Cheers!
One last question for 2nite, is there a way to display the rates etc on the energy dashboard or is that where things dont work that great, because it doesn’t allow for this complexity?
What specifically do you refer to?
Yep, looking into it
You could create another cost sensor which combines the daily amount and the monthly demand amount so that in theory it would increase incrementally each day your demand usage went higher.
I chose to make my own energy dashboard. Still got work to do on water and gas.
yeah nice!
i think im going to just understand everything I have setup now that im thinking about it lol!
Sorry again, do you have the AGL max solar feed in amount in NSW.
My first 14kwh is at 10c then everthing thereafter is 5c lol…
I went with the flat 5c. My daily charge is a little less and my general usage is also a little less than yours. not much but when i checked the plans available to me the extra daily charge removed most of the benefit from the first 14kwh exported at a better rate.

Worked it out. Automated upload every night. I’ve excluded a few of my packages with more sensitive information.
You’ll see many differences between my OP and the same files on github. In this thread i tried to consolidate it into a single package for simplicity of the post, and save for a few typos, should work just as well.
SgtBatten,
For when you get around to adding a gas meter, thought I’d post my /packages/gas-meter.yaml and /esphome/gas-meter.yaml files up, if they’re of interest.
Based it upon your code above and also some from bits from this good thread https://community.home-assistant.io/t/using-home-assistant-to-calculate-my-energy-bill-using-data-from-my-solar-inverter/344913/1.
Next to go back and add TOU plus Demand tariff rates to my electricity, using Solar Analytics for the import/export/production sensors (toss up between Huawei inverters or IoTaWatt also) and then add add water meter with 0-800L (average) per day tarrif tier and 801L-??? tariff tiers.
See: https://github.com/Roving-Ronin/Home-Assistant
BTW would you know why every screenshot of Energy Dash has kWh Import cost is a positive $ (like we are paid to use kWh), whilst Export is a negative (like we are paying to export)?
I suppose it conforms with how it is labelled and typical pricing conventions. The dashboard shows cost, so importing increased the number and exporting decreases the number.
Your energy bill is a positive number. Prices in shops or online are positive numbers.
@cloudbr34k Hey mate, I’m in same boat as you. Did you manage to get it to work? If so can you please share your yaml code?
Think of it like a simple math problem.
If daily exported kwh < 10
daily exported * 14c,
else
10*14c + (daily exported -10) * 5c
Should be fairly easy to convert to that where required.
For monthly cost sensors you might benefit from saving the daily one to a monthly utility meter or something so the value just accumulated automatically without requiring more math.
Thanks. 
Mainly interested in what @cloudbr34k did with the code to only use general usage and demand. My bill only shows General Usage and Demand Usage (4-9pm).
Ahh sorry i didn’t check which response you replied to. I thought it was a different post of theirs.
Your code would be much much simpler than mine. You can disregard the different tariffs in the daily, monthly usage etc you wont need the automations to set the usage tariff as it’s constantly the same. You need to update the demand utility meter and automation to fix the times and remove the high/low demand differentiation (just have demand and no-demand)

hey mate, sorry i have the SgtBatterns code added. But I had to redo my HA install a few months ago, then had a baby so this little project has fallen to the side. but what he wrote is what I was going to do.
I might have a crack now actually

Hi SgtBatten,
Thankyou for the amazing comprehensive script, as a total noob this is very complex, but also very challenging and too good to just pass on. So I bit the bullet and have been at this all day trying to figure this all out and get it working. Any assistance would be most appreciated.
My setup.
I have a shelly EM which have one clamp on the Grid & one clamp on the Solar feed.
sensor.shelly_em_channel_1_power (Grid)
sensor.shelly_em_channel_2_power (solar)
Ausgrid is my supplier with the following.
Peak: 15:00 to 21:00
Offpeak: 21:00 to neaxt day 15:00
Peak tariff: $0.40920
Offpeak tariff: $0.20950
Feed-in tariff: $0.10400
Daily rate: $1.21
I have created the “packages” folder and the files in there is “energy_costs.yaml” & energy.yaml
- energy.yaml (is empty as I don’t know what to put in there)
- energy_costs.yaml (has the one I tried to alter for my requirement, below), I’m not sure if its right
- I like to keep the shoulder rate in case for the future if things change.
- Why is the electricity export power daily showing W.

We should start with the import and export sensors.
Your Shelly is giving you power in W but you need energy in kWh. So first you want to make two template sensors, one that gives import and one that gives export in kWh. This is not included in the yaml I’ve provided as it is the first assumption at the top.
You should call them electricty_imported_power_kwh and electricty_exported_power_kwh because that what the package is looking for.
I’m on mobile currently but if you can’t find any examples of how to do it I’ll help of course.
Where you have entered your Shelly entities, change the back to the names of the sensors you make.
Edit: I realise naming them as imported and exported “power” was a bad idea in hindsight. That is just how I colloquially refer to using electricity in the house. Maybe change power to energy for future pricing. I’ll try updating the OP when I have time
Thanks so much for the prompt reply [SgtBatten].
Just for the fullness of my question 4 and your answer and to help others in the future, I have created the 2 sensors & changed them to the below. Settings > Devices & Services > Helpers > Create Helper > Riemann sum integral sensor >
Name: electricty_imported_power_kwh
Input Sensor*: sensor.shelly_em_channel_1_power
Integration method: Left Riemann sum
Precision*: 2 decimals
Metric prefix: k (kilo)
Time unit: Hours

I have also updated the OP to rename power to energy as that is the correct term.
you may want to re-do those helpers now too to avoid a desire to rename them at any later point.
