Describe the issue

Not sure if this is standard Home Assistant behavior or not but it is my view that when a dimmable light is powered on using the on/off power switch, it should power on at it's most recent load level. When this is done with a Philips Hue light, it is powered on at it's most recent load level. When lighting control is programmed in Vantage, the programmer usually specifies the load level. For interior loads, very seldom is it 100%. It just seems more user friendly to power it on at it's most recent level.

Reproduction steps

1. Go to the HA Dashboard UI and press the power toggle on a a dimmable load from Vantage.

Hey @ddetton thanks for the feedback!

This is something I considered when initially writing the integration, and it looks like it is about 50/50 on if lighting integrations default to 100% or default to the last known state - there seems to be no convention or recommendation from HA.

One quirk of defaulting to the last known state, is that I couldn't find any exposed Vantage command interface for "turn on to last level". You must always specify a load level, eg LOAD 118 100.0.

One way around this would be to always track the last known level in memory in Home Assistant, but this would mean when restarting Home Assistant (eg. for an upgrade) we would lose these cached levels. Given the complexity of tracking/storing the cached levels, I opted to have "turn on" commands default to 100%.

I'm open to alternative approaches here, as I may have missed something!

Hey @loopj , continue to default to 100% but provide a configurable global power on level in the integration. Out of the box the parameter is 100% but it can be changed to another level that would apply to all loads. An additional bonus feature could be to have separate power on level parameters for daytime and nighttime.

This is one of my most heavily used integrations because it works so well. I just discovered the power of vantage task and button events. I have a mix of Vantage and Hue controlled lights. I just programmed an HA automation that is triggered by a Vantage keypad button press to turn off all of the Hue lights in an area. The button already turned off all Vantage lights. Now I don't have to use Siri to turn off all of the Hue lights. Excellent work and thank you for this integration!

Is it possible to consult the entity history that is built-in to HA (I believe it's 7 days?), in order to quickly ascertain the previous load level. Otherwise you need to create a new entity for every load that contains the "previous" :(
