Computer Replaced

Computer was replaced because Cruise control, auto steer and FSD did not work. Would not offer gray steering wheel.

• 2-3 hours was forecast duration
• 6 hours actual time
• FSD did not show up when car returned to driver
• Was told after Autopilot calibration, all would be fine
• Still no Autopilot
• Service manager failed to close service ticket
• After service ticket closed, FSD showed up and required more calibration
• All local profile settings were lost; seats, mirrors, steering wheel, garage door opener, WiFi etc
• All cloud driver profiles lost, 24 hours later still lost. Profiles showed up at about 26 hours. No action taken, they just showed up.
• Cruises control, auto pilot and FSD work now.
• Received V12.3 FSD next morning.

LiftMaster Chamberlain Garage Door Opener WiFi Connection

Revised: Tue Feb 27 18:30:30 EST 2024
Original: February 27, 2024

Could not get Liftmaster garage door opener to join WiFi on a UniFi network. Had to install a separate router. Used the Gl-Inet Mango Yellow router.

Got some tips from the Chamberlain Group

Symptoms were failure to join SSID. Stuck in the single beep mode. Never got to double beep.

• One beep: connecting to router
• Two beeps: connecting to internet
• Three long beeps: successfully connected

Had to add router hanging off local network. Using a Gl-Inet in access point mode did not work. Had to be in router mode. Can't explain it. Those Gl-Inet routers are less than $30.

Called tech support, very nice and willing to help but could not solve my problem. Tech support did suggest a web browser method to configure instead of the app. Basic steps are as follows.

• All button pushes are at the opener, use a ladder.
• Press and hold the black button (between the arrow buttons) until 3 beeps.
• Press and release the large yellow learn button 3 times. Will be some beeps and then the black button will flash blue.
• Connect phone or computer to SSID something like MyQ-111. This is the last digits of the serial number.
• Direct browser to http://setup.myqdevice.com
• Tap "Start" and follow procedure.
• When the page says "Did you hear three long Beeps", wait until you do, don't answer the question until you hear the 3 long beeps.
• If lucky, all is well now.

UniFi Additions and Modifications

Revised:7 Feb 07:13:25 EST 2024
Original:Feb 4 06:51:14 EST 2024

A few things added to and modified on UniFi systems. This page will expand with details over time.

on_boot system

• on_boot system that provides persistent modifications and additions with every boot despite UniFi updates that erase so many things. This system is based on a github project but greatly simplified.
• Add legitimate LetsEncrypt certificates via on_boot to controller and manually to cameras to make local access more pleasant.
• Install ssh keys via on_boot for convenient login
• tailor dnsmasq via on_boot for local name servers and reserved addresses etc

Ookla Speedtest on Gateway

• Refer to ookla page
• Use script on referenced page
• armhf for raspberry 32 bit
• aarch64 for unifi, unvr, cloudkey, etc and raspberry pi 64 bit

SNMP Install and Configure

• Add snmpd to gateway for MRTG to access. Avoid turning SNMP on for the whole network, just the gateway.
• works on UniFi UGX and UDM, probably any gateway
• Reference
• must run apt-get update prior to install
• apt-get install snmp snmpd libsnmp-dev
• configuration must be in two locations
• /usr/share/snmp/snmpd.conf
/etc/snmp/snmpd.conf
• Need systemd unit file to start snmpd (comes with snmpd install)
• /lib/systemd/system/snmpd.service
• Some unifi updates remove the snmpd binary. If this happens must stop and start the snmpd.service after reinstalling snmpd. This could be incorporated into on_boot
• Install commands

  apt-get update
  apt-get -y install snmp snmpd libsnmp-dev
  cp snmpd.conf-src /usr/share/snmp/snmpd.conf
  cp snmpd.conf-src /etc/snmp/snmpd.conf

The NEC and NM-B Romex Cable Gauge for 48 Amp EVSE Circuits

Mon 22 Jan 16:10:00 EST 2024

If using NM-B (Romex) cable, the 2020 National Electrical Code (NEC) requires minimum 4 gauge conductors for a 48 Amp EVSE. A 48 Amp EVSE such as the Tesla Wall Connector is a continuous load and therefore the circuit conductors and devices must be rated for 125% of the 48 Amp continuous load. NM-B 6 gauge cannot be used because NM cable ampacity is only 55 Amps at 60C and the 60C column must be used.

Ryan Jackson has published Electric vehicle circuit sizing (NM Cable) YouTube video explaining the code requirements that make NM-B 6 gauge non-complient.

New Jersey has published a 2020 Construction Code Communicator Volume 35, Number 3 stating that NM-B 6 gauge is ok. This is contrary to the NEC.

Soneone in a Rivian forum summarized the issue like this: In a nutshell, it’s the “continuous load” rule 215.2(A)(1) that trumps the “next size up” rule 240.4(B). The maximum ampacity of #6 Romex is 55amps. Since an EVSE is “continuous load”, rule says you must multiply 48A load by 125%=60amps, too much for 55ampacity #6 Romex.
