Nodon SIN-4-RS-20 roller shutter module not working

Configuration Zigbee

Hello,

I am trying to use a NODON SIN-4-RS-20 Zigbee roller shutter micro module that I have recently installed as a test on one of my wired roller shutters.

The module is detected successfuly by the Zigbee coordinator (SkyConnect USB key) and I can see the device in the network map:

It is also present in the Zigbee devices list:

However when I pres the up or down arrows to open or close the shutter nothing happens.

I’ve double (tripled) checked my wiring and compared it to the installation diagram and everything seems ok:

It’s also worth noting that nothing happens when I press the buttons of the physical switch but this time I can hear the relay clicking.

I have searched the logs and can see the following exception each time I press the up/down buttons on the cover card:

I don’t know where to look or how I can investigate this further… any help would be greatly appreciated :grinning:

In the evening I tried another module from a differnt company which also uses Zigbee protocol (MOES Smart Curtain Switch) and the result is the same: I can hear the relay click when I press the physical switch buttons or HA virtual buttons but nothing happens.

However there was no exception message in the logs except for the following error:

[546881926720] Error handling message: Unknown error (unknown_error) Julien from 80.9.238.186 (Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36)

I tried to connect the Nodon module once more and this time the behaviour was identical to the one with the MOES module: relay clicks when I press physical switch buttons or HA virtual buttons but no effect on the shutter.

And only the Gecko unknown error in the logs.

If I remove the module and connect the physical switch directly to the shutter again, it works :thinking:

Found it: it was related to the fact that my shutter motors need to be connected to the live of the physical switch.

Now it works, the shutter goes up or down if I press the up or down physical/virtual buttons.

However it seems that there are compatibility issues with Bubendorff motors, but that’s another story.

I am just now testing this relay with a German motor from Selve. It seems to me that it worked from the first. I still have to put the tube and the canvas, but so far it’s OK.

I bought the relay at your suggestion. :slight_smile: It’s OK with ZHA.
