    How to enable stormwatch only during off peak?

    We get completely free power between 9PM and 9AM each day - and pay higher (than fixed price) rates between 9AM to 9PM. If Stormwatch is triggered during the daytime, then we're paying for all of the electricity charging the 4 PowerWalls (assuming they were each at 35% charge to get started -...

    Power went out for 11 seconds

    We periodically see very brief outages reported by the gateway - usually 5 minutes. When this happens - I can see that our neighbors still have power. What's likely happening is that the Gateway detects something on the grid connection indicating the grid might be going down - so it...

    Why does my GW keep asking me to connect to my wi-fi?

    With the impending shutdown of the 3G networks, Tesla is forcing everyone to turn on the WiFi on their gateways. Though when they implemented this in the apps, they didn't take into account systems that already had WiFi enabled. Our gateway is hardwired to our network (which actually creates a...

    What is a "normal" drop off for solar production in the Winter?

    We have 15.4KW of solar panels and 4 PowerWalls. Our peak solar power months were June (1711KWh), July (1988 KWh) and August (1854 KWh) last year. Our lowest months were February (876), November (986) and December (673). Evidently we had a lot of sunny days in January, since we had 1027.

    PowerWalls offline

    Well... This morning when I checked the Tesla app - we can now change the PowerWall settings - and have updated settings to support our Free Nights plan. The app just started working - didn't receive any notification from Tesla. Hopefully we won't see this sort of problem again - and lose...

    Well... We're getting close to 3 months since our PowerWalls went offline. While we were able to get the PowerWalls operating again last week after the Gateway motherboard swap - 7 days later, we still can't change any settings (other than reserve percentage). Called Tesla energy support...

    After the new motherboard was installed, the new Gateway showed up in our app pretty quickly - as well as the old Gateway. I called Tesla energy support - and they were able to remove the old Gateway from our account. It's been 5 days since the new motherboard was activated - and we still...

    Powerwall in Texas Storm

    When we purchased our custom home, we committed to the purchase while it was still in frame, with no interior walls. Our builder gave us the option to get sprayed foam insulation in the exterior walls and the underside of the roof - something we hadn't considered - and we are so glad that we...

    Update on our situation. I turned off all 4 of our PowerWalls after they had been sitting for an extended period with the status lights off. When the app last reported their status, the PowerWalls were at 35% charge. And because the electronics won't go online due to the Gateway motherboard's...

    Solar panels and clay tile roofs

    We used Hays Energy Services - that's affiliated with Hays Electrical Services. They had an installation crew with experience in tile roof installation. And so far, other than some broken tiles our roofer found when they recently fixed a leak in another area of the roof, we haven't had any...

    The reset switch isn't that useful - when there's a problem, it's probably better to cut off the solar, PW and grid power for a few minutes to force the motherboard and related electronics to completely reset - and then boot back up first with grid, and then adding the PW and solar panels...

    Using the installer web interface, there is a diagnostic for CAN bus. But that diagnostic didn't detect the CAN bus wasn't terminated - and was giving false readings that the PowerWalls weren't enabled. Those diagnostics are useful in almost all cases. Ours was unusual because the CAN bus...

    This morning 3 of the 4 PowerWalls were still showing rapidly flashing green status lights. The 4th remained dark. Went through the cold start sequence once, waiting for 1 minute while everything was off before restarting. TEG still didn't come back online - the status lights visible from the...

    Can't tell since the TEG appears to be completely offline. Will attempt to do a cold start on it this morning - and call Tesla support.

    PowerWalls offline

    Hmm... Something new tonight... Possibly due either to a brief power outage last night prior to the hurricane or having the TEG set to Storm Watch (even though the PowerWalls were offline). 3 of our 4 PowerWalls are now showing a flashing green vertical bar - flashing on an off slowly. The...

    I mentioned to the tech support rep that someone else reported they were on 21.31.1 - and the answer I got was "that is an older release - 21.20.7 is the newest release". Which doesn't make sense since 31 > 20. However, it's possible there was a problem with the 31.1 release causing them to go...

    Just got off the phone with Tesla PowerWall support. The latest firmware is 21.20.7 - pushed out around August 29 - which is after our PowerWalls went offline. So the updated firmware didn't have any impact on the problem. And according to the phone support rep - the problem we are having is...

    Tried that. Threw the breakers for the 4 PowerWalls and solar panels - and the breaker inside the TEG panel which disconnects the grid power. Waited for 10 minutes - and then powered the TEG and reset the breakers for the solar panels and PowerWalls. The PowerWalls won't turn on - all 4 have...

    Just got back from a trip - and checked our TEG is at 21.20.7. From the TEG web installer interface, tried to do a firmware update - and it says our Gateway is Up-To-Date - so we're still at 21.20.7. I plan to call Tesla tomorrow to check on the status of the replacement board - and also ask...

    Reinstalling the firmware is a problem for both the TEG and Tesla vehicles - the software doesn't appear to allow it. The TEG's installer interface allows the installer to request installation of new firmware for the TEG and the PWs. But there isn't a "reboot" or a "reinstall". We have a 2017...

    Checked - the firmware matches - app and TEG web portal. Replacing the entire gateway is a larger project, requiring reconnecting all of the power cabling. Will be much easier to just replace the motherboard. Since Tesla support was talking to engineering - and that's what engineering...

    We haven't - yet. After 3 hours, was able to talk with Tesla. They believe something happened a week ago to take the PowerWalls offline - but they continued to discharge, and because the TEG wasn't able to communicate, they discharged completely. At this point, Tesla believes all 4 of the PWs...

    Well... When I came home - all 4 PowerWalls were completely dark. Tried turning them off and then on - no change. Tried pressing the reset button on the TEG - no change. Threw the breakers for the PowerWalls, solar panels and the grid power and waited 10 minutes - no change. We're getting...

    Our TEG is outside and accessible. However, we'll be home tomorrow and I'll work on the system then. Usually reset switches require more than a single press and release - may have to hold down for multiple seconds. Our system isn't hung - it's running and operating. So a software reset...

    Switchbot is an interesting idea, though it may not fit inside the panel, and would require extending the recessed reset button out enough so the switchbot could reach it. Plus, the switchbot would need to hold the reset button down for a long enough period to trigger the reset. If a simple...

    We're away from home for a long road trip and discovered our 4 PowerWalls appear to be offline. The Tesla app shows 4x PowerWalls and 0% charge. The Power Flow charts show that no energy has gone into or out of the PowerWalls for the past 6 days. The last time the PowerWalls had any activity...

    Is Net Metering a Must in Texas?

    We live in Texas with 44 350W solar panels and 4 PowerWalls. After evaluating plans based on actual performance of our system for 6 months, we selected a FREE NIGHT plan (free electricity from 9PM to 9AM). After one year on the plan, we only used 22% of our grid electricity during the 9AM to...

    Excessive Battery Drain While Parked - Summon

    We took a trip recently when we left our S and X at home for 7 days unplugged. The 2017 S 100D (MCU2/HW3) lost 26 miles of range. It had Summon enabled - but not Summon Standby. And it had Sentry enabled. The 2018 X 100D (MCU2/HW3) lost 9 miles of range. It had Summon and Sentry disabled...

    Which goes further for $43 - a Tesla or a Gas Car?

    Regular gas prices here are around $2.50/gallon. Assuming 25 MPG - 200 miles would use 8 gallons or $20. Current fixed rate plans in our area are available for $.10/KWh. Assuming 330 W per mile - a 200 mile trip would use 66 KWh or $6.60 (though because we get free electricity overnight - our...

    Excessive Battery Drain While Parked - Summon

    We're going to run a 7 day vampire drain test next week on our 2017 S and 2018 X - and may have Summon enabled on both and Standby enabled only on the S - and then compare the battery drain between the two. I suspect the drain on the S will increase to 10 miles per day and on the X will...

    Excessive Battery Drain While Parked - Summon

    We just came back from a 12 day trip and left our X parked in an airport garage. Our X lost around 10 miles of range per day - and was down to 67 miles of range (slightly more than 20% for our 2018 X 100D) when we got to the car. After comparing settings with our S (which loses 3-4 miles per...

    Excessive Off State Power Drain

    May have found the cause of the excessive battery drain. At some point, Tesla added a "feature" for Summon mode - that allows the sensors/cameras to stay on all of the time while parked, to reduce the amount of time required before Summon can be started. In our S - that feature was turned off...

    Parked my car at the airport…

    I just compared the settings for our S and X and found one major difference. At some point, Tesla added a setting for Summon - to tell the software to keep the cameras and sensors running in order to reduce the startup time when summoning the vehicle. In our S - that feature was disabled - and...

    FSD beta v9 release date: this Saturday?

    The vehicle I owned prior to our 2012 S was a Lexus LS. It was the first production vehicle with "self-parking" - which was pretty impressive at the time. But... To get the vehicle to park - it required moving a parking box around on the console display, placing the box on the rear camera...

    FSD H/W Update - a little underwhelming

    Excessive Off State Power Drain

    Two months ago, we left our 2017 S (MCU2/HW3) parked unplugged for over 2 weeks and lost about 3-4 miles of charge per day.

    Simultaneously Pairing Two Bluetooth Devices

    The RV we purchased last year (based on a 2019 Mercedes Sprinter chassis) supports having two BT phones connected at the same time.

    FSD beta v9 release date: this Saturday?

    The Saturday release was supposed to go to "early access" vehicles. Several years ago, vehicles that had purchased FSD before there were even any FSD features available - we're supposed to be added to the "early access" list. Neither our S or X has yet received the new FSD software...

    Which goes further for $43 - a Tesla or a Gas Car?

    Except for road trips - we charge our S and X at home. Since we're under a Free Nights electricity plan (with solar panels and PowerWalls) and do EV charging only at night - our fuel cost (except for road trips) is $0!

    Considering Tesla Solar w/ Powerwalls in North Texas

    We planned our solar panels & PowerWalls to provide us about 50% of our average annual energy. Through a combination of the solar panels/PowerWalls and energy conservation (LED lights, more efficient pool pump, less EV charging due to COVID, ...), we've reduced our electricity from the grid by...

    Federal Tax Credit may be coming back for Tesla purchases

    Here's the link: EV Tax Credit Tesla customers would lose $2500 of the credit because they aren't using union workers. Since the bill passed on a 14-14 vote in a 50-50 senate, unlikely the bill, at least as written, will go anywhere.

    No more radar means the car cannot see through fog?

    When Tesla introduced AP2 several years ago, the phantom braking was a reasonable action for the AP software to take when it wasn't entirely confident about the objects ahead. Especially with Tesla's movement away from radar, the continuing presence of phantom braking should be a concern - if...

    No more radar means the car cannot see through fog?

    Phantom braking appears to have two major causes: The AP sensors are unsure about an object ahead, so it initiates a reduction in speed until it verifies it is safe. The software is taking a very conservative response to potential hazards - including when vehicles cross at an upcoming...
