Problem description

Here is the signature for it:

{
"node_descriptor": {
"logical_type": 2,
"complex_descriptor_available": 0,
"user_descriptor_available": 0,
"reserved": 0,
"aps_flags": 0,
"frequency_band": 8,
"mac_capability_flags": 128,
"manufacturer_code": 4417,
"maximum_buffer_size": 66,
"maximum_incoming_transfer_size": 66,
"server_mask": 10752,
"maximum_outgoing_transfer_size": 66,
"descriptor_capability_field": 0
},
"endpoints": {
"1": {
"profile_id": "0x0104",
"device_type": "0x0051",
"input_clusters": [
"0x0000",
"0x0004",
"0x0005",
"0xed00",
"0xef00"
],
"output_clusters": [
"0x000a",
"0x0019"
]
}
},
"manufacturer": "_TZE284_ymldrmzx",
"model": "TS0601",
"class": "zigpy.device.Device"
}

Please let me know if there's other information required.
I'm happy to test this.

Datapoints: https://github.com/Koenkk/zigbee-herdsman-converters/blob/db7595cf52b55ff47c2132d0952d7444cc0f1b91/src/devices/tuya.ts#L5295

Thank you @prairiesnpr!
Is there a guide for how to add this to my Home Assistant instance?
Is this done or is there more dev required?

Thanks!

[prairiesnpr]

Sorry, in a hurry and wanted to capture the datapoints. That's for z2m, we can use it as a guide to build the ZHA support. If you want to get started, look at the Tuya docs and wiki in this repo and the existing trv quirks in tuya_trv.py. That would give you a baseline on how to build a quirk.

[tomblu88]

Honestly, I don't know where to begin. Any help would be appriciated!
I'm happy to test the quirk on my instance and share with the community.
Thanks again!

This is about as far as I got with the help of Copilot and ChatGPT, but it doesn't work and I don't know why.

That's taking you in a bad direction. You want to do this with TuyaQuirkBuilder. Start with an example from tuya_trv.py and slowly add Datapoints.

@tomblu88 See if #3819 works for you.
