Calculate with power measurement/readings
I've searched the forum about Homeys planned capabilities on power readings and measurements, but can't really find an answer.
Homey is able to show/log power readings from wall plugs (if the plug supports this). Also there seem to be some positive buzz on the subject of power reading from of smart home electricity meters (Dutch).
But I would like to know if Homey is able to calculate with energy readings. An example is probably most illustrative.
I have a espresso machine. Turned-on in the morning on schedule (preferably in sync with my caldav agenda).
Turned off ...
- manually (using z-wave app) OR ... this is where my question comes in ...
- if not used for 45 minutes. The problem here is how to define "not used", this is where the power calculations come in.
An (my) espresso machine keeps its pressure and heat on a ready-to-use level. And generates a certain energy consumption pattern.
Actually using the machine for making and espresso gives a different pattern (with a spike) and creates a different consumption average over time.
Is Homey able to (act) turn off an device if (trigger) not "spike" or "average power consumption" has been (sensor) detected in a certain (time) period?
PS In the same way I would like to trigger Homey to send me a message when my washing machine is finished.

Yes, we're working on creating flow 'cards' that allow you to do something with this information.
Fibaro has a wall plug which is both a switch and an energy sensor. It looks like the perfect device for you. A friend of mine used one for his (not so efficient) cooker. My guess is he made a profit on the investment within a month :-)
The features of Fibaro hardware is amazing from what I read online. I don't have one myself yet.
