The problem with Xiaomi is they're just so good, and so inexpensive, and so small, and such nice industrial design.
I'm hooked on these little guys. And now I know that Trådfri outlets, which are also very inexpensive, work to repeat them and all my devices have been very solid since installing them. I've got a real problem now. I'm not going to have an excuse to stop buying these Xiaomi devices!
Every time I have a picture in my mind of what size one of their devices will be, it arrives and I'm shocked by how much smaller it is than I imagined. Every single time! Here's an Ecobee remote sensor that runs on a 2032 cell and reports temperature and humidity every 30 minutes. Compared with the Xiaomi sensor that uses the same 2032 cell and reports temperature, humidity and barometric pressure every 7 minutes.
The only downside I've found with these devices is battery reporting is not very accurate. I've tried playing in the driver settings and I am getting closer but still not quite got it yet.
What I have found out is if they start to continually drop off, then just replace the battery and everything is good again.
I'm using 3.
One on my curtains (yes they are that small you cannot see it) and on 2 external doors.
never had any issues with them.
EDIT: I'm not using any repeaters. Its a 4 bed house but i have got my hub quite central.
It works. These two sensors "Upstairs" and "Bedroom" are both Ecobee remote sensors. But 30 min (which is native to the sensor to preserve battery life) is far too long to make them useful for that. Xiaomi are so inexpensive. I will use those from now on when I need more motion sensors.
@SmartHomePrimer Sorry to piggyback on your thread, but I felt this was an appropriate place to relate an experience I had with the Aqara Temp/Humidity sensors.
Yesterday, glancing at my logs, I noticed the two sensors I use in my showers reporting every 30-45 secs., which is pretty unusual. Digging deeper, I found that the regular 50 minute check-in had become erratic (45 -70 mins). I went ahead and changed the batteries and once the temps stabilized everything went back to normal.
The surprising part, and another reason to love these things, is that they picked right back up where they left off. No re-pairing. No quick press of the button. They just worked!
FYI: Batteries were reporting 2.75 volts before the swap. ~ 9 months on the factory batteries.
Thanks. Wonder if mine will get the same. Just added a temp/humidity about a month ago. Mine has a router right next to it. Might make a difference? At least the batteries are inexpensive, but I hope they last longer than that on average so I don’t have to generate the battery waste so quickly.
