MSL100D Brightness Error

[Aridor2006]

• Please explain your feature request in a one or two sentences. I can turn the MSL100D On and Off, but whenever I change brightness, nothing happens and it reverts. The log shows a "Not supported type!" error.

• Is your feature request related to a problem? Please describe. Changing the brightness should work.

• Any particular Meross devices that this relates to? MSL100D

• Anything else?

Hi @Aridor2006

This is indeed a strange issue as I thought brightness was sorted for these devices.

What I will need from you is some http sniffing to see how the meross app controls the brightness.

Very happy to guide you through this on discord: https://discord.gg/bHjKNkN

Does this help? It seems to have an additional capacity field, which doesn't change? Attached are the POST requests for changing the brightness to 100% and then back down to 1%.

{
  "payload": {
    "light": {
      "channel": 0,
      "luminance": 1,
      "capacity": 4
    }
  },

Can you update to the beta version of the plugin to see if this has fixed this? https://github.com/bwp91/homebridge-meross/wiki/Beta-Version

This fixes it, thanks!
