Looking for a reliable smoke detector

[dannybloe]

Howdee folks,

Currently I have 4 Fibaro smoke detectors in da house but I'm not happy with them as they keep generating false alarms. So I am looking for an alternative (zwave). So, I am particularly interested in how reliable they are. No false alarms, no lost connection with the zwave network etc.

Any tips?

I have one of these which I am happy with, it's Zigbee, I use a CC2531 with Zigbee2MQTT to communicate with it.

I'm also getting Battery level and Signal info into Domoticz.

I've not had any false alarms so far and I've tested that it works by smoking a cigaret.

But it has to be zwave.

Your going to get a Zigbee interface at some point, it may as well be now... (just saying).

I've got Z-Wave, RFXCOM, Zigbee etc... I like flexibility to buy devices I want.

I have 6 Fibaro 's and am very happy with them. You just need to use rechargeable batteries and replace them regularly.

I'm using KD101, works like a charm. Also it is good to replace batteries once a year (just put it in your calendar)

I'm using 6 Fibaro's without any problem. After channing the battery (every year) once in a while I have to do a manual wake-uo by pushing the B button.

Funny, when i look for those on Google, I get all kinds of links back to Domoticz, but not to the smoke-detectors them self.

It was never an issue of batteries. Out of the blue they went off without any obvious reason. Once a year wouldn't be a problem but twice in 2 months is not ok.

One or all of them?
Any chance there's dust in them?

Maybe it is better mentioned in the RFXCom manual

I think you can't order the KD101 anymore, I have Alecto SA30's (external/internally the same as KD101) and those are supported by RFXcom also.

I have two that also works correctly. But I also noticed they send an alarm-off every times Domoticz restart (after a raspbian update needing a raspberry restart for instance, or Domoticz hangs & restart), usually after a few hours (probably at the time they first wake-up to get possible configuration updates after Domoticz restart).

But i never got a single false ON alarm in almost 2 years.

If this occurs out of any Domoticz restart, I think if your z-wave interface is soft-reset sometimes (OZW seems to do this as a defensee if z-wave network becomes silent for a Domoticz-side configurable time-out), I think you may also get some spurious off. This may just be an hint to debug something wrong with your z-wave network?

IMO, having false-on would be a problem... But off, not really.

Mnah.. there was no restart during these false alarms. Never see that happening though.

Take a look at the smoke sensors from POPP.
They use a good brand for the smoke sensor (Ei Products) and they installed a Z-Wave module inside the sensor.
The smoke sensor has a build in battery and the Z-Wave module uses it own battery.
