Really strange, there isn’t any magic to send on/off brightness commands as it’s generic.
Perhaps the problem is something we’re not looking in yet like interference.
A few questions to get a more detailed picture:
Do you use an USB extension cable?
Do other devices in the network accept commands?
What is the ConBee II firmware version? (shown in Phoscon App > Menu > Gateway) The latest recommended version is 0x26720700.
In deCONZ > Help > Debug view
Enable logging for INFO and APS, and try to exec on/off commands, this should show errors status codes.
To answer your question 2: I just added a regular Tuya switch _TZ3000_npzfdcof TS0001 with ZHA (i.e. no deconz) via ConBee2 and the exec commands from the HA UI are working just fine.
I also paired it with deconz (ZHA desactivated) and excec commands from the HA UI work fine.
Debug info when I’m trying to turn on _TZE200_la2c2uo9 from the UI (paired with deconz)
Copy/Paste not working, here’s a screenshot, command executed at 14:53
It’s a tuya device (Smart plug type like all tuya), with no Level Control Cluster, it use the tuya one. The inclusion is event based (need to know the product name during the announce), so it don’t work in 100% of tries. It generaly work with making 2 successives inclusions.
It work at first try using DDF (I have this device too, was my first tuya one)
Interesting, that’s a new error never seen this one before. The 0xAE status in the logs means “APS Table full” I think the outgoing request queue is meant.
A few things:
It’s highly recommend to use an USB extension cable, since without it poor signal is very common and causes all sorts of problems.
Well, I’m trying to pair another TS0601__TZE200_la2c2uo9 device, double inclusion, and still isn’t showing as a dimmable light… It will take me days to pair correctly my 50 devices… I think it’s instable and probably will have to wait for your next release, due in a week or so?
