Frigate performance optimization using Gemini
Impressive Frigate performance optimization using Gemini. My Raspberry Pi 5 + Coral TPU setup handling 8 cameras has seen a 38% drop in CPU usage, despite increasing the detection frame rate from 4 to 5. Gemini made several smart suggestions, including generating a shell script to ffprobe camera streams and determine their characteristics, splitting and…
Home Assistant on RPI 5 hardware
Upgraded my Home Assistant to RPI 5 hardware recently mainly, so it better handles cameras in Frigate + Google Coral TPU. I am now monitoring 5 security cams at 10 FPS with ~25%-ish CPU load, the RPI 4 wasn't able to handle half of that without overheating, and 75%-ish CPU load

Physical vs Virtual
The $35 Raspberry Pi isn’t really $35 – comparing the true cost of physical Pis against virtual machines for home automation duty.
Speech generation with Node-RED
Speech generation with Node-RED: the house reads notifications aloud so I stop picking up my phone 50+ times a day.
Exposing Raspberry Pi’s network setting files to /boot so that they are visible on a PC
Exposing the Raspberry Pi’s network settings to /boot so they can be edited from a PC – handy when cloning SD cards for other networks.
Monitoring my home automation system uptime
Free uptime monitoring for my home automation system with UptimeRobot – a notification when the house goes dark, whatever the reason.
Duck DNS updater in Node-RED
Dyn and No-IP got too commercial, so I moved my dynamic DNS to DuckDNS with a small Node-RED updater flow.
Improving my home automation system’s Data Quality
Improving my home automation system’s data quality – filtering the garbage readings that quietly break downstream logic.

Live streaming the house martin nest to USTREAM.TV from a Raspberry Pi – motion-triggered stills were not enough.
House martin cam
House martins are nesting in my unfinished tool shack, so the kids and I put up a nest camera instead of peeking in.
Presence detection using phone’s WiFi and Node-RED
Detecting who’s home by pinging the phones’ static DHCP leases from Node-RED – 15 minutes of work and pretty reliable presence detection.
Voice controlling things with a smartphone and Raspberry Pi
Voice controlling the TV and heat pump with a smartphone and a Raspberry Pi – I’m no voice control fan, but this one earns its keep.
