Harvestree provides four measurement ports with industrial M8 connectors. Each port is assigned a measurement mode in software and paired with a compatible probe. All active ports are acquired in one pass and sent in a single LoRaWAN uplink.
Modes are set in Toolbox only (not downlink). Changing a port’s mode clears that port’s calibration and alarms. Use catalog probes, or third-party / custom only with MOIZ approval. Payload combinations that exceed 51 B are blocked at commission time.
