Converting a Treatlife Smart Ceiling Fan Control and Dimmer Light to Tasmota

Hardware:


1 - Treatlife Smart Ceiling Fan Control and Dimmer Light - ~ $44.99 on Amazon

2 - new plastic wall plate to accomodate UPB dual toggle switch and Fan / Light control dimmer 

Carlon A420 Outlet Box Cover - ~ $5.41 on Amazon

Updating to Tasmota.

 

1 - at this time these devices are shipping with Tuya firmware that is blocking the current TuyaConvert exploit

2 - The switch will need to be flashed via the old school manual method

I've left the above and will continue here with a step by step including wiring and JTAGing of the WiFi switch.

Decided to try a JTAGing jig to update the firmware to Tasmota.  This is a solderless mechanism which allowed updating of firmware via a 3D printed jig.

Here is the TYWE3S Pogo Pin Programming Jig. Very easy to use.

Finished box #1 and working on box #2.

 

Here the steps in Linux to upload the firmware.

 

Steps using ESPTool and command line in Linux. Note that flash is 2Mb in size.

1 - pip install esptool
2 - backup firmware

esptool.py --port /dev/ttyUSB0 read_flash 0x00000 0x200000 image2M.bin

3 - download current version of tasmota.bin file
hxxps://github.com/arendst/Tasmota/releases/download/v9.1.0/tasmota.bin

4 - erase flash

esptool.py --port /dev/ttyUSB0 erase_flash

5 - write flash

esptool.py --port /dev/ttyUSB0 write_flash -fs 2MB -fm dout 0x0 tasmota.bin

6 - unplug and power up board

7 - attach to Tasmota AP and configure Tasmota to your AP.

 

Had issues fitting the two switches in the box.

Moved some wires underneath the UPB switch.
 
Completed configuration.
 
finished switch

First time boot.

 

1 - scan your wireless network and connect to AP labeled tasmota_XXXXX - no password required

2 - using your browser go to IP 192.168.4.1

3 - scan your wireless network and click on SSID that you want your switch to connect to

4 - configure your switch.

 

After configuration type the following in the console.

 

module 54
 
backlog so97 1 ; tuyamcu 11,1 ; tuyamcu 12,9 ; tuyamcu 21,10
 
backlog ledtable 0 ; dimmerrange 10,1000 ; so59 1 ; so68 0
 
Add the following rule, this should be all on ONE line.
 
Rule1 on TuyaReceived#Data=55AA03070005030400010016 do publish2 stat/%topic%/speed 3,0 endon
      on TuyaReceived#Data=55AA03070005030400010117 do publish2 stat/%topic%/speed 3,1 endon
      on TuyaReceived#Data=55AA03070005030400010218 do publish2 stat/%topic%/speed 3,2 endon
      on TuyaReceived#Data=55AA03070005030400010319 do publish2 stat/%topic%/speed 3,3 endon
 
Enable Rule1

No we need to post doing it over Wifi.  I just setup my raspberry pi - just need to find some wire nuts to setup my test switch!

I have Tuya-Convert installed on my Linux laptop from a while ago.

 

Tried Tuya-Convert yesterday and a few weeks back and it does not work with Treatlife Smart Ceiling Fan Control and Dimmer Light.

 

Tuya-Convert has worked on other WiFi switches for me.

 

Per DigiBlur's website The Tasmota Fan Controller I've been waiting for...

 
Unfortunately, at this time these devices are shipping with Tuya firmware that is blocking the current TuyaConvert exploit.  The switch will need to be flashed via the old school manual method.  Don't worry, this is fairly simple.

Yeah, Tuya is actively updating their firmware to patch the exploit that Tuya-Convert uses.  I've been installing Martin Jerry switches over the last couple of months and the first batch I bought I was able to flash 100% of them OTA using Tuya-Convert.  The second batch I bought only 25% of the switches allowed me to use Tuya-Convert.  This last batch none of the switches allowed me to use Tuya-Convert. The switch model has been the same in all the batches.
 
I quickly had to learn how to connect to the device with physical connections and a USB/serial converter.  Luckily I had already bought the converter thinking that I'd end up having to use it at some point, so I didn't have to wait to get one shipped. I like using Tasmotize (which is really just a nice GUI that uses esptool.py to flash the devices).  The ability to send a config file after flashing it is really helpful.  You can set up wifi credentials, MQTT information, and even the template using the config file so that you don't have to log into the "Tasmota-XXXX" wifi and enter your wifi credentials after flashing the device.  You simply power cycle the device after flashing (unplug and replug in the the USB converter), send the config file (which is as simple as pressing a button in Tasmotize), and restart the device.  It will come up on the desired wifi network with the template and MQTT info already programmed in.  It's a real time saver IMHO.

Oh no! Am I going to have to do that with all my switches?! How do I make sure I don't get the latest firmware while I am away from these switches?!

 

Can you STOP firmware?

Can you STOP firmware?

 

If you have registered and are using the cloud app I do not think that you will be able to prevent firmware updates other than taking the switches off the internet.

 

You can speed up the updating (if you want to) a tad by disconnecting the hot lead to the switches and pulling off the esp wifi board and updating the board, testing it for Tasmota and reinstalling the board.

 

I am seeing that more and more vendors are attempting to lock you to their cloud apps.  BUT the most popular WiFi switches are those that you can update firmware too.

While I'm sure Tuya can probably push out a firmware update, I really doubt they would do that.  The chances of the update failing and leaving a device unresponsive is too high IMHO for them to do that.  They are obviously shipping new devices with updated firmware, but I don't think I would stress out too much about getting an OTA update pushed out from Tuya.
