Tinytuya - how to turn off/on thermostat

I am using tinytuya to monitor radiator thermostats. It works fine, but after a power failure some of them get confused and don’t report all parameters. Magically, if I turn them off and on using the Tuya app, all is well. So I would like to do this programmatically.

On https://github.com/jasonacox/tinytuya there is reference to turn_off(False) and set_status() methods for tinytuya devices (without any other parameters), and they don’t achieve the result. Wondering whether I am missing something, or whether they maybe are specific to switches or lamps.

This the device model:

        "category": "wkf",
        "product_name": "Smart Radiator Thermostat",
        "product_id": "6rdj8dzm",
        "biz_type": 0,
        "model": "ME167_B",

Thanks for any pointers!
