Support for KE100 (TRV) via H100

[mihai-dinculescu]

Did you foresee write operations to child devices on the hub?

Yeah, I'm happy to add whatever is useful to people.
Unfortunately, I have electric radiators, so I cannot test the KE100 TRV myself.

Can you please execute get_child_device_component_list_json on the hub and paste what's returned for the KE100 TRV here?
The first step is figuring out which is the operation that you need.

This is what I get from get_child_device_component_list_json on the hub:

Object {
    "child_component_list": Array [Object {
            "component_list": Array [Object {

                    "ver_code": Number(3)

    ],

I was actually able to get some working example for reading and writing the TRV values. Any good way to share the code with you? I though used the parameters which are exposed by the child device directly. See the following listing for the data exposed from the device.

Object {
    "at_low_battery": Bool(false),
    "avatar": String("kasa_trv"),
    "bind_count": Number(1),
    "category": String("subg.trv"),
    "child_protection": Bool(false),
    "current_temp": Number(20.7),
    "device_id": String("REDACTED"),
    "frost_protection_on": Bool(true),
    "fw_ver": String("2.1.0 Build 221209 Rel.102225"),
    "hw_id": String("REDACTED"),
    "hw_ver": String("1.0"),
    "jamming_rssi": Number(-107),
    "jamming_signal_level": Number(2),
    "lastOnboardingTimestamp": Number(1697277340),
    "location": String(""),
    "mac": String("AREDACTED"),
    "max_control_temp": Number(30),
    "min_control_temp": Number(5),
    "model": String("KE100"),
    "nickname": String("REDACTED"),
    "oem_id": String("REDACTED"),
    "parent_device_id": String("REDACTED"),
    "region": String("REDACTED"),
    "rssi": Number(-18),
    "signal_level": Number(3),
    "specs": String("EU"),
    "status": String("online"),
    "target_temp": Number(17.0),
    "temp_offset": Number(0),
    "temp_unit": String("celsius"),
    "trv_states": Array [],
    "type": String("SMART.KASAENERGY")
}

I'm happy to help out with getting support for KE100 in. Eventually I'm looking to get some support in HA for the KE100 devices and I see this as an enabler for this.

[mihai-dinculescu]

Help will be most welcome!
In that case, it would be best to go through the regular process and get a PR started.

[pwoerndle]

I've created pull request #121 with my initial support for the KE100. The main challenge I have is that the API returns an empty result when setting a device parameter. This currently creates a runtime EmptyResult error.

Released in v0.7.6.
Thank you for this amazing effort!
