for me a remote mute would be awesome. if the impact on battery life is not very major, I am ok. also, a grouping would be nice if for example we have more than one detector, make them all or some sound the alarm if one detects the smoke, i have a detached workshop that is on the same zigbee network but i doubt i would hear a siren from that space in my house.can we test the firmware somehow?
sure, let me DM you and guide you though it.
Hi. I own HS1SA-E. Who can help me with getting firmware for upgrade?
Thanks
Z2M shows:
Zigbee Model: SmokeSensor-EF-3.0
HEIMAN: [HS1SA-E]
Hi. I bought an HS1SA-EF, but there are no updates available and the siren doesnât work. How do I update it using ZHA? Is there a custom file?
I am pretty sure there is a custom FW file. Also awaiting for the reply related to this topic ![]()
Hi Leo,
Yes, this is for the Matter version. This looks exactly like what I would be looking for. Thank you very much. Looking forward to seeing the update released.
Hi Lvdx,
Could you read the datecode of it for me? thanks.
great, we are trying our best to get it merged.
here it is
25.04.2026, 17:52:18] zhc:tz: Read result of âgenBasicâ: {âappVersionâ:19,âdateCodeâ:â20241221â,âmanufacturerNameâ:âHEIMANâ,âmodelIdâ:âSmokeSensor-EF-3.0â}
Thatâs possible, could you PM meďź
The datecode for me, using ZHA is 20251023. I thought this product was plug n play but itâs not
Hi Lvdx,
I am so sorry for that, could you show me the model as well? maybe I can help you update it.
The product is able to buy from here:
I also have an alarm with the date code 20251023 that I would like to get updated firmware for please.
The model is SmokeSensor-EF-3.0
Why did you recommend buying the HS1SA-Z? I thought the HS1SA-EF was the superior model because of its siren control.
it was not updated with english language for FR and DE region, it should be HS1SA-E instead of HS1SA-Z. but the link is correct link.
it may take a while to get updated.
would you like to try it out?
Yes please. I contacted you via email yesterday and I have sent the requested details though. I really appreciate how responsive and supportive you and Heiman have been to the Home Assistant community!
well received.
Iâm not getting a clear picture on the FW upgrades and what it brings.
I have both a SmokeSensor in HS1SA-E-PLUS version as well as EF-3.0 (i.e. not a PLUS).
The PLUS has the ability to use HA for setting off the siren (enabling HA assisted network of smokesensors), remote testing it and remote muting it.
Is it now possible to FW upgrade the EF-3.0 to have (some or all of) these same functionalities as the PLUS has?
If the answer in âNoâ: clear.
If the answer is âYesâ:
- where can I get this FW?
- which of the PLUS functionalities would be available on the EF-3.0 after FW upgrade?
- and I guess, how do I do the FW upgrade?
Does anybody have clear answers to my questions? Much appreciated.
Thanks!!
