Sugarbush monitoring hardware for any size producer
I only need to watch the pump house.
Start with a Sensor Hub.
Plug the sensors in, turn it on, and you have the status of your pump house on your phone in under 30 minutes. Vacuum, tank level and temperature, over its own cellular link.
Sensor HubI want nodes on my mainlines, now or down the road.
Start with a Gateway.
A gateway lets Sap Spy scale to a producer of any size. Lose vacuum at the end of one mainline and the app shows you exactly which one, so you fix the leak, save the walk, and keep every tap pulling.

How it works
Up and running the day it arrives
- 1
Place a hub or gateway at the pump house
Vacuum, tank level and temperature from day one. It arrives with the SIM activated. Turn it on.
- 2
Add nodes where you want eyes
End of each mainline, each releaser, the sugarhouse tank. Three sensors per node, any mix.
- 3
Watch it on your phone
Live readings, a timeline you drag through the season, and a text or push alert the moment a line drops.

Live in the app
Vacuum on every line. Tank levels. Alerts you choose.
Every reading from your hubs and nodes, by site, on your phone or any browser. Drag the timeline back through the season. Set an alert on a line, a tank or a temperature and get a push or a text the moment it trips.

What producers say
Once you have it, you wonder how you sugared without it.
It is so simple to set up and use. Overall a great addition to our operation.
Dr. Tim Perkins, UVM Proctor Maple Research Center
As soon as there is an issue you know it. I would have lost a day's production without it.
Ed Z.
This thing is fantastic. It saved me countless trips back and forth from the woods.
Justin K.
Knowing the tank level is great. It lets me plan my day around how the sap is running.
Keith W.
Being able to plot the data is awesome. It gives me peace of mind knowing my pump is working properly.

Sap Spy paid for itself several times over.
