Previously, the light-meter was creating a new HTTP request to send every new reading. This now
uses a persistant session to reduce the amount of requests made to the server -- and reduce low
on the system.
The extra exceptions listed and expanded on are mostly for testing. At the time of writing, the
system as a whole is hanging at various parts throughout the day and the intention is to monitor
the Light Meter to see if any of the new exceptions are the cause (or contributing) to the
hanging. The current trains-of-thought at the minute are too many requests (system load too
high) and requests not timing out properly.
I have given the 'mid-point' server a domain name to reduce the need to manually update the IP address if/when the
server needs to be restarted (for whatever reason). The changes here include the new URL.
The URL used here is a domain name and not just an IP address. This
should reduce the need to update the IP address in the code if the
server, currently hosted on AWS at time of writing, needs to be
restarted. The servers on AWS do not keep the same IP address if you
stop and start them.
The abbether.net domain is a personal one and used as a way to reduce
project costs. I did not use this domain when I first wrote the code
here because I did not own it. Long story short, the Covid-19 malarkey
meant the project was put on hold and I ended up owning abbether.net
during the first lock-down. The decision to use the domain is one of
convince my end. I did not want to keep updating the code manually if
the server on AWS was stopping and starting.
