Multi-point temperature logger with cellular

A temperature survey rarely needs one point. Racks in a store, layers in a tank, rooms along a corridor. Genesis reads 1-Wire probe strings, RS485 probes and PT1000 probes on the same unit, and files each probe against its own location so the points never blur into one line.

How it covers many points

A string of probes on one port

1-Wire probes share one cable, each with its own factory address, so a string runs along a rack or down a tank on a single port.

Mix probe types

Use a 1-Wire string where cost per point matters, an RS485 probe where the run is long, and a PT1000 where a process connection needs one.

Each probe keeps its own place

Location is bound to the probe, not to the controller, so one unit covering two rooms keeps the two rooms apart in every chart and export.

Setting it up

Plan the string

Run the 1-Wire cable past each point and fit a probe at each. Label each probe with its position as it goes in.

Name each probe in the dashboard

Assign each probe to its rack, layer or room. That name follows every reading it takes.

Set limits per point

Different points can have different limits: the top of a stack runs warmer than the bottom.

Worth knowing

1-Wire is for short and medium runs

Over long distances use RS485 probes, which are built for long cables.

Calibration stays with the probe

A traceable probe stays traceable when the controller reads it. The certificate travels with the probe.

Frequently asked questions

How many probes can one controller read?

Several per port on a 1-Wire string or an RS485 bus, across four ports. The practical number depends on the cable runs and the reading interval; tell us the layout and we confirm it.

Can I move a probe later without mixing up the history?

Yes. The location is stamped on each reading when it is taken, so moving a probe does not rewrite what it measured before.

Can the controller sit outside a cold room?

Yes, and it should. Run the probe cables in and keep the controller and its battery outside the cold space.

Tell us what needs reading

The sensors, how many points, where they sit, and whether there is power and coverage. We come back with whether the ports cover it and what the installation looks like.
