Our PW2 was installed almost two months ago at our vacation home near Parry Sound, ON, Canada. We've had two major power failures since installation, the first lasting over 3 hours back in late August. Once power was restored to the grid, I noticed in the mobile app that there was no flow showing between grid, PW2, and house. Also, the SoC of the PW2 kept dropping by about 2-3% per day. After several weeks, I finally made it back to my vacation home, reset the energy gateway and the PW2, rebooted, and discovered all returned to normal.
Well, this past weekend I happened to be at my vacation home during a wind storm, which knocked out power for almost 25 hours. Thankfully, our water supply, fridge, internet access, automation servers, and lighting all kept power during this time (thanks to PW2!). When power was restored, the SoC of PW2 was 51%, but again I noticed no flow showing in the mobile app.
I spoke to Tier1 support at Tesla, they told me Tier2 will call me back within 1-3 business days. Meanwhile my SoC has dropped to 45%.
It's frustrating to have to manually reboot my PW2 system after a power failure. Clearly it wasn't designed to operate this way, especially at a vacation home that isn't always occupied.
My PW2 is running v 1.24.0 firmware, and since late August has suffered from certificate errors when I try to connect locally via a browser. Hope this gets fixed soon.
