rat-ratgdo VS Ubiquiti

You may actually need a little bit of extra information to recreate the little PCB board that the ratgdo software relies on to interface the espressif to the terminals of your opener.

It's not terribly complicated but for reasons that are polarizing to many in the garage-door-automation society, the author of the software, although leaving the code completely open source is averse to publishing schematics for the PCB board itself, so others have had to step in and reverse engineer these.

I believe, although I have not verified because I haven't tried this myself, that this site provides both the schematics you need as well as information necessary to Flash the software onto your ESP device.

Another neat idea is to connect all “smart” equipment to an isolated vlan and separate wifi that can still be seen by your normal network devices.

For example if your wifi was called “Home”, an additional “Home-IoT” is for every device.

The IoT devices can then be set to not sniff your network, or even connect out if you want.

A good example of this is in this EdgeRouter setup guide, which is a pretty decent guide on how to plan a home network for more than just basic home browsing.

One extra step I’ve learned to follow is to verify if needed, could the hardware be permanently redirected to a local server, and worst case reflagged with a different firmware or it can be redirected to remain local. The latter is sometimes easier if it’s a Tuya based device, which a lot of these unknown devices are.

One of the main things these “smart” devices do is use your internet connection. It’s wise to create a dedicated _IoT suffixed wifi which can’t access your network or devices, but at the same time your other devices can ping them.

How?

This is a pretty solid guide of a home network setup here. It can be running a $50 EdgeRouter X or translated to other devices.

I followed this guy on Youtube and this guide on github to set up an Edge Router X. It was cheap and does all this, but was harder than I thought it would be to set up, even with a video guide.
