Hi Bond team, I’m trying to improve support for a Harbor Breeze / Saratoga-style ceiling fan (remote FCC ID A25-Tx007R1) controlled through a Bond Bridge. The physical remote appears to match the `L2` template, but some extra RF commands exist that are not exposed by that template. [A Home Assistant forum user](https://community.home-assistant.io/t/i-found-some-extra-rf-codes-for-my-harbor-breeze-saratoga-ceiling-fan/672764) discovered additional RF commands for this fan family, and I confirmed them on my receiver. The useful ones are: ```plaintext 0000 / 0001 = light off 0010 / 0101 / 1001 / 1101 = light toggle 0100 = brightness down 1100 = brightness up 1110 / 1111 = fan off ``` There does not appear to be a true discrete light-on command. Brightness up/down are relative commands; if the light is off, either one turns the light on at minimum brightness. The default L2 template works for basic fan/light behavior, but it does not expose directional dimming controls to integrations like Home Assistant. I experimented with other templates and found that RCF161 is a much better model: ```plaintext SetSpeed 1/2/3 ToggleLight StartIncreasingBrightness StartDecreasingBrightness ``` After creating an RCF161 device and assigning the learned RF payloads to those commands, Home Assistant exposes the controls much more naturally. The dim up/down commands also needed reps: 1000 since they are momentary controls. My questions: 1. Is there a supported way to define a custom template locally or through the API? 2. If not, is there a supported way to list all available built-in templates and their action/command models? 3. Is there a recommended way to request that a new or existing template be associated with a fan/remote profile? 4. For receivers like this one that support relative brightness up/down but not absolute SetBrightness, is StartIncreasingBrightness / StartDecreasingBrightness the intended action model? 5. Is there a way to update an existing template to add new functionality? I found template names like `RCF161`, `RCF142`, `RCF98v2`, and `RCF118` by experimentation, but I’d rather avoid relying on guessing internal template IDs if there is a documented or supported path. Thanks!
