Calculate electricity savings, standard rate against off peak

Energy
1

Hi
I use Octopus GO and only use grid electricity on the cheap rate to charge the house batteries. I have a helper template set up which gives me annual cost.
{{ states(‘sensor.this_years_grid_energy_in’)|float(0) * 0.085}} (8.5 p per unit)
What’s defeating me is I’d like to do a second calculation as above, but at the normal rate of 29p per kWh, then subtract from the higher rate total my actual lower rate I’m paying. That will give me a monetary value of the amount saved over that which I would have spent at the normal price.
Hope that makes sense

This sounds like a very simple template sensor no?

If you pay 0.085 per unit at the Go rate, and you would have paid 0.29 per unit at the standard rate, then you are simply saving 0.205 per unit.

You can save yourself the need to compute the annual total at the standard rate and subtract the annual total at the lower rate, since the total annual saving to date is just

{{ states(‘sensor.this_years_grid_energy_in’)|float(0) * 0.205}}

Thank you for pointing out what I missed!, I’m attempting a complicated solution for a simple problem since neither rate varies! Many thanks :slight_smile:
