Information about how the device functions

This is a wireless meat thermometer. I believe it is a rebranded version of the Inkbird INT-12-BW meat thermometer as the two have near identical specs & design. So if the device can be successful added, I would imagine the configuration for the Inkbird variant would be near identical. The meat thermometer has two wireless probes that each track separate temperature, the larger probe also records ambient temperature.

[ctml91]

I tried adding the device using the other integration Local Tuya and manually setting up entities using DPs. A few of the entities values show the raw values and work as expected (e.g. setting screen brightness), while some show what look like they might be encoded values. I am not sure if that means that some DPs may won't be useable, like for example the two temperature probes themselves which would defeat the purpose of supporting the device if the temperatures cannot be read. Local Tuya refers to those DP values as "cloud pull".

Tuya smart app also doesn't show the human readable values for all entities. Would that a problem to be able to support those DPs?

[make-all]

Encoded values can be decoded if we know the encoding format. Sometimes this is explained (in Chinese) in the Query Things Data Model description fields. Other times we need to collect samples of known states to try to reverse engineer the format.

I'm not familiar with what localtuya labels as cloud pull. It may mean that the value was not available in the local data when they first polled it (which does not necessarily mean it will never be available locally).

[make-all]

Unfortunately everything useful seems to be in binary fields, and the descriptions just have references to some other device specific documentation, such as:

Refer to INT-14-BW access protocol reference [2. Real-time temperature (UUID: 0xFF01)] and note the data validity.

Also, none of the fields documented like that are showing up in the log message, so they may need to be pulled from the cloud as the localtuya message hints.

Thanks for taking a look, that is unfortunate. Is there anything I am able to provide in terms of data that would assist with getting it supported, or do you think it may not be possible?

I believe this device is from the same line as the Inkbird INT-14-BW and INT-12-BW, so probably all transfer data in the same format.

Since the device supports Bluetooth and WiFi, I would assume that there is no cloud dependency to read values at least (but maybe still encrypted for some reason).

[make-all]

If you are able to collect samples of those fields, it might be possible to decode them. Putting the probes into iced water and boiling water is one way to get known temperatures out of them for study.
