As the power grid has grown more unstable here, I have quite a few UPS's here and needed to determine when to replace the batteries.  The linked URL has a YouTube video detailing the process.  In short, these are the steps:

Remove the battery from the UPS
Connect the battery tester and make the following selections:

Out Of Vehicle
AGM Flat Plate
CA (Set to lowest possible - 100)

Record the Internal Resistance

In version 6.9.2, Unraid added a lockout for 3 login attempts (per IP address).  I often fail this and am locked out from the Web UI while I impatiently wait for the timeout to expire.  Here is a quote from the release notes:

For webGUI login you now get 3 login attempts per IP address before a 15-minute cool off is enforced. Further, the timestamp of the last three failed login attempts per IP address are stored in files located in /var/log/pwfail/<ip-address>. Note this only applies to webGUI login, not ssh or telnet.

So, it appears that if you remove the file corresponding to your IP address on the Unraid server in the /var/log/pwfail directory, you don't have to wait for the timeout.  

I've been looking for a reliable way to get outdoor temperature into Home Assistant for automation purposes.  I've been using openweather which gets the weather at San Martin airport, but the reported temperatures versus what the temperature actually is here can sometimes be off by more than 5 degrees.  This is a solution that I can mount outside and doesn't require any electricity to run.  I did end up moving to a remote mounted solar panel which was twice the size (and output wattage) as the original.  This allowed me to put the sensor in the gazebo in an always shaded, yet open to air location which is unlikely to be impacted by sun impacting the actual temperature readings.
