Don't quite understand your situation
Why do you need a smart switch for the water pump? Normally the pump switch is left turn on all the time.
It has a buildin pressure switch and the pump doesnt run until you turn on a tap.
Dont tell me every each time you want to use water you will turn on the switch for the pump?
Your pump will say bye bye in no time.....

Didn't your water pump auto-triggered by pressure?

probably he think he can switch on and off  like water heater. I saw a guy put sonoff basic at water pump and use schedule, don't know why maybe want to save some electric bill, I guess

Because his pipes are leaking a bit so it turns on the pump.
That’s why he uses a sonoff to turn it off at night. But the basic is only 10amps. I would rather use the higher 16a just to be sure.

Hows your bathroom lights? Got turn off while taking shower? 

Sonoff T1 max is only 2A per gang.
Since you still want a manual switch, maybe can consider Sonoff RF with RF wall switch
Sonoff RF

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. 

Please try and let us know. I forget to put in the link with the RF wall switch.

Sonoff RF with RF wall switch

Like some one suggest pair it with PIR sensor and RF bridge, it will  be fully auto, no need to give remote to your mum.

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?

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.

For Aqara's Double Wall Switch ZigBee version (connected to Gateway), if one of the switch is unused and not wired - can we still program it in Mi Home to open any existingly connected Smart Home devices (i.e. Yeelight)?

Cannot trace the leak location? Wall don't get damp? 

Can

Thanks! Will just get the double (Wall) switch then.. although only planning to wire one of it. The another button keep as spare / control existing Yeelight.

Wei, why u quote me? I am not h11g lah. U baru bangun tidur ah?

Hi all! I'm currently working on my new home renovation project and I had decided few months back that I'll go with Xiaomi's ecosystem. Most of it are pretty straightforward (smart lights, gateway, sensors connected to gateway etc.) but I'm very confused with this two switches, hopefully they someone can shred some lights for me

Am not sure if I understood the items correctly, but both can connect to Mi Home via Gateway, And with that, does it mean that both switches can be programmed directly in Mi Home to set up rules such as
- single press / double press / long press
- to turn on / off any smart devices connected in Mi Home
- to play sound or doorbell in gateway
- to enable security alarm mode
- etc.

This lists price I bought from shopee

You’re welcome
Btw even when both buttons are connected, you can still control one more function by pressing both buttons  simultaneously but the individual wired buttons would also toggle unlike the wireless remote switch

Both the switches in your links have newer versions with more functions
You can get the new wireless remote switch from here - https://aqara.tmall.com/shop/view_shop.htm

The new mini wireless doesnt seem to be available at that store - try ask them

That's interesting to know. So basically wall-switches are kinda like 2-in-1? It controls the hardwired Light + any additional programmed function on its button?
