UNI 1-Wire sensor upgrade for Perseus platform.

During 2025 HW group will upgrade all UNI 1-Wire sensors in production. With this article we want to explain the change taking place and the motivation behind it.

In addition to improving the hardware, it was necessary for the new sensors to align properly with the change in the new philosophy established for the Perseus platform, i.e., each external data source serves as a single "Meter," with one or more "variables" available.

In the past, most HW group monitoring devices, whether it was Poseidon2, Damocles2, Ares 12, or any other, operated under licenses focused on the number of "Meter", so all sensors supported this line of reasoning. Each device had a maximum number of "Sensory Values," independent of the number of connected sensors.

With the introduction of the Perseus platform, "Sensory Values" and licenses for the respective monitoring units no longer exist because Perseus units work only with the "Meter", representing a connected data source, or a sensor, detector, other device connected via XML, SNMP, MQTT or Modbus/RTU, and its "Variables," similar to the previous "Sensor Values."

With all Perseus units supporting up to 100 Meters and 1000 Variables, a way had to be found to capitalize on these features. With the first generation of sensors attached to a Perseus unit, one would have a separate "Meter" for each "Sensor Value," thus going to saturate the maximum acquisition capacity of the device sooner in the case of combined sensors.

This will change with the next generation of UNI 1-Wire sensors, updated specifically to accommodate the change in the Perseus platform. With the new generation of 1-Wire sensors combined, they will be represented in the Perseus GUI as a single "Meter" with multiple Variables, thus going to optimize the acquisition capabilities of Perseus systems.

Nothing changes for older HW group devices used with newer sensors-they are backward compatible with everything produced in the 20-year history of the house.
