With energy prices skyrocketing all over the place especially in Europe these days many of us try to reduce their energy bill as much as possible and the energy dashboard is one of the greatest tools for that matter.
But why is it so hard to add entities which are not officially supported monitoring devices. In my case I hacked an Aqara door/window sensor to collect data from my dumb gas meter (using the reed sensor, calculating that 100 triggers equal 1 m³ gas). But this sensor does not show in the energy dashboard. I have to write up a template in the configuration yaml, think of adding unit_of_measurement and device_class and most importantly state_class: total_increasing. Who thinks of that?
For my electricity meter there is no way at all to add any readout so I just wanted to have an input_number helper that I fill manually and have the numbers show in the energy dashboard. This is even more complicated as there is no sensor data coming in regularly.
My suggestion and WTH for this WTH month is: Make it easier to use any entity in the energy dashboard, at least any sensor or input_number. Maybe even add a line for some kind of calculation, like x amount of triggers for this sensor equal 1 m³ or 1 kWh.
That would be a huge help for those of us not so familiar with the details of the energy dashboard behind the scenes.
