Count number of espresso cups using power consumption

My Rancilio Silvia has a typical power consumption pattern that looks like this

For a number of minutes the boiler heats up with close to 1.000 Watts, then the machine idles the entire day using between 3 and 180 Watts. Pulling a shot brings the power consumption up, albeit for a short time.

You need ...

• a power measurement device, such as a Shelly Plug S or similar.
• a helper counter.silvia for obvious reasons (add with Settings | Devices & Services | Helpers)
• a helper input_boolean.silvia_running which tells us when we can use the counter (add with Settings | Devices & Services | Helpers)

There are two automations that take care of the rest. One automation which increases the counter by one and another one which sets the helper input_boolean.silvia_running. The helper is true if one of the conditions is met...

• 5min after turning on the machine
• HA started and power consumption is greater than zero (and less than 200W)
• Automations got reloaded and power consumption is greater than zero (and less than 200W)

And here are the two automations
