![[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)](https://obrazki.elektroda.pl/1000454900_1749493372_thumb.jpg)
I got this sensor from Aliexpress and installed openbeken on it using some soldering via serial.

After playing a little bit i come up with this config:
Calibrations:
Battery, as per BK7231 flasher text extracted from tuya
Temperature
Comparing with a bunch of other chinese sensors and calculating the average
Im posting this to have it for future reference and to update later with changes.
EDIT 2025-02-07: Autoexec script
Operation modes:
Loop mode: The device will turn on with the wifi led also on, publish mqtt, go to sleepp 600seg and start again.
Maintenance mode: The device will stay on for 600s with the led blinking, then reboot to normal mode. This 600s must be enough to do any required change in the configuration while avoiding keep the device powered on too much to kill the batteries.
To enter maintenance mode, you press the internal button while the led is on. If the device is sleeping, when you press the internal button it will turn on, an then, while led is on you can enter maintenance mode.
To exit maintenance mode, just wait 600s or press the internal button while led is blinking.

Device configuration, as extracted from Tuya:
- ALT pin on P16
- Battery Relay on P17
- Battery Max Voltage: 3000
- Battery Min Voltage: 2350
- I2C SDA on P9
- Button (channel 0) on P20
- I2C SCL on P6
- Battery ADC on P23
Device seems to use Battery Driver. See more details here: https://www.elektroda.com/rtvforum/topic3959103.html
Device seems to be using CBU module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424
