Today i got a MHCOZY TH1CH-B1RF and installed tasmota:
Users can add the device to the APP eWeLink in order to remotely control connected home appliances or devices. In self-locking mode, customers can remotely turn on/off connected devices immediately. When in inching mode, customers can have two wiring ways to select: * Turn on 1s and then auto-off,* Turn off 1s and then auto-on.
Of course you can stay with the original software, but then you have to
integrate EWELINK to you enviroment (which uses port 5353 with some
strange multicast mechanism). I want to get the values via HTTP. So the questions is: Can this hardware run tasmota?
If you open this device, you see, that the chip is a PSF-Bxx:
With knowing that, Tasmota can be flashed onto this device:
(all the connects are a little bit tricky, because there are no plugs and you have to constantly touch the contacts with the pins)
- Connect GPIO0 with ground (you can use the shielding of the USB connector on the board)
- Insert power via the USB connector
- after 5 seconds remove the connection from GPIO0 to ground
- connect your serial programmer TX --> chip RX
- connect your serial programmer RX --> chip TX
(i always start with TX --> TX and RX --> RX, which is wrong 🤐 ) - open tasmotizer.py
(for installation look here - i chose option 2) - if you choose "backup - save original firmware", then you have to start after the backup with step 1 again.
- choose "release" and "tasmota.bin"
- click "Tasmotize!"
After a reboot change to the new Wifi "tasmota....XXXX" and enter your Wifi credentials there on 192.168.4.1. And after a reboot you can open the web GUI like this here:
Now i can get the values via
curl 'http://192.168.178.107/cm?cmnd=status%2010&user=admin&password=XXXX'
