As of Dec 18th 2023, sensor nodes are in stock for the 2024 season. Most orders ship in 1-3 days. 

A SapSpy Sensor Node communicates to the SapSpy Sensor Hub (Sold Separately) allowing you to measure vacuum at different locations in your sugarbush.

A sensor node can be one of the following configurations: 

1) Single Vacuum Sensor with temperature sensor

2) Dual vacuum sensor with temperature sensor

3) Single Vacuum Sensor with Ultrasonic Tank level sensor and temperature sensor (used for a tank and releaser)

4) Single Ultrasonic tank level sensor and temperature sensor (Typically used where an electric releaser pumps to a remote tank where vacuum monitoring is not needed). 

In order for SapSpy Sensor Nodes to communicated to the SapSpy Sensor Hub, the Sensor Hub must include an add-on radio option for +$100. 

Sap Spy nodes are now capable of Spy Mesh. Spy Mesh allows nodes to repeat a signal in order to significantly increase the distance between end of line vacuum sensors and the sensor hub (Cellular Gateway). Videos and additional instructional content will be updated in Q4 of 2022 discussing this new and exciting functionality. 

A single sensor hub can service many sensor nodes (currently up to 40). The recommended maximum number of hops between a sensor hub and sensor node is 4. The expected distance between two sensors nodes is estimated at ~1500' - 2500' through a typical sugarbush. Line of sight, sensor nodes can reach 3 miles+ between two nodes. It is recommended to use a dedicated Sensor Hub per sugarbush location and use that particular Sensor Hub to service all sensor nodes in the local sugarbush.
