Coming from a first time flasher (sounds corny), I use FTDI and ArduinoIDE, maybe it's a bit too much but I'm on an iMac.

1) FTDI chip, I use the CP2102, make sure you get the IC? chip in a diamond-shaped format.

2) Get all your libraries and ArduinoIDE and Tasmota updated to the latest version.

3) I didn't have to solder any of my Sonoffs, but a word of caution, I have only Tasmota-ized Sonoff Basic, TH16, POW, T1 (2 gang & 3 gang), Sonoff 4Ch and Sonoff 4ChPro. So that is my only experience.

4) The toughest of them all was the 4ChPro, because I have to hold another jumper cable from the GND slot to the 2nd pin on the IC. But it can be done.

Anything can just ask. I only followed DrZzs videos, and the Tasmota wiki page. All is there, just that it's technical on the wiki whereas DrZzs is more visual. I'm a visually inclined person.

Home Assitant? are u refering to Google Home Assistant?

I brought all the kits.

But I don't have the time to do. 

you want to flash them for what? whats the purpose actually har? 

play2 only

Has anyone tried controlling their Autogate (DC Motor) with RM Pro? I tried to get RM Pro to learn the signals, but I noticed once learnt, the command can only be used once and subsequently it doesn't trigger the auto-gate anymore. I'm suspecting that there's an algorithm built into subsequent signals, which carries some random number that's only known between the sender (remote), and the receiver (gate control box).

Am I the only one?

I would like to use aqara wall switches that does not use neutral line .

My other option is to use broadlink TC2 or Chuguan.

Auto gate normally use rolling code.
Not suitable for RM Pro.
Rolling Code

All hail the Master Flasher (pun intended)!
Can describe what u are using the different Sonoffs for?

Google Home is the speakers.
Google Assistant is the voice AI.
Where got Google Home Assistant? 
Refer here for Home Assistant

Thanks for your speedy response. Looks like I've hit a road block then

Sonoff Basic just for standby, if suddenly I need to smartify any dumb electronics, can ask the electrician to splice it into the wires.

Sonoff POW for smartifying the washing machine. Base on the power usage, hopefully I can guess when the washing is done.

Sonoff TH for attic fan, if it get's too hot, the fan switches on.

T1 for switches inside the house that I want touchless. And FYI it's a new built, so I wired all with the Neutral line.

Brought 2pcs sonoff sv.

1 for project that use ewelink. Later I post here.

1 more to flash it and play around. See the tasmona and the apps how good is it.

I believe most of the autogate is using momentary switch to trigger open/close gate, therefore, what you need is a normally open (NO) type relay that act as momentary switch.

I have a z-wave 12V DC NO type relay, and through smartthings device type handle, I customized it to become momentary switch, and I  connected the z-wave relay to the autogate PCB connector that connect to normal autogate switch, and it works perfectly.

sonoff relay is a good relay, but it cannot be used in autogate as momentary switch, because the relay input is 240V AC, when it turns on, the relay connect the 240V AC input to output, then it will fry the autogate PCB!

I think you need this - https://www.itead.cc/smart-home/inching-sel...ess-switch.html

But what’s the purpose? I don’t really understand cause your autogate already comes with a remote

Nowadays everything has to be using smartphone. Otherwise, no smart 

SV can flash OTA with Tasmota if firmware is 1.55.

SV and Basic should be the same. Just SV have more choice of voltage to apply and aim for project.
