Open Source Day! Time to share some of my private repos I've been working on. 5 repo drops today:

rivflux — Rivian vehicle data logger → InfluxDB → Grafana. Battery, charging, range, all of it. Think early Teslamate for Rivian vehicles. Waiting for the R2!!!
github.com/bttnns/rivflux

hover-dns — Go CLI + DDNS daemon for Hover's (undocumented) API. session persistence, 2fa, Docker-ready.
github.com/bttnns/hover-dns

server-health-monitor — Pure Go / Bash Fedora server health monitor. SMART, temps, Docker, systemd, SSH, backups — with Pushover notifications. Zero dependencies.
github.com/bttnns/server-health-monitor

riv-TOU-guesstimate — iOS app to estimate optimal Rivian charge windows against time-of-use electricity rates.
github.com/bttnns/riv-TOU-guesstimate

probe-inverter.sh — Bash script to probe the Tesla Solar Inverter / Powerwall local API and see what data's available.

All MIT. Go, Swift, and bash. #EV #telemetry, #energy, #DNS, and #ops

Recently I installed Solar on my house and since I've wanted to track my energy consumption a bit more in depth. Additionally, I wanted to make sure that my EV was mostly being driven for Free, powered by the sun.

A few Claude and ChatGPT sessions later, I found out about https://evcc.io - an automatic energy controller to connect your EV Charging with your Solar Infrastructure. This project was made to work with quite a bit of different EVs, Charging Equipment, and Solar Inverters and Batteries.

Funny enough, more than 1 year before the EVCC project started, I worked on my own version of this. Although I stopped at only roughly supporting my own equipment back then. https://github.com/bttnns/ev-solar-divert

Anyway, today EVCC is able to log all data into InfluxDB -- making it easy to wire up grafana and build some fancy visualizations to help become a better producer and consumer of energy.

This chart allows me to visually see various usage, which in part will allow me to shift that usage under Solar Generation -- providing more clean energy to my actual usage, generating more clean energy to the grid, and consuming less and less non-renewable energy overall.

S2000 is about to get a little bit of Ti Breathing after waiting what felt like 50 weeks from https://originfabrication.com/

They do make super high quality parts though, well worth the wait.

Please remember if you need more time you can pause the recording at anytime.

Now, I want you to imagine following that up with a request.

What are you hearing from what I said? I just want to check we are on the same page.
