Anyone maximised solar panel savings by scheduling specific appliances based on real-time generation data?

[JDRoberts]

I don’t know of anyone who’s fully automated it. There are some people who get phone notifications based on their tesla powerwall statistics so they can make decisions about what to run. The specific integration is quite old and I’m not sure it works anymore, but you might check out the following thread:

Tesla Powerwall II

Here’s a very basic device handler for the Tesla Powerwall II It will show you charge level and the current power for grid, site, solar and Powerwall. It requires a FQDN for your Powerwall, because SmartThings is a PITA about allowing direct access via IP addresses unless you also write a device handler app - and I lost the will to live trying to decipher the awful documentation on doing this. Someone that knows what they are doing could probably sort this out really quickly. The SmartApp simply sends you a push notification when the charge level goes through configurable upper or lower limits, with the simple purpose of alerting you when the battery is full so that you can turn something on to make use of excess solar. The SmartApp could be easily modified to switch a load on and off f…

Also, someone did one a few years ago for fronius, but again it’s probably out of date now:

Fronius Solar Power Inverter

I wanted to share this Device Type I’ve written to read the realtime, day, month, year values from a Fronius Solar Inverter connected to solar panels. The Device Type polls and reads the values from the inverter directly on the LAN. It is a little rough and ready at the moment but hopefully someone else will find it useful. [image] The code for the DeviceType can be found here Let me know what you think, hopefully you don’t find any bugs.

And there was one for Enphase Envoy, but the author is no longer supporting it:

[UNSUPPORTED] Enphase Envoy (local access)

This is my first attempt at creating and releasing a device type - a power & energy meter for a solar system running Enphase inverters. It connects to the Enphase Envoy on the local LAN and thus is not bound to any rate limits or contingent on setup of a developer account with Enphase. This was inspired by this post (with the linked code unfortunately no longer being available). [image][image] A few notes: Unfortunately it is not possible to set dynamic colors on tiles - the main tile will turn green for production of 2kW or more (you could adjust that depending on system size) The peak percentage is based on maximum theoretical output (number of inverters multiplied with inverter size) Peak power is not reported by the envoy - this is the maximum value the device type encountered d…

So these are just some ideas to look at.

One thing to be aware of is that if you are querying a cloud or website, many companies put rate limits on how many times you are allowed to poll that information per day, and that includes information you need for other parts of your system. So that’s something you need to look into as well if there’s a cloud involved. Typically you’ll be limited to about one query every 15 minutes for this kind of purpose, but it does vary from company to company.
