Sonoff mini circuit diagram

You could install a crossover switch the middle one and then use one channel of the pro as one of the end switches. Or you could use two channels of the pro in interlock mode to function as the crossover switch. Replacing the center crossover switch with two channels of the pro would look like this:. If you just want to replace one of the existing switches with the pro then the diagram below applies.

In this case on one channel of the pro the common would be say for the left switch the "hot" wire with the NO and NC connected to the other two wires. Replacing the right switch the common would go to the bulb center pin with the NO and NC connecting to the other two wires.

Not sure what you mean by "on" with a 3 way switch. The common always connects to one contact or the other. In the case of a relay when it isn't energized the NC is connected to the common and when energized the NO is to the common. To replace the left switch with one channel of the pro. The hot wire goes to the common on the relay.

Please help me understand the SONOFF Mini

The top red wire connects to the NC. The bottom black wire goes to the NO. With this connection current flows exactly like the diagram when the right switch common is connected to the top red wire. Energizing the relay OR switching the physical switch will turn off the light. All I can do is provide the diagrams. If you have two existing 3-way switches and wish to keep both of them then use the diagram above to add a 4-way crossover switch between them using two channels of the Sonoff in interlock mode.

It will work if you wire it correctly. Keep in mind that the Sonoff requires an always hot wire and a neutral to power it.

It cannot be powered from either of the two "traveler" wires. One of the two channels used has to be energized at all times. Having both channels d-energized will not work. For example if you use channel 1 and 2 then you only switch on ch 1 or 2 in the app with ch 3 and 4 never turned on.

I was thinking of connecting one of these physical switches to sonoff so that I can control the light using the physical switches and eWelink. Can anyone provide me a connection diagram for this scenario? I understand that the live status of the switch won't be updated properly if we combine it with physical switches. I'm okay with with that. E W said almost 2 years ago. Varun Thomas Aprem said almost 2 years ago. If I'm going with the second case, then both the switches should be on to power on the light.

Isn't it? I just tried the first option using interlock with my 4ch pro and the physical switches are not always properly turning on and off the light. For trying out the second scenario, would you mind explaining what how to do connect my 4ch with it? I'm finding it hard to understand.Forums New posts Search forums.

Thread starter zippy Start date Jan 11, Joined Apr 24, Messages Hi guys! Hope everyone is well. I hope im not repeating this questionbeen breaking my head over this and I cant figour it out. So im looking into getting these sonoff Mini devices for some of the switches at home to control the lightsI like the idea of this new device in that it can hide behind the switch and I could still use the switch normally from the wall as well as from my phone.

Now heres the where im confused.

sonoff mini circuit diagram

So this is a two way switch each with one button on them Can I connect the Mini to one side and will it allow the other side to work as normal? Do I need a Mini for each button? Or can one mini be used for all three buttons on the switch panel?

Will it allow me to individually switch on and off each button? If that's possiblehow is it all wired up?

Thanks guysHope I made sense. Any assistance would be greatly appreciatedIm trying to understand how the system works before I take the leap and purchase the mini.

After closing up the housing you can use it as before, only with the difference that your modified version only can handle up to 35V DC : Enjoy it ;D. Question 4 days ago on Step 4. Awesome mod! I have a question regarding your choice for capacitance values. The datasheet has a reference design that seems to require much higher values.

Can you provide any comments so I can understand? Looking forward to modding a couple of Sonoffs but wanted to clarify so I can order the right parts. Reply 5 days ago. I actually have the same question. In irrigation systems you find it often 24VAC valves that you need to switch.
