Brilliant Smart Elite Glass Wall Switches

-
I purchased one of these Brilliant Smart Elite Wall Switches which arrived today. 




I quickly pulled off the front glass panel and could see the upper surface of the low voltage board. 

Fortunately the low voltage board was easily removable, revealing the high-voltage board beneath.
The low voltage board containing the ESP8266 chip on the underside is below. There were a set of header pins which extended into the mains voltage part that I hoped would offer an easy solution for flashing.  

The ESP8266 in this case is on an TYW3ES module which I think is commonly used in Tuya gear. Looking at the TYW3ES data sheet I was able to identify the pins on the module.

 I then did some continuity checks with a multimeter and was able to identify the VCC and GND pins on the header, but unfortunately not the TX or RX pins.

 I connected the VCC and GND pins to a 3.3V power supply using dupont cables, and the board came to life. Note that the red cable is VCC and the brown is GND.


I was then able to flash it with Tasmota using Tuya Convert 2.0. Thanks to the amazing contributors to both of those projects for their incredible software. They continue to impress me every time I use them. Please consider making a contribution to their projects if you find them as useful as I do.

Now I need to figure out how to configure Tasmota to get the switch working...

UPDATE: You can read how to configure this switch in this post.

    Hi, I have the same board and manage to get it to life, however I need to flash it using usb2serial and I have to find the ttx and rx pins, how did you flash it? through wifi? is there a way to use the tx rx on the board withoutt solder?

Smart Irrigation Controller with Tasmota and Home Assistant

I've recently been working on a smart, wifi-enabled irrigation or watering controller for my garden, and have finally got it up and running. I'll start with a picture of the finished product, so you know where this is heading. I had a few ideas for how to achieve this, and over the last few months I've been examining different options, and recently took the plunge and purchased some hardware. I've been doing a number of projects with ESP8266 based hardware, Tasmota firmware, and Home Assistant and so it was inevitable any solution I put in place would feature those elements.

Controlling Samsung Air Conditioner from Home Assistant

-

I've gradually been connecting as many devices as I can using Home Assistant. One of the things that has been on my list is our WiFi connected Samsung Air Conditioner. It is a Samsung model AR24FSSSBWKN sold in Australia in around 2015. We have made use of being able to control the air conditioner using the Samsung Smart Air Conditioner Android app , but it has always been problematic. It consistently requires a username and password to be entered when using it outside of the home, recently it has stopped working inside the home, and it also requests some (in my view) unnecessary permissions (such as telephone and contacts). So, the idea of being able to control it via Home Assistant is appealing. I'd considered trying to set something up with my Broadlink IR Pro  to control it via IR, but most of the possible solutions seemed a bit clumsy. I became aware of the climate_ip custom component for Home Assistant  created by SebuZet who is active on the Home Assistan

Brilliant Smart Ceiling Fan Remote in Home Assistant

Image
A few months ago I purchased a Brilliant Smart Ceiling Fan Remote or Controller , with the intention of flashing Tasmota on it, and setting it up in Home Assistant . I needed to replace a ceiling fan in our lounge room, and so I also bought a Brilliant Tempest II ceiling fan , which I understood should be compatible with the fan controller. You can see a few photos below, but unfortunately I forgot to take any before I had disassembled the parts, so you'll need to check out the BrilliantSmart product page to see photos before disassembly. Here is the box... And the control panel with the cover removed... And the controller, also with the cover removed... Fortunately, thanks to some very   helpful   posts  and investigative work from sparkydave , thecubical and exxalmate  and posted on the  Australia - Electrically Certified Hardware thread  on the Home Assistant forums , I knew that this was a Tuya based device, with a secondary microcontroller unit (MCU).
