LAN API Support

[linkian19]

Is your feature request related to a problem? Please describe.
Many Govee Devices support control via their LAN API protocol which allows 3rd parties to control Govee devices locally. Supporting this feature would allow users to control their devices locally without having to rely on a cloud solution.

Describe the solution you'd like
I would like to see the following solutions:

1. The LAN API connection to the device should be preferred if the device supports it. Only fall back to AWS IoT MQTT and Platform API as needed.
2. An additional entity per device that displays the current connection type (LAN API, AWS, Platform API, etc)
3. Documentation and/or logs should clearly state the requirements needed to enable LAN API use.
4. Ensure that the integration can/will traverse all configured network interfaces on Home Assistant for discovery in order to support users who have multiple NIC's set up for Home Assistant (I am one such user).

Describe alternatives you've considered
The current alternative that I am using is the following Home Assistant app/addon: https://github.com/wez/govee2mqtt

As far as I am aware, since I am using it, it marks off all of the above 4 points I've made. It prefers to use the LAN API when possible, if I view the Web UI it provides it clearly states which connection each device has, it outputs logs of detected devices and if it can connect via LAN API or not and will let you know if the device SHOULD support it. And it also has settings for configuring how to traverse networks.

Additional context
I realize that I am asking for you to implement something that technically already has a solution but I appreciate how responsive you've been on this integration and how you've begun to add BLE support, which is something MANY of these Govee custom integrations lack. Having a complete "One Stop Shop" integration is very appealing to me.

If there is any other information I can help provide, please let me know and I'm happy to provide what I can.

Thanks for all of your hard work!

I would also like to join this feature request, as I would very much welcome a native support of the LAN API in the integration.

Local control offers great advantages in terms of reliability, response time and data protection. Many Govee devices already support the LAN API, so it would make sense to prefer local communication rather than being mainly dependent on the cloud.

I think these points in particular are very important:

• Preference of the LAN API over cloud connections, if supported
• A visible entity or Status display for the current connection type per device
• Better documentation and logging for setting up and detecting the LAN API
• Support for home assistant systems with multiple network interfaces

I also know solutions like govee2mqtt, which have already successfully implemented many of these functions. A similar functionality directly in this integration would make it a much more complete "all-in-one" solution.

Especially now that BLE support is already being added and the integration is actively evolving, native LAN support would be an excellent addition.

Thank you for your work on this integration.

Good morning,

I don't mean to be rude, and I really appreciate the work that went into this integration—it's a great idea and a great setup—but could I get some feedback on the LAN API?
Because right now I'm back to using Govee2MQTT since it's simply more responsive than the LAN API.
With your integration, it also runs via MQTT, but through the AWS IoT Platform if I understand correctly, and that would explain the delay compared to Govee2MQTT.

Thank you very much

@SH1FT-W I don't have any LAN devices I can test with, though I'm almost done with getting all the other issues fixed. MQTT is part of this integration as well, but local LAN is going to require some work and some testing from people to get correct diagnostics. What I'll start working on is a diagnostics script to allow us to collect data for local API access that will help us build this into this integration. stay tuned, hopefully in the next few days

Hey, I'd love to order you an affordable €25–€30 Govee LED strip with LAN support via Amazon Wishlist so you can test it out “better” with our support.
If you'd like, feel free to send me a Wishlist!
Your work deserves support—it's great!

I only have a couple of local LAN devices, but count me in for testing and providing data if it helps. I was using this integration for awhile but went to the other one. Local API is just almost instant compared to the cloud lag and needed it to sync a couple of lamps.
