So I just cracked open a Brilliant fan controller. It appears that the ESP communicates with another chip, STM8S00 or something. My electronics skills aren’t fantastic…
Not sure how to proceed. Any tips for figuring out what I/O would need to be coded into this thing?
I would rather figure out the I/O before I try flashing ESPhome onto it since in its current state I should be able to use it via the Tuya component of I had to… Not sure how possible that is
Maybe settings from THIS post above might help get you there?
You have to set a new config in Tasmota called TuyaMCU to talk to the ESP8266 via UART (I think).
Maybe from THIS onwards as well?
Cheers. I did think something like that had been mentioned. I don’t have any Tasmota experience so this will be… Interesting 
I’ve had too many beers to attempt this today
Beers and coding are fun though.
Watch Tasmota change your life for the better. No more of that ESPhome stuff 
If you configure it as a TuyaMCU in tasmota and do a weblog 4 when you hit buttons on the remote you should see some debug output in the tasmota console.
Now I’m not sure if tasmota allows you to just send those commands directly as most of the existing things are about lights on/off or brightness levels.
Could potentially ask on the github/forums once we have the tx/rx data.
Managed to get ahold one of on the tasmota devs on discord, they are adding in support for these kind of switches currently. See the PR https://github.com/arendst/Sonoff-Tasmota/pull/6735 specifically adding a tuya send command https://github.com/arendst/Sonoff-Tasmota/pull/6735/commits/bde57933bc3cd61b8f14c16e3d20a6fc5661f389
In the mean time it seems that if you do a weblog 5 in console, hit a button on the rf remote and capture the value from the console you can add rules to send it using SerialSend5
Apparently it would be similar to how https://blakadder.github.io/templates/oil_diffuser_550ml.html is configured
Another item worth keeping an eye on. Jaycar look to have recently added a Shelly1 knock-off on their website. It doesn’t look like it has hit the stores yet, but could be the item we’ve all been hoping for.

That’s been around for a loooong time. It’s using the old Broadlink coms from memory. They are running the stock out, they used to be $40.
Old post discussing it…
Bugger. Apologies for the bum-steer.
Hahaha, all good mate. I wanted to get one ages ago to try out, but all the stores nears me had no stock.
I only wish Shelly would cert in Aus so we could use them.
Has anyone checked out the Deta Smart Wall switches Bunnings seems to have now?

Double gang: https://www.bunnings.com.au/deta-smart-double-gang-light-switch-touch-activated-with-grid-connect_p0098812
It looks like the Tuya serial MCU support is in development for ESP-Home now also:

Nice write up, maybe add some more pictures of the board/s. Just to confirm, this switch has 1 input, but 2 outputs.
I had a look at them last week, but wasn’t sure of the quality of the buttons, what are your thoughts on the quality. Are they touch sensitive, or push/toggle type?
This is the cheapest I can find the Brilliant Wall/Light switches currently. $10-$15 per unit cheaper than on JD Lighting, for anyone interested in picking some up.

Tradezone.com.au also has them for a similar price, but you need to create an account to see the pricing.
If you’re talking about the DETA switches, I’ve added some more pics here: DETA Wall Switches
They have a touch sensitive button.
Yep, I was. Thanks for adding more photo’s. It’s hard to tell what the insides look like when in the packaging. What are you thoughts on the quality/feel of them?
Do they feel like a decent thing, or cheap and plasticy? I’m leaning towards the Brilliant switches due to the glass fronts, but these are cheaper, so… 
They feel of similar quality to a standard light switch, in that the plastic is similar. I guess the proof will be when they are actually in use though. I have one of these and a Brilliant switch as well. I’m going to get an electrician to install both of them, and see which works best. At this point I’m probably leaning toward the DETA switches though, because they are similar aesthetically to all the other switches in the house.
Thanks for the pic… interesting that by the looks of the PCB there should also be a 3-gang version.
