Adding a pretty basic light with remote

I have a lamp with a remote that uses 433Mhz. Luckily I have openmqttgateway already set up with 433Mhz transmitters/receivers for some remote switches so I can see the button presses hitting the MQ. The remote is pretty basic - on/off, change temperature cycles through 3 settings, and brightness up/down buttons. What would be the best approach to create this as a light on Home Assistant. It doesn’t have a brightness/temperature setting as you can imagine just the ability to step up/down. I’m thinking a combo of templating and an mqtt light but need a little point in the right direction to work it out.
