Hacks for this device family
From the Sonoff relays and switches fiche: what owners already do with devices like this.
Easy~15 minNo risk
Switch it with no cloud, no firmware change
Use the documented DIY HTTP route for BASICR3 and MINIR2 with firmware 3.5.0, after checking the model and saving settings you will need to recreate.
An evening~30 minNo risk
Keep the rest of the fleet working without eWeLink
Log in once to fetch each device's encryption key, then Home Assistant talks to it over your network from then on, no DIY Mode needed.
Hands-on~1.5 hCan brick it
Replace the firmware with Tasmota
Opening the case to reach a serial header, and sometimes soldering, gets you local MQTT and HTTP control with eWeLink dropped entirely.
