So You Want to Build Your Own Solar Inverter Monitoring? Here Are the Problems You'll Hit

Every week someone tells me they’re about to wire an ESP32 to their inverter and build their own monitoring. A few registers, a Telegram bot, a dashboard. A weekend project. I thought the same thing. I started Svitgrid because the apps that came with my own inverter were painful, and I wrote about how it started earlier this year. Since...

How I Built Monitoring for My Home Solar System — And Why You Might Need It Too

Svitgrid dashboard: real-time power flow from PV to battery, home, and grid A few months into living with my home solar installation, I realized the apps shipped by inverter manufacturers were, to put it politely, unloved. Menus that read like Modbus register dumps. Graphs that took ten seconds to load. No clean way to share access with my family without...

Advancing Fall Detection: Crafting a Custom PCB for the Raspberry Pi Zero 2W

Schematics of the PCB module In my previous post, Developing a Fall Detection Device with Raspberry Pi, I delved into the initial steps of building a fall detection system using the Raspberry Pi Zero 2W. Today, I’m excited to share the next phase of this journey: designing and fabricating a custom PCB that integrates essential sensors to create a compact,...

Further experiments, writing a Serverless Telegram Chat Bot

In my last article I wrote about how I wrote Telegram Chat for tracking co-working spends. I wrote a chatbot using Java, hosted it on my Raspberry PI 3. Yes, it’s serving its needs, we fully rely on it. However, since this chatbot was written as an experiment, I wanted to proceed with research and investigate how real chatbots are...
