Hi there,

I'm afraid, the DDF requires some significant changes to be considered. The suggested file would be barely functional.

The battery reading and checkin is missing:

The defaults for this item are tailored for temperature measurement sensors and hence, will not work here. Please replace it by the following:

Please investigate which modes are supported by the device. The code below must be amended according to the findings:

In order to make use of the config/mode item, the following code must be added and contain the actually usable settings (see respetive item comment)

"meta": { "values": { "config/mode": {"off": 0, "auto": 1, "heat": 4} } },

Please remove the default value and add "refresh.interval": 3660 instead.

@fox34 are you still here ?

fox34 · 2024-01-10T20:02:04Z

I made the requested changes, however:

Please investigate which modes are supported by the device.

How would I do this? The device can be toggled between automatic and manual operation (and turned off, obviously). Automatic mode can (only?) be configured in the "official" SONOFF app, which I cannot use because I do not own the SONOFF gateway.

Yes, it's fine, just check wich one mode you can use on it.
From Z2M they are using same

.withSystemMode(['off', 'auto', 'heat'], ea.ALL, 'Mode of the thermostat')

And they have too problem with the "auto" mode, it seem this device don't use zigbee classic request, and use instead a personnal one > Koenkk/zigbee-herdsman-converters#6443

And BTW, they have too found some others request on the special cluster, for exemple can try


                {
                    "name": "config/locked",
                    "read": {
                        "at": "0x0000",
                        "cl": "0xFC11",
                        "ep": 1,
                        "fn": "zcl:attr"
                    },
                    "write": {
                        "at": "0x0000",
                        "cl": "0xFC11",
                        "dt": "0x30",
                        "ep": 1,
                        "eval": "Item.val ? 1 : 0;",
                        "fn": "zcl:attr"
                    },
                    "parse": {
                        "at": "0x0000",
                        "cl": "0xFC11",
                        "ep": 1,
                        "eval": "Item.val = Attr.val",
                        "fn": "zcl:attr"
                    },
                    "default": false,
                    "refresh.interval": 84000
                },
