Administrator rbAmp vs Shelly EM — Modular DIY Metering vs Turnkey Certified These two are not the same kind of product, and the honest comparison starts there. Shelly EM is a finished, certified device you wire in and it works. rbAmp is a metering front-end module — you add c... 12 août 2026 Comparisons
Administrator The rbAmp UI Series — 1 to 7 Metering Channels on a Single I²C Bus for Your SCT-013 If you have ever tried to meter more than one circuit with PZEM-004T boards, you know the pattern: one board per circuit, one UART per board, a nest of wiring, and no shared timebase between them. The... 12 août 2026 Tech Articles
Administrator Log Energy Data on a Raspberry Pi with rbAmp — CSV and SQLite in Python, No Cloud The monitors read it; the relay acts on it — this one keeps it . An rbAmp module and a Raspberry Pi make a standalone logger: timestamped voltage, current, power and kilowatt-hours appended to a CSV f... python 30 juil. 2026 Projects and Tutorials
Administrator Trip a Relay on Over-Current from a Raspberry Pi — Local Load Control in Python The Pi monitor reads the current; this one acts on it . When a circuit stays over your limit, a Raspberry Pi switches a GPIO relay to shed the load — locally, in its own Python loop, no Home Assistant... python 30 juil. 2026 Projects and Tutorials
Administrator Meter Several Circuits from a Raspberry Pi — a Multi-Module rbAmp Bus in Python The single-module monitor read one circuit. A whole home has more — mains plus branches, or three phases. On a Raspberry Pi the answer is the same as on a microcontroller: a bus . Two or three rbAmp m... python 30 juil. 2026 Projects and Tutorials
Administrator Build a Raspberry Pi Energy Monitor with rbAmp — Live Watts in Python, No Cloud If your home server is a Raspberry Pi, you don't need an Arduino or Home Assistant to read your mains — a few lines of Python and an rbAmp module will print 230.4 V · 0.21 A · 48 W · 0.97 PF to the te... python 30 juil. 2026 Projects and Tutorials
Administrator Log Your Energy Data to an SD Card with Arduino — Timestamped CSV, No Cloud The monitors show it, the relay acts on it — this one keeps it . An rbAmp module, an Arduino, and a microSD card make a standalone data logger : timestamped voltage, current, power and kilowatt-hours ...

Administrator Does rbAmp work with the Home Assistant Energy Dashboard? Yes — via ESPHome the module's energy sensor lands in the Energy Dashboard out of the box. See the 15-minute Home Assistant setup .... energy faq home-assistant 30 juil. 2026 FAQ
Administrator Does rbAmp need the cloud or a subscription? No. It's fully local and open — a documented I²C protocol with open ESPHome, Arduino, Python, and ESP-IDF libraries. Nothing phones home; you own your data.... faq integration 30 juil. 2026 FAQ
Administrator How does rbAmp handle energy (Wh), and does it survive a reboot? Energy is integrated over exact wall-clock intervals: the module latches a measurement window atomically and the host integrates true active power over the elapsed time, so there's no on-device counte... energy faq home-assistant 30 juil. 2026 FAQ
Administrator How do I change an rbAmp module's I²C address? On current firmware it's a plain, production-ready operation — no special mode, jumper, or factory tooling . You stage the new address, arm the change, and commit it (a two-phase, magic-armed sequence... faq I2C multi-channel 30 juil. 2026 FAQ
Administrator Can I put several rbAmp modules on one I²C bus? Yes — that's a core feature. Modules share one I²C bus and differ only by address. Add circuits by adding modules on the same two wires, behind one host — no extra microcontroller, no serial-port jugg... faq I2C multi-channel 30 juil. 2026 FAQ
