Battery voltage on the telemetry strip
Track battery bank voltage — live from a monitor on the bus, or entered by hand.
With a Wi-Fi gateway added as a bridge, theONE reads house and start bank voltage live off the boat's NMEA 2000 network, wherever your charger or battery monitor puts them on the bus. Without one, the battery tiles on the Mission Control telemetry strip hold readings you enter by hand. House and start banks have their own tiles, so you can track them separately.
Out-of-range readings (very low or implausibly high) usually mean a mis-typed entry or a sender issue at the panel — sanity check before you worry.
Steps
-
Log a reading today
Read the voltage at your panel or battery monitor. With Manual as the telemetry source on Mission Control, tap the bank's tile — House bank or Start bank — to open its page, then tap Update reading, enter it and Save.
-
Watch the trend
Open the tile's history. A house bank that sags a little lower every morning at anchor is telling you something — aging batteries, a growing load, or a charging problem.

Live now — with a bridge installed
A battery monitor or shunt publishing on the NMEA 2000 bus feeds the tiles automatically, decoded from PGN 127508. Nothing to set up beyond connecting the gateway.
This needs a NMEA bridge (a Wi-Fi gateway) physically installed on the boat's NMEA 2000 network. Without one there is nothing to read and entry stays by hand.
