Adding capacitor is for switch without N wire and only required if load are low power device such as LED light as far as I know

No. Sonoff T1 need Neutral wire. It will not work the way it would with switch without N wire.

This is another method. But if someone off the wall switch then can't control already.

For me, it is not about the module used in the circuit but how the circuit is designed to power the module. It is more on the circuit design and nothing to do with firmware. 

Wow this is just what Im looking for, I just bought a sonoff t1 3 gang without realising I cannot use it for my porch light, since most switch dont have neutral lines. This is an interesting solution. Can your friend share the contacts of the electrician that did the mod. The last electrician I talked to told me no choice have to hack the wall and pull a neutral line to the switch.

I tested the basic sonoff on my Xmas lights and thought the wall switch would work the same.

Guys, anyone integrated the sonoff T1 to Amazon Echo? if it's a 3 gang switch, can the voice command control switch by switch? or it will on all 3 switch when you ask it to turn on?
Can configure each individual switch to different names on that one gang?
Thanks!

v4.7.2 and region is mainland

i bought the aqara cam to compliment the 1st gen hub and perhaps to try play with HA, a bit leceh to go buy another one again
BTW is the mi smart socket (non zigbee) compatible with HA?

guys. any alternatives to RM Broadlink that can be controlled by Alexa? ive search so far, none.

I want something that can control both ir and rf. Want it to control my autogate.

I think the thinkings are going to complicated direction 

I believe that any auto-gate for house has momentary switch on the wall to open and close the gate. Why can't just replace that switch with whichever remote switch?

from what i gather at the moment, it seems that u will need to have the xiaomi IR round transmitter first, then the receiver which comes in both formats (box or usb dongle) contains the RF antenna which will do the last mile communication with the RF device.

xiaomi IR -> IR/RF converter -> RF receiving device (auto gate).

during purchase, u will need to specify the receiving device frequency (433 / 315 / etc Hz).

now comes the tricky part which i don't quite understand yet. the description claims that the product can learn the RF commands of the device it is controlling, but not sure how this can be done.

For autogate control in the market, is there a common set of standard command that the RF remote uses which this product can just replicate?

the copier autogate remote available on the market is a simple setting. it can copy without any configuration. but yes, u need to be aware of those RF frequency. Ive 2 gates, both using different frequency. thus i need an item that can support both frequencies.

problem with broadlink, only the old one can be controlled by alexa through RM plugin. the latest one u cant even detect the plugin and thus u are stuck with alexa broadlink skill which can only control IR to control your TV. to know what version u used is difficult.

I use HA, hassio to send out script in squence & delay time in between sequence. Will share part of the configuration.yaml once im at home.
It turn on TV & my hypptv box (until it enter channel)

The last command “exit” for hypptv to remove the lower row of menu is cacat abit & need to delay further. My timing to deliver exit button RF package is slightly faster d

Flash custom firmware means will connect to different server?
If different server, how the smartphone app going to talk to the Sonoff?

Home Assistant even offline you cant control from app. Only from your pc

For the xiaomi cameras, can you set specific time of the day to record and alert you when a motion is detected? For example 7AM to 6PM only. Any other time out of this range will stay silent (although camera is still in operation).

Guys How do i configure the HA ios app? Im not sure how to get the url and password. Been using the web interface since i got started recently - hassio.local

anyone using sonoff products?

how to be self-reliant and not use their servers?
