Automation that translates percentage into seconds (runtime) and remembers state

Configuration
1

I have some awnings on my house, that I am controlling via a shelly 2pm, so one switch is extend, the other is retract.

Full extension or retraction takes 28 seconds, and I currently have automations that will extend half way (14s extend), or the whole way (28s extend), or retract (28s retract). I have these exposed to Alexa so that I can say “extend rear awning” etc.

I’d like I way for HASS to store a value for how many seconds it has currently extended/retracted, to know the position, which I think I can do with HACS extensions (storing a value in a variable), but ideally I’d like to (as I can with my lights) be able to say “set rear awning to 30%” and have it translate that to 28x0.3s runtime, assuming it’s currently fully retracted, or say, 28x0.1s runtime if it’s variable currently tells it that it’s at 20%.

Is this something that is possible?

If you converted your Shelly to ESPHome you could use this:

Having just spent the last 30 mins trying to figure out how to flash the shelly with ESPhome and finding very little on google, this might work better, thanks :slight_smile:

You either need to flash with direct wiring

or use this to get to tasmota and then to esphome
