Read electricity meters over Bluetooth or USB with REDZ optical probes.
ZRobo reads electricity meters through REDZ optical probes. It is the companion app for the probes we build and sell at https://probeformeters.com — designed for them specifically, not a general purpose terminal. If you have a REDZ optical probe, this is the app that drives it. WHAT IT DOES • Reads meters over IEC 62056-21 mode C and shows every line as it arrives • Saves each reading as a plain .txt file you can share or export • Connects three ways: Bluetooth SPP, Bluetooth Low Energy, and USB (OTG) • Reconnects by itself to the probe you used last WORKING ON THE PROBE ITSELF • Device settings: read the probe's full status and write settings back • Module configuration: 38 Bluetooth module parameters, compared against our standard values so you can see what differs • Meter line control: baud rate, framing, break, and the power-on default • Diagnostics: every row is what the device itself reported, with a note under each value saying what it means • Battery level • Firmware update over the air, with a battery check and a recovery path for a probe left in its bootloader WHO IT IS FOR Field technicians and meter operators working with REDZ optical probes. It is a tool, not a consumer app: it says what the device reported and does not guess on your behalf. REQUIREMENTS • Android 9 or newer • A REDZ optical probe (KMK118 or KMK119) • Bluetooth, or a USB OTG cable for the wired probe • On Android 9-11, Android requires location permission for Bluetooth scanning; ZRobo does not collect or transmit location LANGUAGES English, Turkish, Italian. UPGRADING FROM ZRobo 2.x This installs over the old version as an update. Readings you saved before are still there.
