Sonoff mini installation

Imagine those those two switches is a single switch. Then the only complication is to find where they actual become one and output power to the light/s. Once you have that, that is what needs to be used on a mini as if it was a single switch.

That is the simplest way I can explain it, and how I did a 2-way switches on a single shelly. Works 100% for me.

Similar to how @Gielie01 explained it to me, the help I need is to identify the different wires, which are live, which are switched, etc, etc. That wiring diagram you posted looks frightening though :ROFL:

It is simpler than that from what I understand, the Mini essentially replaces the one switch in the electrical wiring but is able to take an input from the switch it replaces as an input.

Never mind, in order for the Mini to do the switching and know the status of the light, it replaces both switches and then uses the input from both switches to turn the light/s on or off.

Replaces the switching function of the center switch in that manual three way diagram.
 
So glad my house doesn't have 2-way switches, seem to complicate the Sonoff installation just more than necessary.

I did end up installing another 2 Mini R2's this weekend but with a twist:
- One is connected to a light which currently has a Yeelight running. The Yeelight is nice in that it can change colors and dim down to "moon mode" which is just a barely there, yellow-ish light. Kids enjoy it as a nightlight.
- Other one is connected to a Yeelight as well, in the bathroom, but just a simple white-with-dimming one. But it is also connected to an extractor fan running on a Sonoff Basic.

So the main problem is, I don't actually want the relays to turn off since I control the Yeelights from Home Assistant. But I do want the physical switch to control the lights. And I do want the ability to actually physically turn off the light/on when Home Assistant is down.

So I ended up flashing Tasmota and using the button/switch settings and rules to do the following:
- One click (I use momentary, dimmer push-buttons instead of throw-switches) - sends a MQTT message to Home Assistant, which then toggles the Yeelight.
- Two clicks - sends an MQTT message directly to the Sonoff Basic to turn on/off the extractor fan
- Click and hold for 2 seconds -- toggle the relay locally/directly (no Home Assistant involved).

Works very well. Going to be installing more momentary push-buttons in the future - it is still familiar enough that most people will be able to just "use the light switch", but it gives you much more options since you can use a lot of additional click-types to do more things...
 
The sonoff is not good at 2-way/3-way switches. You can make it work but a shelly is a much better option for these.

Momentary switches work great, ive been using them on sonoff mini's for a while, and help extend the convenience factor while keeping up WAF. 2 of mine are setup to turn on the lights in a room on a single "click" but when they are held down for a second they turn on the lamps in that room, works well.
