Why is this discussion on this forum?
Because this is where we are connected! Kiwis for Kiwis!!

Ah, that is a difference - I am using Ecotricity via SolarCity, and have a fixed price contract with them so no variability in pricing month-to-month.
Thanks for the heads up. Some of my bills had a positive charge for exporting and some the correct negative one. I’ll register my concern with ecotricity

I’m looking to buy a H3X system, are you able to connect them to home assistant nowadays? My current inverter is connected to a modbus by wifi, and i’m able to use this saj-modbus inverter plugin… however i doubt that plugin will work on the H3X
Does anyone else have a Goodwe Solar Inverter that’s missing some data in the Home Assistant integration? We have no grid import, export, or total power usage. They are present in the SEMS API integration but unfortunately the API is deprecated in May (maintainer is working on a solution).
We also can’t figure out what the ??? sensors refer to. They originally said Grid L1 or something similar, but are definitely not the missing sensors.
Nothing a bit of pressure on them to release the API documentation wouldn’t fix.
Guessing and reverse engineering to extract valid data is obviously a pain.
This is why I recommend avoiding GoodWe inverters - their hardware is robust, but their software interface is very poorly documented.
Try the HACS goodwe integration as it is often a bit more up to date and my goodwe shows a lot more sensors using it than your picture shows.

Indeed 
I use it to set the battery on eco charge when the cost of electricity is low and the battery needs a top up.
Now, to convert W to kWh and kWh to W… integration sensors, yeah?
Can’t make graphs with two different units!
Testers please!
Hi all,
I was previously using a pretty messy scraping solution to pull my power data into HA from Powershop — it worked, but was never going to be a permanent solution. Last week Powershop rolled out their new site which promptly killed it, I’m about to get my first EV so wanted to automate the charging based on off peak power etc etc so I took the opportunity to build something that should be a bit more robust and thought I’d share it.
The new integration talks directly to the Powershop GraphQL API (the same one their new website uses), so it should be more reliable than scraping. It installs through HACS and sets up via a standard config flow — just your email and the one-time code they email you.
So far it has:
- Account balance and voucher balance (the packs you have bought)
- Current electricity rates (peak, off-peak, shoulder)
- Usage and cost for the current billing period
- Estimated total cost and how much you still need to buy in packs
- Billing period pack coverage percentage
- A view of upcoming billing periods — shows what you’ve already bought in Future Packs vs what’s still to cover, for each month ahead (same data they show in the month by month bought vs expected box)
The power pack forecasting was the tricky bit and might still not be the best way to do it but it mirrors how the Powershop site works out what portion of your redeemable pack pool is committed to each upcoming period.

Would be great to know if it works for others (or doesnt) — if you run into bugs or issues feel free to raise it as an issue in the repo.

Smart Door Locks in NZ
I am about to build a new house and would like feedback about smart door locks available in NZ.
Brands, models, pros and cons?
Thanks,
Rob
It’s not really a conversion, but an integration template/helper will calculate the energy used by integrating the power over a period of time.
To go the other way, you could just calculate the average power (energy kWh / time h).
Some of your entities are somewhat confused.
Power is an instantaneous measure, W or kW. Energy is power across a time-period, Wh or kWh.
Eg PV generating at a power of 7kW for 3 hours produces 7x3 = 21kWh of energy.
You have :
Lifetime Solar Power 79.00 kWh (should be Energy)
Todays Solar Power 3.50kWh (should be Energy)
Great that you have the integration working!

Hi! Great work on this
Anyone else in the NZ community installed this?
Anyone have any issues with equipment from the storm this weekend? My UPS shutdown script was thoroughly tested and I lost a shelly 1PM (burnt out).
