Just added two Heiman smoke detectors. I tested one with real smoke, which worked fine. But now the alarm mode remains on. (exclamation mark in homey dashboard). Is there a way to reset the alarm? Thanks, Rolf ---

I don’t know these smoke detectors but for KAKU door open/close sensors there is an advanced device setting where you can set the time that the alarm should stay on. ---

The only advanced options are: group 1 group 2 wake interval enabled Interval 86400 seconds secure battery device ID 22 manufacturer 608 Product type ID 32770 Product ID 4096 Firmware version device class (basic) device class (generic) device class (specific) I don’t see where to set the time?

Hmm ok. That wake interval looks like it is not working correctly, or we misunderstand its purpose. I think you should contact the developer of the Heiman smoke detector app. He/she may add the extra functionality to it. ---

I added the device as a general Z-Wave device, while the Heiman app was installed. Not the detectors work as should, alarms disappear after a few seconds. Son’t know if this has really helped, or if I was lucky, but still; is seems solved for me… ---

Hi Gents I’m very sorry for my absence in this thread. The last few months has been a bit crazy and the whole corona situation not exactly helping… 😅 So I cannot promise an imminent fix, but I will address it as soon as possible! 🙂 ---

Hier hetzelfde probleem.Set van 4 gekocht, 3 zijn ok, 1 blijft in de alarmmodus en piept om de 10 minuten. In Homey staat een uitroepteken op de tegel. Heeft iemand inmiddels een oplossing gevonden? ---

I arrived on this Thread while looking also for a solution with my Heiman smoke detectors (v2) remaining in alarm mode (after a tests)… As far as I am concerned, only 2 out of 3 detectors are remaining in that alarm mode ?! First detector ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/4/a4c7d71dc09e330a25f2f737c8e071e047ac9580.png) Second detector ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/0/2097637cc13b575723224779d65328695db70aae.png) Third detector ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/4/84c56c34cb7cef369adea20ccc74a450a721b73a.png) No idea why/how the third one went out of the alarm mode… Actually, one can see that the first one went “off” two times before being stuck “on”… I did wait a bit (2 days) before considering that the 2 first detectors were “stuck” (as the wake-up interval of these Z-Wave devices is 24 hours). But nothing changed… I also tried to remove temporarily the battery, but it didn’t help. Now, if I do a new test with one of the detectors being stuck, I don’t even get an event anymore… I finally did reset one of the two detectors being stuck, and after pairing again with Homey, alarm is going off immediately at the end of each test… ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/9/c974c308620fcd8d7929ac44bd1014d2d2f2f244.jpeg) When I used OpenHab, there was a feature to “health” the connexion/state of the Z-Wave devices… Is there anything similar with Homey ? Or resetting the device is the only option ? ---

There’s some Z-Wave tools in here [https://tools.developer.homey.app/tools/zwave](https://tools.developer.homey.app/tools/zwave) Also make sure you limit update interval times from ‘chatty’ devices, like certain Aeotec sensors are/were. They can disrupt a good functioning mesh network. ---

Great, Many thx Peter, Very interesting ! Looking in that tool; I see that all the Heiman smoke detectors are “unreachable”. One, named “Smoke Sensor Office”, is even “offline”. I don’t get that, as this one is really close to my Homey Pro (same room) I did press its test button… and immediately, in Homey, its alarm turned on. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/4/7447dc022cedc685788c60555784f9bd22ccb3b4.png) But really weird: it still appears to be “offline” and “unreachable”. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/e/ced43a9d4ec51113e130f57d67a286409199fb33.png) And if I try to “Heal” my Smoke Sensors, I get an error “request\_timeout” (And it does not help with sensors stuck with alarm turned on) Anyone else with Heiman Smoke Detectors (in alarm or not), being reported as “offline” and/or unreachable (but still reacting on a test) ? ---

Hi Valéry, YW! I’ve very limited Z-Wave knowledge, but I do know, for battery powered Z-Wave devices the “unreachable” status is perfectly normal. This is because those devices are in sleep mode when inactive. (Same goes for Zigbee battery powered devices). So, when the the smoke sensor sends a signal to Homey, when its test button is pressed → all’s fine.
