Tuya Air Quality Sensor Fake CO2: What It Really Measures
Tuya's TS0601 air quality sensor reports CO2 without a CO2 sensor. What Zigbee2MQTT's docs and user tests show, and what the device is still good for.

A Tuya TS0201 reporting humidity about ten times too low in Zigbee2MQTT has a scale bug, not a calibration problem. Here is what actually helps.

Set up supported Tuya TS0203 variants in Zigbee2MQTT, identify the manufacturer string, check the documented false-contact fix and test battery reports.

Compare Aqara WSDCGQ11LM with the T1 family, including its TH-S02D alias. Check model IDs, readings, OTA support and the separate W100 option.

Pair the SONOFF SNZB-04P with Zigbee2MQTT or ZHA: CR2477 battery, mounting, MQTT states and current tamper support, with practical checks for older setups.

Why Home Assistant's Xiaomi BLE integration still wants your Xiaomi login, what a bindkey is, and when flashing custom firmware removes that step.

Diagnose stuck or implausible Zigbee2MQTT battery values: raw scaling, voltage curves, stale reports and model-specific low flags, with practical checks.

Pair the Tuya TS0202 PIR sensor in Zigbee2MQTT and check your manufacturer code: some variants expose sensitivity and keep-time settings, some don't.

Aqara pairing mode isn't one procedure. Sensor, switch, and H2 Thread-mode gestures for Zigbee2MQTT and ZHA, plus why a device never appears.

Some Zigbee routers can't keep Aqara or Xiaomi sensors connected. Which brands are documented as failing, why it happens, and the fix to try first.
