My 1st gen HomeSeer HomeTroller Pi was built on a Raspberry Pi 3 B with 1gb of RAM. While this was fine back when I bought it and was just starting my home security and automation re-design and foray into using HS4, recently I’d been having issues with performance and out-of-memory conditions. In 2021 when I bought the HomeTroller, the HS4 software was only permitted to run 5 plug-ins but that limitation was removed in later releases and I upgraded the microSD card to allow for unlimited plug-ins. Unfortunately, 1gb of RAM is not “unlimited” so now that I’m running more plug-ins (10 at last count) I suspected that the cause of the crashes was due to lack of free RAM. Thus, I decided to try and upgrade the Raspberry Pi in the HomeTroller to a beefier model.
