    Are there any recommended models of Home Heating Thermostats (Gas) that can be flashed with OpenBeken or similar? Or has anyone flashed one and created a config? This is something I wish to try, as my current Tuya-based unit is rather inflexible with its programmable settings. I would rather buy a new unit rather than dismantle my current one, as I don't wish my current heating to be out of action should the plan not work out.

    Can you share the desired model, link to buy maybe?

    Almost all Tuya devices can be modified to run OBK but some of them require more then just flashing especially new devices never covered before.

    Hi - I was hoping someone else had already done something of this nature so I could just buy that device. This isn't for experimentation or to see if I can make it work; more just to get my current device off cloud and I feel obk is the easiest way to achieve this. So yes, open to recommendations

    Do you think it would be possible to replicate the config listed here:

    But rather than swapping it to esp32 use the installed Realtek 8710c would I be able to replicate that config on this?

    My current thermostat has a wbr3 which is very similar to the one linked above if not the same.

    Most likely but since it has not been done yet it will not be just plug and play.

    I found one on AliExpress and will order it soon to get the sense of what is going on and if it is possible to configure it to OBK.

    No idea what the differences are so feel free to give me a hint which one to get.

    I just wonder if the openrtl supports the DPLDs so I could transfer them over from the Tasmota config. If that doesn’t work out, I can just solder in an ESP32 as they are super cheap

    Screenshot of code section with #define settings for REALTEK platform

    Default release does support TuyaMCU so in theory it should work - again just from my experience - I haven't tested that, maybe @insmod can say more or @p.kaczmarek2 ??

    Can’t seem to find an ME81H that supports gas boilers that will ship from AliExpress, so I think I’ll buy a replacement Minco one from Amazon, and modify my current one, as that’s a Minco one too.

Topic summary

The discussion focuses on identifying home heating gas thermostats compatible with OpenBeken (OBK) or similar custom firmware to replace Tuya-based units with limited programmability. Most Tuya devices can be flashed with OBK, but newer models may require additional modifications beyond flashing. The user seeks recommendations for thermostats already supported or easily adaptable to OBK to avoid cloud dependency. A specific interest is in replicating the ME81H thermostat configuration, which uses a Realtek 8710c chip, rather than switching to ESP32. The current thermostat uses a WBR3 chip, similar to the ME81H. There is uncertainty about OpenBeken's support for DPLDs to transfer Tasmota configurations, with a fallback option to solder an ESP-12 or ESP32 module due to their low cost. The default OpenBeken release supports TuyaMCU, suggesting potential compatibility. Due to difficulty sourcing an ME81H with gas boiler support on AliExpress, the user considers purchasing a Minco thermostat from Amazon and modifying their existing Minco unit. An AliExpress link to a potential device for testing OBK compatibility was shared but without clear model identification.
