Smart RF transmitter with rolling code?

[Adeptus Mechanicus]

I'd like to add a few things to my home automation setup and my priority is getting both my electric gates and garage door motor "smartified".

The easiest way to do this, as I see it, given they all operate on 433mhz RF is to add some sort of WiFi to RF bridge but the garage motor receiver is a rolling/hopping code type.

Basically does anyone sell something like the above?

No need to get in the middle of the radio receiver frequency and I don’t believe such a product exists anyway.

Rather just add WiFi to it with something like the Sonoff SV or Shelly and use your phone to interact with it.

We simply bought a remote and wired it to a relay which was connected to a pi zero. The Pi zero I put on our LAN and it ran a simple PHP web app that you could connect to and control - either on the WiFi LAN or over the web. You basically had to access the web site and punch in a code to open the gate. Should be easy to add 2fa to as well.

That is very expensive over engineering when much cheaper products exist to do then very same job much more easily in a single package.

What are you on about?
We did that in our spare time with goodies we had lying around at home LMAO. Oh, and we had fun doing it...

Sorry it meant to read very expensive.

If it cost you nothing that’s fine and good, I’m just pointing out it’s not a great solution to be punting overall as it’s horribly expensive to implement over made for purpose options that integrate into other systems easily etc.

It’s also a very large form factor.

I doubt the sonoff sv is much smaller than a pi zero.

Yeah looking at it now it’s not a massive difference.

But it’s still quite a bit more expensive, doesn’t come with the relay built in and needs considerable work to integrate with home automation systems.

The Sonoff SV can work completely stand alone and use its own app or integrate with smart platforms out the box.

It also powers from your garage motor directly which the Pi does not.

So once you add all those extras it does consume quite a bit more space and fiddlyness.

I agree with just using a sonoff sv
