[Bug]: asking alexa to turn on a light to a certain brightness, light comes on but the brightness is not set #790
Description
Version
3.0.0-alpha.76
Matter Controller
Alexa
Steps to reproduce
I have just started testing this after emulated_hue integration stopped working. Mostly it is brilliant, but I have found this one anomaly. If a light is off and I say "alexa set the square light to 40", the light comes on but at whatever previous brightness it was at. If I say it again once it is on, the brightness is set correctly.
In the addon log messages below, I said this twice. First time with the light off, there is an "on" followed by the level setting to apparently the correct level, but the light came on at 100% (its previous setting). I then say it again, there is only the level set this time, and the light responds correctly. This light is a hue bulb connected to a sonoff zigbee dongle on HA.
I have also captured any call_service events in HA in a node red debug node (not the same time as the addon logs, but the exact same sequence). The first turn_on event does not include a brightness value, and there is no separate call for that even though there are "on" and a "level" calls in the addon log. The second time I say it, with the light already on, the turn_on event DOES include the brightness level.
So - whatever the addon is doing when a command including a brightness level for a light that is currently off comes in, that brightness is not making it through to any call_service event that HA eventually issues.
