As I mentioned in my post from November '18, the “broken save” issue in PaperUI was fixed and I was able to switch the siren on and off via its “switch_binary” channel.
Update: Last weekend, I finally tested changing sound and volume via PaperUI. However, I could not use the two separate settings “37: Siren Sound” + “37: Siren Volume”, but had to use the combined “37: Sirensound and Volume” field. (see red vs. green circles in attached figure).
I’ll test it again with Habmin tomorrow.
What I noticed, though, is that whenever I update this device configuration parameter (sound/volume) and press the apply button, the siren starts to howl and I have to push the switch button to off.
Also, the item provides a channel “config_decimal_param37”, but this channel cannot be queried nor set…
EDIT: Sorry, the last statement was incorrect. I’ve used a wrong format in my items definition.
The named channel could be queried.
