Curious if you are using the Tesla Powerwall Integration in HA? For the life of me I cannot get the integration to keep the login credentials longer than about 5 minutes. I have had to disable it as it just would not stick. Cheers

So as a followup, the heat pump faults are likely related to a needed firmware update on the heat pump and not GW related. I do find the voltages to be higher than I would expect however. In my case the API is reporting 247.1 V on the battery right now. With fluctuations over the last 8 hours of...

FYI... Just checked my Instant_average_voltages. Battery 248, others average 214. Dennis

Hello Bruce, Gateway 2 on 21.44 223a56cd

After a recent install of a new heat pump, I have gotten a couple of High DC Voltage errors on the heat pump. I am trying to determine if this is in any way related to my solar/PW operation. 7.4kW solar w/ 2PW's, Gateway2 and SolarEdge Inverter. I track the Gateway data via a RPI using the...

I've been seeing strange results the last couple of days with grid usage on 21.35.0. I am running two PW's on Self-Powered with 50% reserve. Storm watch off. This morning (attached), while spotty solar with cloud cover, solar is more than enough to cover home use. While battery is charging, I...

Couple of great ideas here, wjgjr. I think the nominal reporting of 100% is worth checking out further by crunching some of the values just before and after the event. As far as sunrise goes, I am not seeing the same thing there. Also as battery rises to 100%, nothing there either. I have not...

7.4kW System w/ 2 PW's I've been up and running for a couple of months now and have been getting data from the API every 5 minutes. I export this data via Raspberry Pi to InfluxDb/Grafana locally and PVOutput for data analysis. I am running the PW's in Self-Powered with a reserve. I have...

Used rhodesman/teslaPowerDash as mentioned above to get things set up on a Raspberry Pi. Used mihailescu2m/powerwall_monitor as a template dashboard and expanded from there. Also used VirtualWolf/powerwall-to-pvoutput-uploader set up on the same Rpi to export all the Gateway API info to PVOutput...

32.05 kWh from a 7.4 kW system.

Just one CT around one solar lead.

CT is located right in the Gateway on one of the incoming solar legs. My setup uses the gateway panelboard for the incoming solar and the powerwalls. The CT is plugged into CT Port 1. I have been doing some reading today in the Powerwall Installation manuals and I notice that CT port 1 is used...

Thanks charlesj. From the responses here it is sounding more and more like a change is needed in the gateway. I went and opened the gateway today and can see there are 3 different CT ports. My solar CT is in port one. And besides the negative house usage showing, the solar generation shown is...

Interesting. Thanks!

No Neurio in this case. Yes, a CT seems to be the suspect. I have also noticed that the daily solar values seem to be almost exactly half of what I am producing as verified by SolarEdge and my utility.

I've recently had a new solar with 2 Powerwalls installed. (Not Tesla Installer) After PTO I started using the app and monitoring the data. While the system seems to be working correctly there is definitely an issue with the metering. Shortly after the solar day starts the house load will drop...

Thanks again. Got it up and running. Cheers!

cwied, I now have a related/unrelated question about Telegraf. Got things set up but Telegraf throws a certificate error. Along the lines of “Certificate is valid for 192.168.90.1, 192.168.90.2.” While my ip range for the gateway is 10.1.xx.xx. Did you have a similar certificate issue and if...

Thanks!

Data is beautiful! Thanks for sharing. Cheers

LAST FIVE OF THE PW is what did the trick! All looks good now. Cheers!

This is purely preemptive on my part. Trying to make sure all is correct and I have any access I might need going forward. Thinking about advanced data collection through the API and from I read I would need to enter credentials there. Thanks for the link. Reading now. Cheers!

No, you understood and that makes sense. Now I another issue but it is going back to the installer. He lined out the original PW and wrote a separate one in. Neither worked. Off to contact the installer. Thanks very much for your quick reply. Dennis

Just finished a 3rd party install of solar and 2 PW's here in AZ. Do not have PTO yet so only have tested at end of install. My question is; I have installed the Tesla app (IOS), set password, logged in and everything looks fine. I have both wi-fi and wired ethernet to the TEG. Today I tried to...
