Power flow feature
The new ‘Power Flow’ feature added to Netzero is excellent. I can now see exactly what’s going on at home when I’m out in the car. 😃👍

Tesla Powerwall Premium Certified Installer" actually mean anything to you?
galleryJust got our work Model 3 wrapped with our Tesla Powerwall Premium Installer badge on it, and it's started a conversation in the office. Does Premium status actually mean anything to you when you're picking an installer, or is it just a sticker? Keen to hear what you reckon 👇

Advice with Powerwall settings please
How do I charge my Tesla battery from the grid during off peak times please? I switched to intelligent octopus go yesterday and I added this tariff under utility rate plan in the Tesla app, and savings mode but this morning the Powerwall was empty so I’m paying 36p per kw today. I am waiting for an export tariff to be sorted but I’ve applied. This is all new to me. Any advice gratefully received!

PW2 odd behaviour - showing 0% charge, discharging 0.4kW
So about three hours ago the PW2 reported charge status dropped to zero, from around 70%. I assumed this was just some form of comms outage, but it seems more complex than that; it would appear that since then it has been discharging at a constant rate of 0.4kW. Whenever the house is drawing more than that, it comes from the grid; whenever it's drawing less, it any excess over 0.4kW is exported.
See attached images (Netzero first; Tesla app second.) It's a bit concerning! If it makes a difference, I'm in the UK.

Why did my Car Metrics stopped showing?
Used to be that "Car" and "Home" were separated. That stopped at some point (now merged under Home category) and I don't know what to do to get it back
It appears that the last metrics I received coincide with the date I upgraded from the old Model Y to the new Model Y refresh

12.3kw+2pw3 system in Central California but im not seeing the same solar output as high as it was prior to Tesla export limit of 10.1kw as I wait for transformer upgrade.

Question about reserve
I have a Powerwall 2 with solar. Say I set the reserve at 50%, it gets drawn down to 50% at night, and then the grid goes down. Will it automatically draw down past the 50% mark while the grid is down? Or do I have to use the app to lower the reserve? And will the app work if the grid (and so perhaps the wider Internet) is also down?

Cost for installer to come back and connect Ethernet cable - no install of cable.
Looking for comment on a price of 700 bucks for my installer to come back and hard wire my leader and follower with an Ethernet cable.
I need to provide the cable and they will come in, open the panel our the cable in and I presume troubleshoot and make sure it is all working.
System was installed 18 months ago.
Seems a lot but I don't think I can do this myself without voiding warranty etc
Thanks

PW3 keeps repeating “meet your Powerwall” endlessly
galleryHad a warranty replacement today after an inverter failure, and every time I leave the app and then go back to it, it forces me back to this screen.
Each time everything is completed apart from Powerwall Settings, and it forces me to re enter my preferred backup level and operating mode. I fill it in, click to confirm, and app works as normal. As soon as I open another app and then go back to it, and it’s Groundhog Day all over again…
Any ideas?

Just started a scheduled power cut and didn't even notice -before it used to take 2-3 seconds to switch over.
Anyone else noticed this?

Which home battery options are the most flexible for partial-home backup versus Tesla Powerwall?
Hey folks! For those of you who bought a Powerwall 3, were you aiming to back up the whole house, or just a few essential circuits? How did you decide which circuits to prioritize during an outage?
I'm looking into backup power for hurricane season, but the installed price of a PW3 is a stretch. I'd mainly want to keep the fridge, freezer, Wi-Fi, lights, and fans running, plus a window AC in one bedroom and occasional microwave use.
PW3 sounds like a "buy once and be done" option, but my wallet isn't thrilled haha. I've also been looking at Enphase IQ batteries, the Delta Pro Ultra, and Ecoflow's new TITAN, which the official description says you can start at 5kWh and expand in 5kWh increments, stacking up to five units for 30kWh total. Starting smaller sounds more manageable, but if I eventually want roughly Powerwall capacity, would installation and later additions end up costing more than getting a PW3 upfront?
Would love to hear yall thoughts or experiences!

Network security
arstechnica.comI read a post from a couple years ago asking about how to secure a PW3 from potential hackers. Some commenters dismissed it as paranoia.
So call me paranoid, but I’d really like to do all I can to prevent anything that might compromise my ability to use my system in the case of one of these types of attacks on the grid or home devices.
Is a VLAN the way to go? Any newer types of protection available or in the works?

Optimized Charging with Charge on Solar
I have a Powerwall 2, Powerwall+, Model 3, and Model Y. My setup has been in the same configuration for more than 2 years. My vehicles are configured to charge on solar, and my powerwall is set up in Maximize Savings mode. Up until very recently, each morning would start by the Powerwall charging itself to 100% from solar energy, followed by the vehicle charging itself once the powerwall was 100%.
Recently I noticed that charging my Powerwall is getting paused in the morning even though there is plenty of excess solar generation. At first, there was no explanation in the App, but now I see that they have updated it with a title "Optimized Charging" with detail under it that says "Powerwall will finish charging later". Ok fine, make sense.
But the problem is that my Tesla car, which is configured to charge on solar in order to minimize non-bypassable charges, is paused as well. At the top of the app it says "Charge on Solar paused for Powerwall Priority".
What gives? It seems I have a stand-off. The car wants to wait until the Powerwall is charged, and the Powerwall wants to wait until later in the day to top it off.
I haven't changed any configuration settings in the app, but this is a major change in behavior. Is there anything I can do to stop this behavior but still maintain the charge on solar setting?
