Timebased Calculation

[barkimde]

Is there a possebility to implement a timer or a trigger for a device? For example: I have one powermeter and i just want to seperate depending on the time the waterheating (2 hours from 4 till 6) from the rest.

This is not yet possible.

You can use daily fixed energy, that allows you to define an "on time", but it will increase constantly during the day. Not only from 4 to 6.

A) I might consider adding a service to set virtual power sensor to a given value. Than you can do this with an automation at given times. Set to X watt at 4 o' clock. Set to 0 Watt at 6.

B) Or maybe I can extend the playbook functionality with an option to specify specific times.

Anyways a development is needed for this.

A seem to be a nice feature to have anyway and allows for many use cases, so I would probably implement that. Not sure when.

Thanks for the fast reply. Its not so easy to discover the consumption of the heating from scratch ;-) In summer times i have only the standby-usage of about 8 watt (thats already configured). At lunch time every day the heating prepares the hot water. Once a week on sunday is the legionella-programm. This takes a little bit more. Every mode has fixed times like cron jobs, so these programs dont have a fixed usages of power.
And in the colder seasons, between the summer-programs is the floor heating running. that's the reason i try to split the consumption and optimize the heating pump.
A playbook cant show me the differences, when it's getting colder or hotter again.
