Resetting utility meter with tariffs independently

Configuration
1

I previously used an utility meter to track how much energy an EV charger charge session used, by resetting it at the start of each session. I now wish to track two “last sessions” for two EVs.

I naively created a utility meter with two tariffs, planning on switching between the two depending on the EV being charged. However it seems that you can only reset the meter as a whole, and not the individual sensors tracking tariffs. This is documented.

Are there any workarounds with this setup? If not I have the following ideas using a regular (no tariff) meter:

  1. “copy” the result to an individual sensor at the end of a session. This means they can’t be tracked during use.
  2. Use template sensors for each EV and a “filter” boolean to only update if the relevant one is being charged. This will give live updates but I’d have to think about it a bit more :slight_smile:

I’m leaning towards 2. Is that the best approach? Any other thoughts?

Maybe first split total use using tariffs, and then add a resetting one on each of the splits?

Yes that was my naive approach, except you can’t reset the split meters individually, you can only reset both at the same time.

EDIT: I misunderstood your suggestion. I didn’t realise you could pipe meters. I’ll have a play.
