Calibrating the ESM-1 Environment Sensors

Growlink portal: portal2.growlink.com

First: Find the room you want to calibrate and click on the room. 

Temperature, humidity and CO2 can be adjusted. 

Second: When in the room, click on the settings gear in on the left hand side. 

Third: Click on one of the sensors.

Fourth: Click on the 3 dots next to the sensor mode you want to calibrate. From here there will be a slider. 

The slider is in increments of 1 degree for temperature or 1 percent for each percent of humidity. If the levels are too far one way or another it likely means the ESM was sprayed. These are highly sensitive sensors that do not take kindly to any level of spraying. They get sticky and then don't read the room and have to be replaced. 

These sensors are a bit over $500 apiece. 

It's critical to cover them before you spray a room.
