Support for 15c (T2120)

[rmountjoy92]

Hello, I've done a bunch of research on how to control the Robovac 15c (T2120) with home assistant and I keep getting pointed to here. I have gotten the localKey and devId from the abd commands - which was quite easy. But when I run the demo I get:

I ran nmap on the IP and it is the correct IP and port 6668 is open. Any ideas of where the problem might be coming from? I'm gonna keep trying to figure it out (mainly because these things dropped to $80 open box from amazon and I bought 3 of them lol) but if someone could point me in the right direction it would be much appreciated!

edit:
When I force closed the Eufy app and reran the demo, the output looked like this:

Just to see, I put the custom component into HA, here's what it looks like (note: I had to leave the model as T2118 because if I put T2120 it says 'unsupported model' and doesn't load at all into HA):

None of the buttons do anything

Here's the logs from HA:

Update:
For some reason, if you change the TuyaDevice default version to (3, 1) in line 438 of tuya.py it magically works 100%.

Thanks a lot that change on the tuya.py work on my 35C. I was looking for a fix for weeks now never had been able to make it work with home assistant till now.

[aptonline]

I'm trying to do the same for the RoboVac 15C MAX but the above change doesn't seem to work. Any ideas?

getting the following error:

EDIT: The demo works as expected.

Leaving the model as T2118 and making the changes to tuya.py proposed by @rmountjoy92 made it work on my side with the 15C on WiFi Version 1.1.1 and MCU Version 1.1.4 on the 15C.
Thanks a ton!

If anyone wants to submit a pull-request to make this more easily configurable, I'd gladly accept it.

@aptonline You have a typo, the line should read:

gateway_id=None, version=(3, 1), timeout=10):

[clarkd]

FYI - I just set up the configuration and it did not working using Tuya (3,1). Reverting back to (3,3) works as expected.

Hi all,

my turn to try get this working, i have tried all the above and still no luck! even tried higher versions.

'utf-8' codec can't decode byte 0xda in position 3: invalid continuation byte' this is what shows up in the log

Anyone else recently done the integration?

thanks

After I removed line 116,117,118 and updated 119 in the vacuum.py my G10 is working now

But I get following error. Did you manage to solve the docoding error?
