device support

[bkbartk]

Hello,

I don't know it this is the place to ask, I was looking for some kind of Q&A page or message board but couldn't find any. Are there plans to extend the device support to other devices as well?

there are 2 devices which I want to OTA flash, but I'm a little bit afraid I will kill the functionality if I don't know the config. I'm especially interested in vacuum cleaner support. this makes use of datapoints over tx/rx instead of GPIO pins. So I don't even know if this is possible,

but the main question is, do you have plans to support more device types if possible?

What other devices specifically do you mean?

The vacuum cleaner, does it have BK7231? These usually have something more powerful, even Linux sometimes.

"datapoints over tx/rx" is simply TuyaMCU. UPK2ESPHome supports TuyaMCU (partially), so you can try that.

specifically I mean vacuum cleaners, Also doorbells, but those mostly run linux busybox, so It might be another challenge.

I actually don't know for sure, I was expecting it to be Either BK7231 or ESP8266 since my model is from 2021. Is there a way to know this without opening the device? I the tuya app the firmware says:

Main Module: v2.1.6
MCU Module: v6.0.1

not sure if it's possible to derive the chipinformation from here, Or maybe I should just try to use cloudcutter and see if it works.

true, but if it doesn't work, my vaccuum cleaner will probably brick, however, I found this one, https://github.com/Rjevski/esphome-eufy-robovac-g10-hybrid So I could give this approach a try if UPK2ESPHome won't work, But I was hoping it would be easier to have something autogenerated to avoid mistakes.

@bkbartk maybe you can check if the vacuum cleaner is here listed https://robotinfo.dev/, if so it's possible that you can use Valetudo https://github.com/Hypfer/Valetudo

What's the manufacturer / model?

[bkbartk]

My Vucuum cleaner is not listed here, It's a "Medion S20 SW" (Purchased in The Netherlands) I can try this but to have it off cloud I use "Local Tuya" and block all internet traffic from the device. The only thing not provided here is cleaning records.

I tried Cloudcutter but it doesn't work, so the chip probably is not Beken.

You can also try to get the vendor name using the MAC of the device and some web pages like this https://www.macvendorlookup.com/

If you're lucky, you'll see something like "Beken Corporation", if not only "Tuya Smart Inc."

[bkbartk]

unfortunately I'm not lucky however, I do see Tuya is an American company

this gave me an idea, I checked a tuya device with an ESP8266 chip inside, it says: Espressif Inc. And one with a beken chip inside, it says:

Company
    Tuya Smart Inc.
Address
    FLAT/RM 806 BLK ? 8/F CHEUNG SHA WAN PLAZA 833 CHEUNG SHA WAN ROAD KL
    hongkong Hong Kong 999077
    CN
Range
    70:89:76:00:00:00 - 70:89:76:FF:FF:FF
Type
    IEEE MA-L 

also tuya, but a different address and range, so at this point I can rule out that an espchip is inside.

[edit]: another check on a tuya device whic runs linux(doorbell with camera)

Company
    AltoBeam (China) Inc.
Address
    B808, Tsinghua Tongfang Hi-Tech Plaza, Haidian
    Beijing Beijing 100083
    CN
Range
    84:7A:B6:00:00:00 - 84:7A:B6:FF:FF:FF
Type
    IEEE MA-L 

so at this point there is still a possibility a beken chip is inside
