FP300 Zigbee firmware sends duplicate temperature/humidity reports

FP300 Zigbee firmware sends duplicate temperature/humidity reports

Firmware: 0.0.0_5841 (build 20260105)

When reporting temperature, the FP300 sends the msTemperatureMeasurement cluster value 2-3 times in rapid succession. The first values are correct (e.g. 2479 = 24.79°C), but the final value is rounded to whole degrees (e.g. 2400 = 24.00°C). Same issue with humidity.

This causes graphs to show a “comb” pattern as values flip between correct decimals and rounded integers.

Evidence from Zigbee2MQTT debug logs showing raw cluster values attached.

FP300 Temperature/Humidity Flip-Flop Issue - Root Cause Found

TL;DR: The FP300 firmware sends two ZCL reports per sample cycle - a rounded placeholder value followed by the real measured value ~60-80 seconds later. This is proven at the raw radio frame level. it may send more then one duplicate at higher frequency depending on your configured device settings.

Evidence

Raw Ember/EZSP messageContents showing bytes directly from the radio:

19:24:11 messageContents=18290a000029f00a  → 0x0AF0 = 2800 (rounded)
19:25:57 messageContents=182b0a000029200b  → 0x0B20 = 2848 (real)

Full debug log showing the pattern over multiple 5-minute sample cycles:

08:34:21 - temperature raw: 2800 (28.00°C) ← rounded
08:35:42 - temperature raw: 2881 (28.81°C) ← real (+81s)

08:39:26 - temperature raw: 2800 (28.00°C) ← rounded (+224s)
08:40:35 - temperature raw: 2869 (28.69°C) ← real (+69s)

08:44:31 - temperature raw: 2800 (28.00°C) ← rounded (+236s)
08:45:28 - temperature raw: 2892 (28.92°C) ← real (+57s)

Same pattern for humidity - values ending in 00 are rounded placeholders.

Conclusion

• Sampling interval is working correctly (~300s between real values)
• ZCL reporting configuration has no effect on this behaviour
• The device firmware itself transmits two values per sample cycle
• This is NOT a Z2M or zigbee-herdsman bug - the rounded values are in the raw ZCL frames from the radio

Can you provide a more complete ZIGBEE message log?
I need to know:

1. The full ZIGBEE message to pinpoint the issue.
2. The sensor configuration details to reproduce the problem.

OBSERVED BEHAVIOR:

The FP300 sensor sends both precise and rounded ZCL attribute reports
for temperature and humidity measurements.

Pattern observed with current configuration:

• Precise value reported (e.g., 6719 = 67.19%)
• Rounded value follows ~90-110 seconds later (e.g., 6700 = 67.00%)

The rounded values are truncated to whole degrees/percent (raw values
divisible by 100), causing a “comb pattern” in time-series graphs.

This occurs at the raw Zigbee ZCL level (see messageContents hex),
indicating the issue is in the sensor firmware, not the receiving stack.

CONFIGURATION NOTE:

The frequency and pattern of rounded values may vary depending on
sensor configuration. With different settings, patterns such as
“1 precise, 2 rounded” triplets could occur.

Update: Bug appears to be sampling-interval dependent

Further testing reveals the rounding bug correlates with the sampling interval setting:
┌───────────────────┬───────────────────────────┐
│ Sampling Interval │ Bug Present? │
├───────────────────┼───────────────────────────┤
│ 30s │ No │
├───────────────────┼───────────────────────────┤
│ 120s │ No (may need longer test) │
├───────────────────┼───────────────────────────┤
│ 240s │ Yes │
├───────────────────┼───────────────────────────┤
│ 305s │ Yes │
└───────────────────┴───────────────────────────┘
With 240s sampling, rounded values appear but not at consistent intervals - temperature rounds appears consistently - every 1 hour, humidity rounds appear ~20 minutes later, but timing varies.

This suggests a possible edge case in the firmware when sampling_interval approaches reporting_interval (600s) - perhaps insufficient samples collected before a reporting trigger.

@peterChengg, not sure if you work for Aqara: do you have any further thoughts on this?

[peterChengg]

Using your identical configuration, I captured ZCL messages and found that the FP300 does not perform the division by 100 operation you described.
Could it be that the coordinator is performing a read operation on the sensor or similar?
Below are my ZCL messages, which clearly show no two data points are reported within a single reporting cycle (10 minutes).

Indeed, if such reporting behaviour existed, other FP300 units connected to Aqara would show identical patterns in their logs. To date, we have received no such feedback.

Having the same issue.
Temperature value will be sent twice, one is precise value and one is rounded value.
But this doesn’t happen on humidity.

I’m having the same issue, but only with 3 out of the 4 FP300 I bought. They have all identical settings, but one looks like this:

while the others show the comb-pattern:
