About

NMEAconnect

This utility app acts as a server or bridge for NMEA data, connecting to various sources like TCP/UDP, BLE, and GPS. It organizes data into modules and can forward messages to other devices, acting as a multiplexer or repeater.

Highlights
  • NMEA 0183, NMEA 2000, SignalK, MQTT support
  • TCP/UDP, BLE, internal/external GPS, Logfile connection
  • NMEA multiplexer, hub, and switch
  • Server/repeater for NMEA messages
  • Background updates and logging
  • Message filtering and rules

NMEAconnect can connect to almost any NMEA source using TCP/UDP, BLE, internal/external GPS, Simulation or Logfile and act as an NMEA server/bridge via TCP/UDP. With NMEAconnect you have: ∙ support of NMEA 0183, NMEA 2000, SignalK or MQTT data of almost any device ∙ a simple setup with preconfigured sources plus versatile configuration options ∙ all values ordered into clear 'Modules' ∙ a NMEA multiplexer, hub or switch ∙ a server/repeater to forward NMEA messages to other devices (most NMEA-WiFi gateways are accepting only one client) ∙ a server of the internal GPS Position as NMEA data to an external device ∙ a MQTT broker, client or gateway ∙ ‚unlimited‘ NMEA log (even when NMEAconnect is in background) ∙ nmeaconnect:// protocol to provide NMEA data e.g. to a Filemaker database ∙ background updates ∙ a visual indicator for NMEA activity ∙ Environments to handle different setups ∙ Message-Rules: Block, Gate Time and TalkerID for each NMEA sentence Supported & preconfigured Devices: For a complete list of supported devices please visit: www.zapfware.de/nmearemote/sources/ ∙ WiFi: Actisense W2K-1 AstraYacht B&G: Vulcan, Zeus comar (NMEA-2-WiFi & i300W/i320W) Digital Yacht (TCP, UDP & NavLink 2) GoFree™ (B&G) GMM (NMEA 0183 & N2k) iKommunicate nke NMEA WiFi Interface NMEA over IP (TCP, UDP) Open Skipper (N2k Datagram) Quark-elec PilotTech - AIS Pilot Plug WiFi PredictWind DataHub Sailor Hat WiFi Gateway SailTimer Air Link™ ShipModul: MiniPlex-2Wi, MiniPlex-3Wi(-N2K) SignalK Vesper: Cortex, XB 8000, Watch Mate Vision vYacht Yacht Devices YDWG-02 (N2k) Yakker ∙ Bluetooth: Calypso: ULTRASONIC, CUPS 4.0 & NMEA CONNECT 4.0 OpenWind RaceBox Skywatch BL 500/1000 ∙ Internal: Core Location (iOS GPS) iOS Barometer ∙ Misc: LogFile Simulation String NOT Supported Devices: ∙ Garmin GNT 10 & chartplotters ∙ Raymarine WiFi devices (these companies are not interested in collaborations and still keeping their systems secret - vendor lock)

Features
Read full description

Make sure you have the latest app version. Turn on your Bluetooth. Tap the icon to open the App. It will search for all Epoch batteries within the range of your Bluetooth device and provide a list. If all the batteries are not listed, move closer to the battery location and refresh the screen. Choose the battery you want to look at. The Epoch intelligent battery management system and the active equalizer are connected via Bluetooth to monitor the battery status, collect, store and process information during battery operation in real time, exchange information with external devices, and solve the safety, usability and usage of the lithium battery system The key issue of life is to extend the service life of the battery to a certain extent, and to enhance the stability of the battery pack to a certain extent. 1. Display real-time voltage, current, power, internal resistance and other parameter values, and display them in the form of instrument panels and numbers; 2. Display the real-time voltage and alarm status of all single batteries. If the reported parameters trigger the alarm value or protection value, an alarm will be prompted; 3. Each data comparison of the battery cell, the voltage difference. Maximum voltage cell Minimum voltage cell. And the display of cell balance 4. Cell temperature warning. Real-time alarm for over temperature, short circuit, over voltage, under voltage 5. Record the warnings that occur at each moment. 6. Record all battery protection times. Best Regards !

Verdict

The call

The clearest difference is review sentiment: NMEAconnect at 86% against Epoch Li's 29%. NMEAconnect also leads on rating (4.7 vs 2.6). Epoch Li's advantage is price (Free vs $3.99) and update cadence (every 3 weeks vs every 5 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

NMEAconnect holds the better App Store score, 4.7 against 2.6. That said, the two scores are not equally well evidenced: Epoch Li has 70 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 86% of NMEAconnect's written reviews are positive against 29% of Epoch Li's.

UpkeepUpdate frequency

NMEAconnect ships an update every 5 months, Epoch Li every 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
