I am new to the whole ESP-verse, so I am looking for a bit of guidance.

I am a welder in a fairly hot & humid climate. I have 2x fans setup with Sonoffs which I control with an android app. This works ok but it's a pain having to interact with a smartphone every time I stop/start welding.

Ideally I would like an ESP8266 (or ESP32) in a box with a battery and a switch to control the Sonoffs reprogrammed with Tasmota (or something else?)

Any suggestions and/or guidance would be fantastic, thanks.
