It could be an idea, but I already have my MIM dongle and successfully capturing the communications between the original dongle and the AC.
The big issue is that the original dongle is not actually a USB device, they chose to use a USB-A connector, but the signaling is actually TTL level. I chose to use an ESP32E processor in order to support ESPHome, and enable Bluetooth provisioning of WiFi for ease of installation. I am about 80% complete now. Soon I will be looking for volunteers for testing.
Alas, I tried connecting the homemade dongle with the standard one, but it didn’t work. They conflict with each other. If Dave solves this issue, it can be considered a victory over the corporation TCL)))
"I will gladly participate in testing. I hope the article I referenced above will make it easier to complete your project, and we all get a finished solution without compromises. Good luck, Dave.
Replacement dongle built and being tested now. So far, only 1 small issue that was pretty easy to resolve. Works well with my aircon. If your aircon has this dongle:
If your dongle model number matches and you would like to help test then DM me (and also include your country so that I can check on shipping availability).
Already regretting buying TCL for the lack of HA integration. TAC-12CHSD/FBI are not available for Tuya pairing only TCL Home app. Anyone managed to add these?
Hi dave, I would also like to be a beta user, I have the same wifi stick and would like to try it out with the esp for HA, would be great if I get an answer from you, best regards
