I know I can do it with ZWave-JS-UI. I’m not currently in the mood to start the transition process for this little thing.
I’m assuming that the wake up interval anyway is going to be sent to the multisensor via a standard Z-Wave call, hence thinking it should be possible to do it not using the GUI, but just performing an action call.
It is a long time since I gave up setting parameters on a FGMS-001 with openHAB as they didn’t reliably change behaviour regardless of what the Fibaro docs said.
This suggests HC2 has Z-Wave binding has a different definition from HA & openHAB (although the latter now uses ZHA apparently - it didn’t back then).
I can say battery life on FGMS-001 increased a lot moving from old openHAB to HA which might fit with less time awake.
Before a quick check, I was going to say mine only update every 4h-ish, but the Temperature Report Interval parameter seems to be working somewhat here:
The same sensor was working fine on my previous Z-Stick. Unfortunately, this died and I moved over to Z-Stick 10. Have not been able to get the sensor to work properly after the move.
I have two sensors on firmware 2.8 which are not working properly. The one on FW 3.4 works fine. And 2.8 is the latest available for those two.
