Template

{"NAME":"ESP01v4","GPIO":[29,52,0,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":18}

This works without hardware modification on the v4.0 module

Program your 8 pin ESP-01 module with Tasmota and add the template above to open and close it. The relay module will have a blue light when it is open.

There is no add in for the button on the module as it serves as a reset, rather than an on/off switch.

To make this work with v1.0 of the ESP-01 Relay, you must remove R2 (desolder it or just break it off with a screwdriver) and pull CH_PD high (this is easiest to do with a 10k resistor): https://i.imgur.com/79ySGMt.jpg
