Welcome to a new InTheMail, the most popular segment hosted here on the channel and for today I have lots of really cool gadgets to show so stick around for that.
I’m gonna start the video with this Xiaomi / Honeywell Smoke fire alarm sensor. Obviously Honeywell is a very well established brand when it comes to sensors so Xiaomi partnering with them totally makes sense. There are a bunch of different variants for this sensor available on the market. This one in particular is model number GD-03MI/BB and this is a bluetooth sensor. I wanted a zigbee sensor but I couldn’t find it in stock with Banggood so I had to go for this bluetooth one, it shouldn’t be a major issue as I have bluetooth connection on my homeassistant server as well. That’s the plan to connect this via Bluetooth to homeassistant so that I get smoke alarm capability via HomeAssistant.
You could also use this with a Xiaomi gateway and get the notifications in the Xiaomi app but I prefer to use HomeAssistant and this device seems to be supported by the Passive BLE integration which should automatically discover it. This sensor uses a CR17450 lithium battery which is not that common and they tend to be more expensive because of that, luckily it does come with an included battery which should last up to 5 years according to the datasheet. I would be happy even if it lasted just 2 years and would consider anything above a bonus.
I have yet to test this, I will be running some tests after installing it but I can tell you that it also provides local light and sound alarm so you don’t need to rely on having it connected, it will sound it’s 80dB buzzer when smoke is detected and just considering that it uses Honeywell sensing technology with the higher quality of Xiaomi products, this has to be more reliable than the no name brands that you can find online so if you are interested in getting one, there will be a link provided in the description below.
