Re: Hardware Support Request

The HC-SR501 PIR motion sensor is already supported because it actually works like a switch.

The I2C INA219 board would be usefull to measure DC-currents. I support the request.

I have several different USB serial interfaces they all work the same. CrossConnect RX and TX. Connect ground and 3.3V.
How to flash, connect may be different for the different versions of ESP boards.

Did you connect the CH_PD also called Chip_Enable to Vcc ?

You best look into the monitor screen to see what errormessages you get.
