Paul's Programming Notes

Paul’s Programming Notes is an independent technical publication focused on practical programming, home automation, and self-hosted computing. Its articles share hands-on research, product comparisons, configuration guidance, and troubleshooting insights drawn from the author’s own projects. Readers will find detailed evaluations of compact computers for homelab servers, including HP Desktop Mini PCs and comparable Dell and Lenovo models, with attention to performance, memory, storage, power requirements, and compatibility.

The site also covers integrating Victron solar equipment with Home Assistant, explaining how to use Venus OS and Modbus/TCP to bring battery and system data onto a local network. Posts discuss related hardware such as Raspberry Pi boards, USB hubs, monitoring devices, and power adapters, alongside software configuration and common setup issues. Rather than presenting a general catalog or commercial service, Paul’s Programming Notes offers independently written technical guidance for people building and maintaining home labs, renewable-energy monitoring systems, and other practical computing projects
