App to help with tracking home charging costs?

teslafi or teslamate should do that - teslafi can certainly track charging and how much put in. Don't know if it can separate DC vs AC or off peak vs on peak

That would be fine (TeslaFi) if you use the raw data ... bit of a faff to set up for anyone non technical I expect.
TeslaFi is what you want. Let me know if you need a referral code. It can track home charges (peak and off peak rates), superchargers and automatically download the correct pricing for them, you can add pricing manually for other charges on the go too. Loads of filters to filter by date, location etc.

TeslaFi cannot track variable time tariffs such as Octopus IO. It can handle tariffs that have a set peak and off peak, but not ones where times vary. It also does not handle tariff rate changes partially well.

Me neither, but that is because mine is a lease car and the lease company is the 'owner'.
I can see that data for our own car...

I'm on IO, I just set my default home charge rate to 7.5p - it will be very rare if ever that I charge outside of the IO generated window. If I ever did charge on the expensive rate I would just manually edit the cost of that charge.
Is your app up to date, the latest version? This component appeared quite a few months ago.

Getting a meter directly inline with your charge point feed will give most accurate energy results as it would measure energy used by the circuit (ie as billed) rather than various measurements such as supplied to the battery or measured via uncalibrated method such as CT clamp style which are notoriously inaccurate.
Costing on dual rate tariffs a bit more tricky though. I think my meter has multiple registers but needs to be configured. Probably not an option for flexible rates though as per my earlier comment with IO and TeslaFi.
These meters are pretty inexpensive (I think last one I bought was under £20) and would be quite quick for a competent sparky to fit. Whether they would be prepared to ‘dabble’ with the dark arts that is EV charging is another matter.

I had already seen this. However it lacks a little, especially in the way I can get the data out.
I'll try TeslaFi for starters.
Thanks everyone.
