For more accurate energy consumption measurements this device requires power monitoring calibration.

Flashing

Flash using Tasmota Web Installer and select tasmota32-lvgl option.
For esptool.py download f.e. tasmota32-lvgl.factory.bin and run esptool.py write_flash 0x0 tasmota32-lvgl.factory.bin.

• Relays
• Status LEDs
• Screen
• Touch
• Power metering based on pulse counter (needs power calibration)

Not working:

• Voltage and Current metering due to the HLW8012 CF1 & SEL not connected on mains pcb
• Temperature measurement incorrect or not available on later pcb versions

Use this basic script to create touch buttons

>B
dt [B1x50y10f2]Lanbon L8
dt [b0:20:60:200:60:10:16:1:3:Relay 1:]
dt [b1:20:140:200:60:10:16:1:3:Relay 2:]
dt [b2:20:220:200:60:10:16:1:3:Relay 3:]

Buttons are automatically assigned to relays.

You have to do further scripting to set behaviour of status LEDs, turn the screen off after a timeout and display more on the screen.
