we could do with an engine of some sort that will take Tuya json and spit out an autoexec, with some options for customisation before output.

any inspiration in this thread? https://www.elektroda.com/rtvforum/topic4003974.html

this backup + 22m2ytawuenfen5b key in TMDA is the same result as that key with 1st backup.

Thank you, doesn’t look like these dpld values align to me. Id2 is not the set the desired temperature

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.
