So in a typical home you will have several hundred power consuming devices, but for me at least I am not really interested in each device but rather groups of devices. So at least in Norway these days everyone has a smart energy meter which you can integrate into Openhab either through the Han port on the meter or through an API from your electricity company. This means we have the posibility to get the total power of the home.
So I have been reading this tutorial:
but It looks a bit overkill to create 100+ rules and 100+ Number items.
What I really would like to display is just a simple table like this
|Lights||Down lights, Wall lamps|
|Heating/HVAC||Heating in each room, Ventilation|
|Cooking Appliances||Oven top, Oven, Fridge|
|Washing Appliances||Washer,Dishwasher,Dryer, Robot Cleaner|
|Shower/Water||Hot water boiler, Hair dryer|
|Media||TV,Amplifier, Internet, Smart Speakers|
|Miscellaneous||Tool chargers etc…|
So whats the best approach to do this in Openhab? Is it posible to create a one dictionary that contains powers consumption for each device? Or is some kind of group triggers the path to take?
And how can we best display it in the basic UI?
