why you didnt define an uar.write sensorStart? could you post your yaml platform template configuration? i am getting errors with mine.
Edit:
so this si how it should be coded? it doesnt seem to work.

- platform: template
name: "turn off mmwave led"
id: "turn_off_led"
on_press:
- uart.write: "sensorStop"
- delay: 1s
- uart.write: "setLedMode 1 1"
- delay: 1s
- uart.write: "setUartOutput 1 0"
- delay: 1s
- uart.write: "setUartOutput 2 1 1 2"
- delay: 1s
- uart.write: "saveConfig"
- delay: 3s
- uart.write: "sensorStart"
- delay: 6s # the sum of mmwave_sensor delays

Great work! Will you publish the V2, @EverythingSmartHome ?

Just came here searching and asking for this.
Will you publish the code for this V2?

Since I have the stuff home, I'll build one, if it works nicely you can expect a new client for a maybe 4 units.
