Dear All, Hope everyone had a brilliant Christmas! :christmas_tree:, wish you all had a wonderful and relaxing holiday break with your loved ones. I previously shared a proposal for adding new features to our smoke alarms on the Heiman zigbee and matter smoke alarm proposal - Hardware - Home Assis…

@leoXie Hi Leo could you also send me the firmware update file for the HS1SA-E and the procedure to apply it? Bought it yesterday, read about the plus later on. Would love to be able to mute the alarm remotely as we have pets in the house. Thank you, Guy

Hi @zanechua sorry for reply late. The Zigbee version of the HS1SA must use the blue-and-white packaging. All other packaging versions are older versions. [image]

So I’ve tried using the HS1SA-E Plus as a Zigbee siren for home security. There does not appear to be a way to do this cleanly using an automation in ZHA as the only options to turn the siren on via a trigger appear to be via remote test button or warn, both of which give just 3 or 4 siren bleeps. I…

Volume control on the HS1SA-E Plus, via ZHA, would also be useful. If its already there, apologies, but I can’t see it.

Hi @MisterB could you try to give it a duration? this is a workaround for ZHA, it may fixed in the feature. action: siren.turn_on data: duration: "200" target: entity_id: siren.heiman_hs1sa_ef_3_0

Due to the limited resources of the chipset, we are unable to add volume control to the HS1SA-E Plus. However, that is a great suggestion—thank you! We will consider adding this feature to our future models.

Thank you for reply. Couldn’t get duration to work, but I’ve achieved similar effect by having an Action repeat Press Alarm multiple time.

if you would like to solve this issue, you can replace my quirks file, and it will exposes two types of sound in HA. In order to be consistent with HA, so the merged quirk was using standard zigbee siren operation.

Understood. I still think there there may be demand for a battery powered alarm in the same style as HS1SA-E but without the smoke / CO2 detector elements, just a simple siren but super configerable (eg volume, tone type etc). I can see several uses for this besides a security alarm. eg fridge open…

Thanks for sharing the idea. is it common for users? if we add configurable siren to smoke or CO alarm, would it be better?
