I can not pair the sirene to zigbee2mqtt. I can reset the sirene, i can see that LEDs show “ready to pair” but i do not see a single char in the logs of zigbee2mqtt or a reaction in the webfront end.
Did someone successfully connect that sirene?
Or can you recomment an other hardware like this one?
I successfully pair the Heiman using the ConBee-II stick and CC2652RB stick.
I do not use the CC2531 stick.
Thanks for your reply. I fear that Heiman and the CC2531 do not like each other…
Maybe you have more devices in your Zigbee network than the CC2531 can handle?
I thought 20 devices was the maximum.
Hmm. did not know that this is a hard limit… could be around 20… have to double check this
17 devices at the moment.
Are you pretty sure about that limit (20)?
“Adapters based on the CC2530 or CC2531 chip are not powerful and not recommended for networks larger than 20 devices.”

I changed two things:
New USB Adpater: CC2652RB
New Siren: Tuya TS0216
This works pretty good.
