rbAmp Wireless

Coming Q3 2026. Plug-and-play AC monitoring with WiFi, BLE, ESP-NOW, and LoRaWAN — open firmware out of the box. Same metering core as the bare I²C modules you already know, in a single PCB with the radio integrated. Cloud-ready on first boot, re-flashable to ESPHome / RBgrid / your own Arduino sketch whenever you want.

Drop your email and we will tell you the day pre-orders open. First batch ships with an early-bird discount.

Already running bare rbAmp modules with your own ESP32? You probably don't need Wireless. The line is built for users who want one PCB, no wiring decisions, and a default-Cloud experience.

Two hardware tiers

The Wireless line mirrors the bare-module tiering you already know. Same metering accuracy, same firmware family — just with the radio integrated.

rbAmp Wireless Basic — $8–15

Single-phase consumption monitoring for one or three current channels. ±2–3% accuracy. Alternative to Sonoff POW R3 with open firmware and owner-controlled cloud.

  • 1 voltage channel + 1 or 3 current channels (UI1 / UI3)
  • BASIC tier metering (consumption only)
  • Cloud-ready on first boot, ESPHome / Arduino flashable
  • WiFi + BLE for setup, optional ESP-NOW for mesh

rbAmp Wireless Standard — $15–25

Bidirectional metering for solar / battery / regenerative loads. ±0.5–1% accuracy. Alternative to Shelly EM Pro at 2–3× less.

  • 1 voltage channel + 1 or 3 current channels (UI1 / UI3)
  • STANDARD tier metering (consumption + export, signed P, sub-10 mA noise floor)
  • Same radio and connectivity options as Basic
  • DIN-rail friendly enclosure option

Choose your firmware

Wireless modules ship Cloud-ready, but the firmware is replaceable in five minutes. Pick what fits your stack.

  • rbAmp Cloud (default). Scan a QR code on the module, register, monitor. Free Plus tier for early users (6 months locked-in pricing).
  • ESPHome. Native Home Assistant integration with our pre-written YAML. Drop one block, get all sensors.
  • RBgrid. Free self-hosted energy monitoring with tariff zones, AI insights, and time-series storage. Runs on your own Raspberry Pi.
  • Custom Arduino / ESP-IDF. Full control via the rbamp-arduino library — same code as the bare modules, just with the local Wi-Fi/MQTT bits added.

Re-flashing is supported and documented. Shipped Cloud-ready, flash anything else when you want.

rbAmp LoRaWAN — long-range, no WiFi

Need remote monitoring without WiFi? rbAmp LoRaWAN ships as Basic UI1 only (M+3 timeline), 10+ km range to your LoRaWAN gateway. Use cases:

  • Farm pumps and irrigation panels
  • Remote cabins / off-grid installations
  • Building submetering where running Ethernet or extending WiFi is expensive

Frequently asked

When will Wireless launch? Q3 2026 estimated. Subscribe above and we will tell you the day pre-orders open.

Can I use bare modules with my own ESP32 instead? Yes — that is what the existing bare Basic and Standard lines are for. Wireless is for users who want one PCB and no wiring decisions.

Will Wireless support Z-Wave or Zigbee? Not on the roadmap. The radio mix is WiFi + BLE + ESP-NOW + LoRaWAN.

Is the Cloud subscription required? No. Wireless ships Cloud-ready as a default, but the firmware works fully standalone (ESPHome / Arduino / RBgrid all integrate without Cloud).

Open hardware? No — the hardware is closed. The firmware is open and re-flashable.

What microcontroller is inside? ESP32 family, similar to the host MCU you would use with the bare modules.

Apply for early access

Want to be among the first to test Wireless before public launch? Drop your email and a short note about how you would use it. Limited slots; selected applicants receive sample units at production cost in exchange for honest feedback.

Early access form coming online closer to the launch window. Until then, the Get notified at launch signup above is the right entry point — we will reach out to early-access candidates from that list as the beta opens.
