Hi All - I’m new! Got my ST hub yesterday and am excited to get in the game. One thing I’ve been wondering about is if there is any plans (options?, limitations?) for integrating monitoring of Solar Panels in ST. I tried to do some searches in these forums, groups and projects, but didn’t find anything.
I’ve got a set of solar panels on my home with Enphase inverters. There is web support and I can currently monitor via the web or an iOS app.
@ppmo Currently, ST requires their cloud to access any IP device. If you have an API endpoint of some kind that’s accessible from the cloud, it wouldn’t be too hard to write a custom device handler to poll it regularly and pull out the value(s) you want.
For my foscam, I wanted to find the alarm state (on or off), so I just created a poll method. Foscam values are line separated, so I just traverse through till I find what I want:
If you have a web interface, you could just as easily grab the HTML and parse it that way (although a proper API would be far nicer to deal with).
From that link: Overview
With the Enlighten System Data API, you can develop client applications to request data from existing Enphase systems for an authorized user, and refine the results of the request using query parameters. Currently, the API supports read-only access to your Enlighten data and alerts, at the system level.
Use of the API is subject to the Enphase Energy API License Agreement.
I did already get some things working. I’m pulling system summary and alerts. I’ve got various generation stats (current, daily total and weekly). I’m planning to get a background color change based on any system faults being reported, but have to read up on the app code a little bit more first. It wasn’t working right, but I only spent a few hours so far.
It will be good to switch to using schedule instead of poll.My plan is to add instant, daily, monthly, year to date, and life-time production. Also look up average energy cost and turn it into $ savings.
I just received by ST (on the Wednesday evening). Once I am more familiar I will have more ideas.
Your key charges the data usage to your account. Free account has certain limits on how often you query and how much data etc. They charge for higher usage. So you want people using this device code to register for their own account and use that, not use yours.
Yea I was thinking schduled might work better also. You can configure like a crontab job and just poll every 30min or something like that.
Sounds like a good plan to add the data. I can’t think of a really good use for this which has delayed my implementing it but your implementation is cool. Thanks for sharing !
I didn’t add it to my source control but I added some debugging and I am trying to add the “Powered By Enphase” logo but I can’t get it to show a logo based on a URL so far. I have tried this for other apps and failed also. Not sure what I am doing wrong.
A dumb question, What would be the best way and logic. I want a power outlet to turn on if my current power production is more then 1kw and if it falls below 1kw have the power outlet turn off? We don’t have true net-metering and want to have my battery charger on only when i am producing power.
