My OctoChargeCalc - Octopus Agile pricing tool

Zarch

Not sure why, but my original and rather lengthy "My Octopus Agile & Go tariff analysis/comparison website" thread has been removed?

Don't this understand as it was the place we all talked about Agile / Go etc?  Very strange.

Ah well...... onwards and upwards......
---------------------------------------------------------------------------------------------------------------------------------------------------------

At the start of lockdown they said use the time to learn a new skill. So I took that onboard and here’s the result.

OctoChargeCalc - https://octochargecalc.energy-stats.uk/

I knew a little bit of python as that is the backbone of my https://energy-stats.uk website API calls, but i’d never written a webapp before, so this has been massive learning curve doing this in Flask framework.

What does it do?
Well you tell it how much you want to charge your (EV / Battery / Heat Pump) in kWh each and every day, tell it the charge rate of your device and where in the country you are.

It then goes away, pulls out the cheapest number of required slots per day for the timeframe selected from the underlying energy-stats.uk database and displays graphs and a short summary of what that amount of energy historically would have cost you on Agile.

You can also select an ‘alternative’ unit price to compare against… ie 14p/unit to compare against the same time frame.

So i’m hoping that potential Agile (or even Go) customers can use this to visualise (in pounds and pence) their charging requirements.

I’ve not yet fully announced this to the world or linked to it from my main energy-stats website, so think of this as a sneak peak or a live beta test. Very much a slow / phased release. 

Please send over comments or if you spot any bugs etc.

Like I said, this has been a massive learning curve and undertaking, so I do expect some bumps in the road.
I'm praying its all going to hang together when more than one person starts to use it!!
If it falls over....... it will need more work!! 😁

Any comments or feedback would be greatly appreciated.

Cheers, Mick

Superb tool again Mick thanks very much. Looking to move over to Octopus once they can install me a SMETS2 Meter.
I just started playing about with Node-Red to bring SolarEdge info into it, but I want to connect up to SolarEdge modbus once I get it installed.
I have recently bought a SolarEdge 3kWh inverter, 9 x 340kWh panels (3000 kWh), Lux AC controller, and 14.4kWh Pylontech batteries. Got another 6.5 Kwh panels going in at end of June along with another SolarEdge inverter.

I've been tweaking the app all week based on feedback.

I've primarily adding some form validation to ensure only valid selections are accepted as well as lots of minor little tweaks and changes.

Thanks everyone for the feedback and testing.

If anyone has any further comments or bug reports, please let me know.

Cheers 14.4 was available yesterday as a battery size, but not working now. Could we have a 4 month option please. Trying to work out my potential winter bills

Have fixed the 14.4 problem..... sorry about that.

Will consider the date range thing.......  find something that works for everyone..... maybe free-form months, maybe weeks.

Zarch,

Have you tied in an applicaiton to anything automated to bring in your power when its at the lowest level if you are on Octopus Agile?

I know someone has written something already? not tried that yet as I cannot get onto the agile tariff till they fit my SMETS2 .

Great stuff Mick. 👍

There are Octopus IFTTT applets that work with certain smart plugs/switches when the Agile price drops below a set amount.

Thanks EVandPV, sorry I mean into the Pylontech batteries to bring it in automatically I think someone wrote some code to do it.

Yes, Octolux by Chris Elsworth, which talks to Agile and the Lux controller.
