I get that it seems to save you a few minutes a month but I would be careful thinking it saves you money or helps you deal with money better - it doesn’t and won’t in that order.
you use electricity, a meter records it and you get charged for each unit used and recorded. How you get there (self-reads, remote reads or a person wandering in once per year) makes no difference to the end game. You need to pay for what you use and is recorded on the meter.
to deal better with money I would actually go and read the meter more often. Work out your usage patterns and see if you can reduce usage without reducing comfort and convenience. Either save an amount monthly or go even pay (and with that read meter even more to have data through the year and avoid leaving lots of money with provider). Here once you have their account details and have a direct debit in place, you can set up a payment on each payday (fortnightly here) and watch the account credit increase. My bill is quarterly so if I make sure there is enough covered the amount DD is zero - or very small. I control the payment amounts unlike even pay type schemes.
I have a dumb digital meter and don’t want smart since it doesn’t help me at all. Some still charge more per day for a smart meter - you know the ones that were going to save us money as they don’t need to be read by a meter reader.......
And yes I keep a spreadsheet or two for electricity consumption and solar production and exports. Fill them in from my readings at least once a week from the meter and once a month for my solar (it gives me a report once a month I can copy and paste into Excel
)That’s where I learn about how I am spending money and if I can be bothered to do it better
