Yeah, it looks like that (measure LED flashes) is only half the answer and I won’t get around hooking into my SMA inverter for solar data.
Trouble is I dont have the Webconnect module needed to connect to it and I believe installation has to be done by a licensed installer. Getting a quote now
What do you mean with “something like this”?
Hi Jamie,
Noticed you are using an Eagle-200. I am thinking of purchasing an Eagle, so I was wondering if you could give me a few tips?
I have a stand single phase home, with solar. Do you know if the Eagle-200 is able to identify the solar activity i.e. feed in / feed out etc?
Would appreciate any info you could provide.
Thanks, Mark
Hi Mark,
The Eagle-200 works well, it was a bit difficult to enable through Powercor’s portal, but that was not the fault of the Eagle. After talking to Powercor support, they quickly had it up and running. Home Assistant works well with it, in fact the new Energy Monitoring feature in Home Assistant works out of the box with it.
I provides realtime data for consumption and feed in.
The only bug I have with it is that it occasionally falls off the wifi network and needs to be rebooted.
Definitely worth getting one for the price…
Cheers,
Jamie
I was also doing some digging into this. From what I could find if you have a smart meter that does live reporting (Synergy are rolling this out so you get 30min snapshots of energy usage) then the customer can authorize Western Power to grant access to this data, and this can be retried by an API see:
As a third party entity, can I retrieve metering data for a customer? | Western Power
though annoyingly it does cost money, another way would be to pull this data directly from synergy. Looking at their website it appears to make a call to retrieve all the needed data to construct the graphs.
i looked at scraping the qynergy site and even started writing a python script to do it but stopped when i realised that it was up to 2 days behind and that was not very useful for me.
if anyone is interested i would be happy to put what i have on github for someone else to keep working on.
@TomW1605 definitely post onto github, would like to take a stab at it and see where it goes.
In the meant time did you come across any other solutions or tried the LED reading option?
i ended up with an IoTaWatt. found one for $200 on gumtree. not overly helpful i know. sorry.
also i haven’t had had it installed yet but have been testing it on my 3d printer and it seems to work well
i will put the code on github tomorrow. im about to go to bed and i want to make sure it works for what it can do and doesn’t break anything before i upload it. will post a link once its up.
Nice, i didnt even know about these, so you just going to clip it onto the main feed into the home?
unfortunately the version i got has solid CT meters so i need to get a sparky to come in and unscrew the wires from the switch board to put it through the meters. but then i need one to install a power point nere the switch board anyway so thats not an issue.
EDIT: to clarify a bit, my 3d printer has an external switch mode power supply with only screw terminals. so you have to screw the 240v wires in yourself. so i just unscrewed the wire to put the meter on.
hmm I shall have to look into getting something like this setup… much better than the Synergy option, that site is a complete dumpster fire
that’s one way to look at it. on the other hand at least the data is loaded in raw instead of rendering a graph server side and just sending that to the client. its pretty easy to get the data out if you want. just a bit to delayed to be much use. and that is not a synergy thing. from the reading i have done it looks like it is the fault of western power
Actually i was referring to the amount of data piped in from the login redirect. URL redirect contains allot of the PII data right in the URL.
Would have thought it would be more sensible to return a uid for the session and then have web parts on the page load in the relevant data as required. In fact if I recall allot of that data doesnt even appear on the screen so why even send it.
eh thankfully I’m not a web dev so guessing there’s a reason that Im unaware of
no i dont think that is good practice but like i said it makes it easy to scrape and use as an API
Sorry I’m coming into a long and extensive thread and asking a newbie option.
I’ve just ordered solar so will end up with a smart meter and inverter. I’m obviously keen to make use of the energy facilities of HA.
Is the gist that I’ll get my solar info from my inverter over wifi? Will my inverter give me everything I need or will I also need to look into a CT clamp?
Is the general consensus that iotawatt is the way to go?
Yep, or Ethernet if your solar inverter has the capability and you run a cable to it.
Should do. What inverter are you getting?
Only if you have an inverter that can’t interface with HA by itself.
Definitely.
Ahh I see. I’m getting a Goodwe - it’s an 8.5kw/single phase but I don’t know the model number. I have my fingers crossed the inverter will have wifi although I suppose a cable could be an option too.
So, sorry to be dense… but by “everything I need”, will it also demonstrate power that I am consuming in the house? Or just the amount of power generated and exported by the panels?
Supplementary question… if I do need an Iotawatt, would an electrician look at me funny getting help installing it?
No, the solar system will only tell you what it is generating.
For consumption you need an iotawatt or similar. You should be fine if you have a decent sparky. If you’re in Perth I can do it
Geez, Such a perfect custom component. Anything similar to work with AGL?
