[SOLVED] Girier JR-ZDS01 (TS0001 _TZ3000_zw7yf6yk) is giving out "Failed to deliver message"

So, the device physically works, whenever I press on it, or on the light switches, the light turns on.

The pairing initially was succesful (I tested first by only inserting power cables), and when I finally connected everything together, I realised that it shows me all these configurations and sensors, but I can not act upon them, constantly getting this message:

Failed to send request: Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>

I am very much new to this whole thing, all I can say is that I bought the product due to it existing in the compatibility list. It seems like the same exact product, only that the Zigbee ID is different (_TZ3000_zw7yf6yk).

I tried deleting device from ZHA, powering off the house and back on, re-pairing a million times… and, BTW, I could not re-pair again one single time; ZHA is actually the one who automatically makes it appear again on the list, even after me deleting it and a HAOS reboot.

How could I start debugging this? Is there any chance of it working?


UPDATE

Came back home and suddenly I could turn it on, but turning it off failed… somehow in the following minutes this improved to a 60 to 70 % success rate… and finally, I moved my coordinator a bit closer to the area, and… yep… it might have been an issue with signal strength, because now it always works.

Anyway, I bought some Sonoff ZBMINIs that will serve me well (and actually cheaper when bought in bulk!).
