ZRobo
ZRobo reads electricity meters through REDZ optical probes. It is the companion app for the probes REDZ builds and sells at probeformeters.com, designed for them specifically, not a general purpose terminal.
Reading meters
Reads meters over IEC 62056-21 mode C and shows every line as it arrives. Each reading is saved as a plain .txt file you can share or export.
Three ways to connect
Bluetooth SPP, Bluetooth Low Energy and USB (OTG). It reconnects by itself to the probe you used last.
Device settings
Read the probe's full status and write settings back. Module configuration compares 38 Bluetooth module parameters against the 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.
Firmware updates
Firmware update over the air, with a battery check and a recovery path for a probe left in its bootloader.
A tool for the field
Field technicians and meter operators working with REDZ optical probes. It says what the device reported and does not guess on your behalf.
