Can you send me the update file ?
Thanks a lot for your work !
As suggested, please send v2.2 OTA file. Thank you!
Hi @leoXie, I'd be interested in the OTA file too !
Hi @Milo73, I bought 5 units last week and as the author seems busy, can you share me the update file he sent to you ? I want to test the update before take the decision of return them for the PLUS model in the last few days.
Thanks !

As requested by many others, I too have 4x the old version and would love to try the FW update. Please send v2.2 (or latest) OTA file. Thank you!

@leoXie Hi, I just bought a HS1SA-E: [2026-06-07 10:21:21] zhc:tz: Read result of 'genBasic': {"appVersion":19,"dateCode":"20241221","manufacturerName":"HEIMAN","modelId":"SmokeSensor-EF-3.0"}

Hello @leoXie , could you send me the OTA file?
I would like to update my HS1SA-E´s (manufactured in 2025)
Can i also get the latest firmware version for my 3x

does this also work for an older model CO sensor? the HS1CA-E? Or do you have a newer firmware version as this device goes unavailable at least once a day everyday for about 1 min. And i have a lot of zigbee devices not seeing this issue with other devices in the same room.

I would like to share my experience and thank you again for your work.
I updated my 6 units (it take some time) and they seems to work like a charm with z2m. I can now use them as sirens with alarmo.

Hi Orange,
regarding the CO sensor, how far is it from nearest zigbee router device? did you use it with ZHA?
Hi LeoXie,
My CO sensor is about 2 meter away from the first HUE lightbulb (router device) and within 3 meter there are 3 more lightbulbs.
No, I'm using Z2M latest version.
Hi Orange,
could you move the co alarm to another router? power it down and then power it back up?
Are there many battery-powered Zigbee devices as well?
Hi @leoXie, could you send me the new firmware file ?

Blockquote I updated my 6 units (it take some time) and they seems to work like a charm with z2m.
Could you describe how you updated? I'm using the OTA update button on the device page, but it won't work for me. This is what I get in the logs of zigbee2mqtt (version 2.12)
z2m: OTA updating 'Sensor_Smoke_Kitchen' to latest firmware
z2m: OTA update of 'Sensor_Smoke_Kitchen' failed (Device didn't respond to OTA request)
Hi @leoXie,
could you send me the OTA file?. ZHA: SmokeSensor-EF-3.0 by HEIMAN Firmware: 0x00000014, ZMQTT "device": {"applicationVersion": 20, "dateCode": "20251023", Thanks in advance!
