NOT AN ISSUE: Bseed switches unsupported protocol #229

Open ovid-io opened 3 years ago

ovid-io commented 3 years ago

Hi,

First of all I want to thank devs for putting so much effort into this integration, I have configured 10+ various tuya lights and switches and everything works like a charm!

Only stuff I have not integrated so far are these switches that I bought almost two years ago:

I've quite a few of them and I suspect they are running a different protocol than 3.1/3.3 When I try to add one the protocol automatic selection stays blank:

If I try with protocol 3.1 I get the following error in UI and HA log:

UI: An unknown error occurred. See log for details.

With protocol 3.3 I get the following errors in UI and HA log:

Local key etc. should be correct as I obtained then via tuya-cli and every other device worked. I suspect it could be protocol 3.2 or lower and there is no update for these switches via tuya app.

Is there anything I can do to investigate further/facilitate someone to do it? Unfortunately I've no dev experience with python but am full time node developer.

If you use tuya-cli, can you check that you can get DPs from it ?

tuya-cli get --ip 192.168.1.163 --id 63226301c44f33cdb908 --key 141f2e4e6e74e77c -a --protocol-version 3.3
ovid-io commented 3 years ago

Above just gives me "data format error" and "Error [ERR_UNHANDLED_ERROR]: Unhandled error. ('json obj data unvalid')" with protocols 3.3 and 3.1 respectively

Edit: with 3.1 it seems to timeout waiting for response:

json obj data unvalid

nse from device id: bfbd0e01ac7ba66218ou68')

But it also does same with lights and switches that do work with localtuya so not sure what the deal is there

test.py gives same results:

When pytuya logs data received, this is the data that it receives:

If you enable debug logging, you will be able to see the discovery messages which include the version. That way we can conclude which version it is. We currently don't support version 3.2 and I haven't found anyone else supporting it either, so at this point we're stuck unless you want to help figuring out how it works.

@postlund I've got the same issue with two bulbs that were working before I went into holidays.

This is the debug when selecting 3.3 protocol:
