I have a MOES Tuya lightswitch that is detected as ‘generic device’ in ZHA. Supposedly, it should have backlight, but it seems it can only be enabled trough the app. I can see that ZHA supports other similar devices, so I’m trying to simply find and set the right attribute.
(I’m really new to all HA stuff, maybe 10-15hrs in in total, but not new to programming, tinkering with phone firmwares etc, so I kinda have a vague idea of what I’m doing)
From what I understand this device is not supported in ZHA directly, but as a generic lightswitch it works fine, all buttons trigger both ways (to and from the dashboard) and I was able to do a few automations between a couple of these switches.
To find out what the backlight might be I had a look at ZHA device handles source code and I can see that it’s supposed to be cluster 6 (on_off) attribute 0x8001.
class TuyaZBOnOffAttributeCluster(TuyaEnchantableCluster, OnOff):
"""Tuya Zigbee On Off cluster with extra attributes."""
attributes = OnOff.attributes.copy()
attributes.update({0x8000: ("child_lock", t.Bool)})
attributes.update({0x8001: ("backlight_mode", SwitchBackLight)})
attributes.update({0x8002: ("power_on_state", PowerOnState)})
attributes.update({0x8004: ("switch_mode", SwitchMode)})

I did a scan on the device with the toolkit and I can see the general structure is quite as I’d expect with 0x8001 and 0x8002 attributes where they are supposed to be as far as I understand.
However, when I read 0x8001 attribute it’s already set to 1 (on every button of every switch), which is somewhat suspicious. Also when I write pretty much anything into that attribute nothing happens.
I did confirm with the read that the write was successful, and writing directly into on_off attribute triggered the switch so writing seems to work fine, just the value itself doesn’t seem to trigger anything.
Is there a trick to writing those values, or should I be doing something extra after pushing the value in, idk, some sort of ‘commit’?
