This post outlines the wiring steps for connecting 2-wire PT100 probes to the Wattics Octopus. You can connect the 2-wire PT100 temperature probes to the Octopus Gateway or I/O Extension units in any available analog input.
Hardware Connection – Octopus Gateway unit
Hardware Connection – Octopus I/O Extension unit
Note: Non supported PT100 probes will require the development of a new Octopus PT100 software driver. This steps involves you sending us a sample PT100 probe for calibration. You may contact us at firstname.lastname@example.org for any clarification.
