Watchlog Connect
Sensor Monitoring & Logging
Free · In‑App Purchases
Watchlog Connect is a monitoring and reporting app for Hydrotechnik sensors.
Add pressure, temperature and flow sensors and watch live data on a chart with dual Y-axes, a crosshair and event markers, or as live tiles if you prefer numbers at a glance. Build calculated channels from your readings, including differential, up to 24 in total. Set alarms per channel and get a system notification when a reading breaches its limits.
Record sessions to disk at intervals from 5 ms up to 10 s, depending on the sensor type. Recordings keep writing through the whole session and survive an app restart, so a dropped connection does not cost you the data. Reopen, compare and export past sessions whenever you need to, or export CSV data with full precision and millisecond timestamps. Generate multi-page PDF reports with charts, channel summaries, alarm breaches and event markers.
Watchlog Connect is free to use, with the full sensor set, live charting, recording, alarms, CSV export and PDF reports included at no cost. Connect Plus is an optional annual licence that adds CAN bus acquisition using a Watchlog CAN to Bluetooth bridge.
Available in English, German, French, Italian, Spanish and Japanese.

INTRODUCING CONNECT PLUS
Connect Plus is now available in the app. As well as increasing the number of connected sensors to 24, it brings CAN bus to Watchlog Connect. Connect up to 4 Watchlog CAN to Bluetooth bridges, each supporting up to 24 channels of CAN data. Standard J1939 messages are decoded out of the box, with no files to load, and you can add your own DBC files for any other CAN bus.
- Every signal on the bus is listed live, searchable by name, PGN, SPN or source. Switch a signal on and it becomes a channel you can chart, record, alarm on and report, just like any other sensor.
- Up to four bridges at once. Machines with several controllers are kept apart: two engines sending the same reading are two channels, never one mixed line.
- Machine faults: active and historic J1939 faults with their warning lamps and a plain description, and an optional marker on the chart the moment a fault appears.
- Readings the machine reports as unavailable, invalid or out of range are shown as such and never recorded as data.
Connect Plus also includes the advanced auger calculations (torque from your machine's certificate, and auger speed).
Buy Connect Plus in the app for 1 year or 5 years. One purchase covers your iPhone, iPad and Mac. The CAN tab shows everything it includes.
CALCULATIONS
- New Force (kN) calculation from a pressure sensor and a jack area.
- A calculation can now use another calculation as its source.
- Every calculation shows its result unit and how it is worked out.
RECORDING AND SESSIONS
- Auto or Manual recording is now chosen per session, with a default for new sessions.
- Closing a new session asks you to name it, or to discard it along with its recordings.
- Optionally save where a recording was made; it appears in the PDF report.
REPORTS AND CHARTS
- PDF reports are made from a single dialog: choose the part of the chart to include, add your logo, and the file is named with the date.
- An Events button in the chart sidebar opens markers and triggers, and event markers now show on the navigation bar under the chart.
- Cancel now really cancels in the channel editor, auger calibrations and the events manager: nothing is changed until you press Apply.
CONNECT TAB
- Sensors keep their places in the lists. A sensor that drops out fades where it is instead of making the others jump.
- On iPhone, the CAN tab is tighter: its heading and bridge controls scroll away, and the filters stay at the top.
- The Help manual has numbered steps on every page and opens on the page for the tab you are on.
OTHER IMPROVEMENTS
- Lower battery use while a tab is hidden.
- Many smaller fixes.
