Additional information

Phoscon shows it currently as two On/Off lights. I have installed the T2 behind my existing roller shader switch to make it smart. While moving the shader up by activating the corresponding "light" worked, the other "light" for the down movement didn't do anything. I'm running the docker image deconzcommunity/deconz:2.26.3 on an Intel NUC with Conbee II.

FWIW, I'm using 2.25 (via the community HA addon) and controlling a garage door using the T2 in a similar way (toggle each light on/off for a second to start the door moving either up or down depending on which light is chosen). Maybe I will hold off moving to 2.26!

Also, I have another T2 module to control a bathroom light and extractor fan and I am experiencing problems with the second relay output reporting that it is off when it is actually still on (the second relay is running the extractor fan). It correctly reports being on for an hour but then gets in a repeated pattern of reporting turning on / off every 5-15 minutes (but it is definitely still on).

Hoping that officially supporting this module might fix this?

Hi there.

Unfortunately, the screenshots indicate that the clusters have not been read properly. This page explains how to read clusters. Please take new ones and update the issue accordingly. Thanks a lot!

Hi @SwoopX, thank you for the advice. I will prepare new screenshots based on the explanation page but it will take me some time to do so. I will update you when done. Maybe @gee-jay-bee can (optionally) help out to speed up the process ;).

@SwoopX sorry for the delay, here are the new screenshots:

This time both up and down movement worked just fine, I'm not sure why it didn't work the last time.

Anything we can do here? For me right now two options are missing: Measuring the power consumption (like the Aqara smart plug SP-EUC01 - lumi.plug.maeu01) and the child lock (like the Aqara Thermostat E1 - lumi.airrtc.agl001).

Fwiw, I was experiencing some challenges with Deconz + Conbee II and finally took a chance on Zigbee2mqtt with a newer USB coordinator. This T2 is natively supported there and good news is the drop-out issue I was seeing isn't happening. There is power reporting (though it seems to be the combined power of both relays) but I don't see child lock. You can disconnect the relays from the inputs.

Deconz served me well for many years and I hope the new DDF strategy can accelerate device on-boarding. Good luck!

[moddavid]

I would rather don't stale this ticket for now. Maybe I find some time to compare the DDF files from the mentioned other devices to see if I get it somehow to work as intended.
