I was wondering if anyone has real life experience, was surprised to see this morning I am down to 10% after only a few weeks.

I have had 2 of them since around Nov 15th and both are still at 100%. One is in a place that does not get much traffic but the other is in my kitchen where there is quite a bit of traffic. I am using Home Assistant and the connection is Zigbee.

It’s good!

I seem to have “massive” battery drain on my FP300… installed mine on 30th December (100% battery), and it is already on 32% … and also, not sure why … but my battery seems to show up and down (from Home Assistant reports)

Where are you pulling this data from?

29

This is from within Home Assistant

Based on that abrupt fall, my guess is one of the batteries it came with has an issue. Does the graph still show a consistent level at 32%? Also, those jitters are pretty common based on posts I’ve seen.

Would be happy with a minimum of 1 year

32

1 or 2 years would be great and well worth not having a cord and being able to put these anywhere. Wish I would have bought more when they were in stock

33

One year would be absolute minimum. Three would be great but I am sure that would be in perfect conditions.

34

It seems to have stabilised … but interesting that it is now showing as 41% battery … and definitely still the ups and down

I’ve had TERRIBLE battery life from my FP300. The batteries that came with it lasted about a month, and I’ve replaced them twice. The last one I replaced yesterday and it’s now at 19%, 24 hours later.

Anyone know why? I can’t keep throwing batteries in this thing every week. I am using Energizer batteries that I bought new, so not some cheap unknown brand.

Connected via Zigbee2MQTT into Home Assistant.

How are you integrating your FP300 sensor with Home Assistant?

  1. Zigbee or Matter over Thread?
  2. Paired to an Aqara Hub and then using Matter to bring the sensor into HA?
  3. Using ZHA or Zigbe2MQTT to directly pair to HA via Zigbee?

Without more information, it is hard to know why your battery life is so poor.

Some things to consider, though, for best battery life:

  1. Use the Presence Detection Mode of “BOTH mmWave and PIR”
  2. For Temperature, Humidity, and Illuminance reporting, be sure to either DISABLE or set these to LOW. Excessive reporting of these values will decrease battery life

Have you updated the firmware on your FP300 to the latest version?

EDIT: Just saw you’re using Zigbee2MQTT. What are your settings for this sensor? Remember that if you want to change any setting, be sure to wake up the sensor by pressing the button on it before your make the changes in Zigbe2MQTT.

I’d be happy with a year, however since I’ve had mine I’ve had to take the batteries out and put them back in multiple time after losing connection to the device. Not sure if this is a battery issue, they were only about 3 months old, or if this is a contact issue between the device and the batteries.

Hi, thanks for the response.

The Temp, Humidity and illuminance reporting all on on low, and reporting on threshold and interval.

Have both PIR and mmWave enabled.

I have the latest version of firmware. I was concerned I had some setting messed up so before I swapped the batteries yesterday I factory reset the device, set it back to Thread then back to Zigbee again to make sure the firmware was the latest:
