This next generation sensor node provides 3 generic ports allowing you to connect 1, 2 or 3 sensors externally to the device. As of Oct 2025 the list of compatible sensors include
Vacuum Sensors
Tank Level Sensors
Pulse Counting Modules (Water meters)
Pressure Sensors (coming soon!)
This style of sensor node can communicate to either existing sensor hubs or to the new Sap Spy Gateway V2.
Common configurations include:
1 Port Vacuum Sensor: Monitor the end of 1 mainline or a releaser.
2 Port Vacuum Sensor: Monitor the end of 2 mainlines
3 Port Vacuum Sensor: Monitor the end of 3 mainlines
1 Vacuum + 1 tank level: Monitor vacuum and tank level at a releaser location.
1 Vacuum + 1 Tank + 1 Pulse counter: Monitor vacuum, tank level and sap flow at a pump house.
Minimal configuration needed, the sensor node simply recognizes what sensor type is plugged in. All you do is give each port a name in the Sap Spy web app for ultimate flexibility.
Solar panel provides continuous operation from season to season.
