Heiman HS2WD-E siren turn_on and turn_off stopped working

[sesardelaisla (Sésar de la Isla)]

Hello,

I have two Heiman HS2WD-E sirens integrated into HA from more than a year and they worked fine since I installed them until now.

I have a Conbee II stick with latest firmware installed and I am using ZHA (I don’t have zigbee2mqtt). Regarding HA, this is my setup:

Home Assistant 2023.7.1
Supervisor 2023.07.1
Operating System 10.3

The truth is that I am not sure when they stopped working. I noticed a couple of days ago when I decided to test them after some time, and both sirens entity switches issue an error when try to enable them manually by sliding the associated switch:

Failed to call service siren.turn_on. Unknown error

The entity is displayed fine and switch is able to be slided to either on or off position. However, such error is always issued. I have tried to reconfigure the the device with no success. I also tried to remove the devices and re-add them, but no luck.

RSSI level is being updated with no issues and pressing the identify button works (siren flashes the internal LED).

For whatever reason, triggering the siren no longer works. I always read the breaking changes every time I update the system, and I don’t remember to see any related topic, although I am not 100% sure. I have also tried to search in the forum but I find old information or zigbee2mqtt topics.

Is anybody experiencing the same issue? Any help, please?

After investigating this further, I see the following error in the logs upon trying to manually trigger the siren using the entity switch:

I just created an issue here, but it would be great if anyone else gives further feedback or supports the Github issue if having the same problem.

Yup… My siren stopped working a few weeks ago:

The automation “Front Door Open Sound” (automation.front_door_open_sound) has an action that calls an unknown service: siren.turn_on.

Haven’t had a chance to look into this yet except to see that no siren services are available anymore.

Hi @sesardelaisla,

Since the issue is solved, is this working again for you?

It still does not work for me. It tells me that my device does not respond (and no error in logs)

[sesardelaisla (Sésar de la Isla)]

I switched from ZHA to zigbee2mqtt. No issues since then.
