Soft bind a Sonoff T2 switch to 2 Sonoff Basics

Configuration

Dear all,

First of all I would like to say thank you for the hard work everyone has put voluntarily into this project. I have been following Hass for a long time but it was not until recently that I decided to get involved and help my parents build a better/smarter home as they re getting older and need a few things automated.

HA is running in virtualbox on a Dell R410 (yeah I know, kinda overkill), but it is an always on server that lives there and serves entertainment purposes too.
I have already setup a simple dashboard for their garden lights (1500watts in total) with 2 Sonoff Basics connected to two power relays in a separate switchboard I purposely made for this project.
I used AlexxIT’s method and everything was setup perfectly.

My problem is that they still want a way to locally turn on their garden lights, without using the dashboard.
One way would be to butcher up the Basics, solder two wires to the onboard switch and run them down, about 20m (60ft) to an appropriate location in the house.

My question is: Is there a smarter way to do that?
As I do have a couple of Sonoff T1 and T2s lying around, is there a way to soft bind (I mean through HA) the wall switch to the basic switch?

I m sorry if this a noob question, but I ve read so much these past few days, I feel I m more confused than educated.

Thank you so much in advance.

P.S. As Alexx’s script is quite new, I can confirm by the way that T1 and T2 wall switches (european editions) were immediately discoverable and work perfectly.

I m replying to myself here.

I managed to do it with Automations. Writing two automations (one for on and and for off) doesn’t sound smart. Is there a way to combine it into one automation?
