermostatic Valves in PaperUI things (e.g. the name, location etc.) those changes seem to be initially accepted / taken over, but when coming back a couple of minutes later, the values might have been reset to the previous values.
I cannot imagine that this is normal - does anybody have an idea why it happens?
From my layman’s view I find it strange that in the thing properties I can read that
although now it’s 2020-08-27T07:41 and I have tried to set the wakeup interval to 900 sec for all Thermostats…
So far, I have not set up any items, sitemaps etc. as I want to clarify the issues described above first.
Have a great day everyone!
