Which station-battery bank to visit next — and why — from the recordings and calibrations you already have.
How a bank's status is decided
  • Only from recordings you uploaded: the newest one matched to each bank by the Site and Bank names typed on Battery Watch — exactly, or ignoring case, punctuation and words like “substation”. Anything that matches no bank, or two, stays unassigned.
  • Amps are estimates from a unit calibrated on site against a clamp meter. A recording made without a calibration has no amps: the bank shows “No current data” — never a guess.
  • Discharging: below −0.5 A est. at the last reading — the battery was carrying the load, so check the charger and AC supply. Float rise: the newest week's float current at least 50% and 0.2 A above the week before, same calibration only — an early sign worth a visit. Stale: no recording in 30 days.
  • It does not measure electrolyte level, cell voltage or specific gravity, and it can't tell which cell is weak — only which bank to visit, and why.
Fixed-unit monitorsNew

A unit left beside a bank's cable keeps reporting through the gateway; a monitor turns its readings into one estimated-current minute per minute in the cloud, so the cloud's discharging, float-rise and no-readings alerts can work with nobody on site. Derived on the server from the fixed unit's readings with the calibration you fitted on site. Same physics and caveats as the phone estimate; not a protection, metering or compliance instrument. Needs the unit reporting through the gateway.

New: fixed-unit monitoring has not yet run unattended on a substation.
