I would not worry about child logs really.

scottgu3 · May 23, 2020, 1:13pm

I've been recalled from home automation projects this morning by SWMBO to attend to some home organization projects...so I'll have a look at this sometime this PM. Have a couple of the new Jasco Zigbee outlets to install too, so lots of fun to be had for sure!

I snuck some time in to confirm it works nicely again now.

Couple of observations, and I expect this is a limitation of how Tesla presents the data.

The Nominal System Energy (kWh): data is the capacity of 1 battery. I'm not sure why, but 2 batteries should be 27 kWh.

Nominal System energy also appears to be some sort of Static Value, and would appear to be the Max that my inverter can handle. (10kWh), even though my nominal system power is somwhere around 18 * 315 Watts (5.7kW).

Interestingly, the app also gives forward and reverse power (from grid, from panels, to grid and to load/house. Seems like that data ought to be hiding someplace in the stuff you're able to see. Not sure if it is, but it seems like it should be.

Working great. I have a nice dashboard set up showing the attributes from the Powerwall system. Very cool.

snell · May 23, 2020, 4:27pm

I will take a look at what I can find... The numbers are what the device sends back, but maybe I can find ways to tweak that.

snell · May 26, 2020, 11:06pm

Either of you running into any issues lately?

If possible... could either/both of you set your Parent device to Debug logging, and capture a refresh for me? I want to see if there is still anything missing and see if I can narrow down some way to identify things like the combined battery capacity and such. If you want to PM them to me (to help make sure Serial #s do not get into public view) that is fine.

scottgu3 · May 27, 2020, 12:10am

Mine has been running smoothly, no issues at all.

I'll run a refresh!

Scott

jared.zimmerman · May 27, 2020, 12:16am

@snell any luck being able to pull the current house draw or current incoming flow from solar?

snell · May 27, 2020, 12:49pm

I think those are possible. I will check tonight.

jared.zimmerman · May 27, 2020, 7:36pm

everything seems to be working smoothly for me for the last few days running 0.2.4 and 0.1.3

Version 0.2.5 is now posted for the TeslaDriver. Minor changes trying to narrow down that frustrating Device data (the initial logging I added before does not appear in the latest data from Jared for some reason).

Still working on the best way to determine system totals. At this point it looks like it will be counting the number of Powerwalls and then just multiplying the nominal values since I am not finding an overall total. Or even separate % levels per battery for some reason...

scottgu3 · May 28, 2020, 12:42am

15 mind to bedtime! Seems like a great time to load a new driver! Woo! Here we go!

S.

scottgu3 · May 28, 2020, 12:49am

Loaded perfectly. Just sent you a data dump in a PM.

Noted that it thinks I'm not getting grid power, even though its dark out. Tesla really makes this data strange. Lol

S.

jared.zimmerman · May 28, 2020, 12:55am

Will load it in a sec, but just wanted to say that even with the Tesla software I can’t access charge levels of individual batteries, I assume the gateway obfuscates this, so I wouldn’t bother spending too much time searching for that. Who knows how Tesla chooses to optimize charging. I don’t have a use for it anyway. Grid in/out and solar in/out I would want to visualize on a dashboard.

scottgu3 · May 28, 2020, 12:58am

Good point.

S.

jared.zimmerman · May 28, 2020, 4:43am

The link at the top of the thread still says 0.2.4 did you update the url, or not change the version number in the code?

snell · May 28, 2020, 3:35pm

Just double checked, version 0.2.5 is posted. If you use the link, your browser might bring up the cached version. Instead, I recommend going into the Driver Code window for it and select Import. That will always bring in the latest published version.

snell · May 28, 2020, 11:53pm

Version 0.3.0 is now posted!

Reworked the way aggregate data is handled so it will add a lot of attributes and events (we can remove the events if you find no use for most of them). But with Instant Power being displayed by Site, Battery, Solar, or Load now you can track the power usage at that moment by area.

I also added 3 status attributes that are booleans:
Grid Being Used
Powerwall(s) Charging
Solar Generating Power

Hopefully these changes help make it all more useful.

jared.zimmerman · May 29, 2020, 12:06am

Somthing might be wrong,

I'm in debug and the long logs generated are

current system state is :

the main driver shows this

Solar is being generated, but because we're in "high time of use" power billing rate, the solar that is being generated is going to the grid and I'm using my cheap stored power.

So solar should be a string maybe? (Not Generating/Sending to Grid/Sending to Powerwall)

scottgu3 · May 29, 2020, 12:59am

Certainly works and is recovering more items as said. But like @jared.zimmerman I'm still seeing the grid Being used as false, even though in my house, I only pull from the battery when the Grid is down.

There's something odd in how Tesla is dumping that data, as it also reports my battery as charging, which it it doesn't do off the grid (its night here) unless we're under storm watch, which we presently are not.

But no errors!

Thanks @snell!
