guys a noob question here, if we use a mix of aqara and sonoff switches can we linked them together to google home?

ok cool

also aqara switches doesn't need N line right? that's the main difference between sonoff and aqara right?

Guys this is the wiring for my water pump, may i know which is Neutral? a bit confused since there is 4 wires instead of the normal 3.

hi thanks for your clarification, so in my case if i want to turn it "smart", which smart switch should i use?

i want to be able to turn on/off the water pump remotely, set a schedule for when to turn it on/off, and maybe in future link it to a motion sensor to turn on the pump when someone is in the bathroom, and turn it off 5 mins after when there's no motion detected.

my water pump is 1.5hp grundfos multi stage pump, so i think it uses lesser than 20A. If i get a Sonoff POW how do i wire them to the sonoff? since my switch have 4 cables. this is how my existing switch looks like.



Is the black wire neutral and yellow wire live?

thanks for all the detailed suggestion guys, really appreciate it. But my water pump is on the roof of my house, and it is situated in a sheltered area but heavy rain water may get to the water pump area. and i'm not too sure about the wifi signal there. my second problem is my mum doesn't know how to turn on the water pump using the app, so that's why im considering the smart switch instead because she can use the switch to turn on the water pump whereas the rest of us can control the water pump on the app. Since my water pump only uses roughly 5amps, means i can use sonoff t1 switch right?

I live in a old house, and water pipe is leaking. So to prevent water from leaking we turn on the pump only when we are using the bathroom, turn it off when not in use. The cost to repipe the house cost a lot of money, so by automating the water pump with smart switch, save us a lot of hassle of turning on and off the pump manually.

Hi, this may be just what i needed. I can give my mum the remote while the rest of us can turn on/off the pump using the app.

this is essentially same like having a rf remote control right? just that it is a rf wall switch instead. Is it battery powered and can be mounted everywhere?

PIR sensor is connected through wifi isn't it? what's the usage of the RD bridge?

Water leak mostly on the roof, wall pipe leak happened before and have to hack the wall to repair the piping, the leak happens very frequently like once every 3 months.

guys this switch is for my water heater. it uses 10 AMP and want to know which sonoff switch is suitable since this only have 2 live wires and 1 neutral?

i measure with a amp meter, max amp is 10A

im running on solar heater, this switch is to turn on and off the heating for solar i think.

normally we only use the heater between 6pm-12pm, so just thought of automating this instead of having to turn on and off everyday.

i am currently on solar heater, this switch is to turn on and off the heating. during hot days dont have to turn on this switch, but rainy days need to turn it on for hot shower. solar system auto on when shower?

What's a SSR?

i dont know where the neutral comes from, from the image, the black wire is neutral right? and the 2 blue wire is live. If i use sonoff pow, can i just wire one live wire and for the load side, i connect both live and neutral? will the switch work like that?

thanks for your suggestion Zot, I will use sonoff POW and wire only L for load, and neutral and L for input side.

Also thanks to this thread i've successfully installed a Sonoff RF to my water pump. I've used the loop timer to turn off the water pump automatically after 20mins, but sometimes it'll turn the pump off within 2-3 mins of the pump running. Anyone facing this issue and possible way to rectify it?

yeah i setup the loop timer as per this video, i've set it to turn off after 20 mins but sometimes itll turn off randomly in 3-4 mins which is way earlier than the 20 mins set.

im using sonoff rf for my water pump, for my water pump N is used.

I've figured out the problem. Sonoff doesnt support automatically turning off a switch whenever it is turn on by any means. the loop timer is not smart, it just creates a loop and that's it. I guess i need a home assistant to do the automatically turn off after certain minutes whenever a switch is turn on.

yes because it just follows the loop. but what i want is for the device to turn off automatically after 20mins. so what app are you using now?
