Frequently Asked


  • Assigning a device to a location (room and zone) is necessary to start recording data. This can be done in two places:
    1. Please navigate to the devices list in your AROYA mobile app. Find the device that you’d like to assign in the list of available devices. You may click the QR code button to bring up the camera on your smartphone and use it to scan your device's serial label, which will automatically find the corresponding device in the devices list. Click the device and assign it to the desired location.
    2. Navigate to the web app at Find the devices list in the settings tab. Locate and select the device(s) you'd like to assign. Assign the selected devices to the desired locations. 
  • Please navigate to the Facility tab in the settings menu item on the web app at Here you may add a new room with zones, or select an existing room to make changes.  
  • Make sure that the device has not moved a great distance from the gateway. Reset the gateway with the device nearby. 
  • Please see the Gateway Troubleshooting Guide for more information. 
  • As the plant grows, roots are colonizing more of the pore space in the media, effectively leaving less space available for water retention. This is often seen to a greater degree in smaller media sizes.
  • Volumetric Water Content (VWC) is the measurement that AROYA uses to describe water content. VWC percent reflects the volume of water compared to the total media volume, rather than the total saturation, which is relative to the VWC at field capacity rather than media volume. Please read our AROYA- Cultivation Quick Start Guide for more information.
  • Please read our AROYA- Cultivation Quick Start Guide and tune into our weekly Office Hours live every Thursday at 1:20pm PST to submit your questions. Agronomic advice sessions together with one of the AROYA Customer Success Team members will be available to AROYA GO customers. The hourly cost for this is $500 per hour. Please contact AROYA Support at to schedule your first session today.


  • Simple Answer: The TEROS ONE is superior to the T12, period. We optimized the circuitry in the TEROS ONE to leverage a shared set of pins to measure multiple things, and even more precisely and accurately than the T12.
  • Details: The T12 has two separate circuits in the same sensor: one to measure dielectric (RAW), one to measure  EC. Each circuit uses a pair of electrodes (positive potential and ground). The two circuits share the same ground electrodes, this is why T12 has 3 pins (instead of 4). TEROS ONE has just one circuit to measure both dielectric and EC (it’s a complex dielectric sensor!). So just two electrodes, or two pins.
  • The TEROS ONE was designed to work in combination with AROYA noses. Please use the AROYA API to get your data out of the platform  if needed.
  • Yes.

Existing customers who already have TEROS 12 sensors: You may order additional TEROS 12’s (which we’ll still carry lower inventory of), or the new TEROS ONE. There is also a trade-in promotion to upgrade your TEROS 12 sensors to TEROS ONEs.

When mixing TEROS 12 and TEROS ONE sensors in one facility, we recommend that you separate these sensors between flower rooms, only using one type of substrate sensor per room. The reason for this is to avoid confusion with readings being slightly different between the sensors due to an increased accuracy with the TEROS ONE.

New customers who started with TEROS ONE sensors: You may order additional TEROS ONEs.

  • No, accuracy has nothing to do with sensor density. The sensor density has to do with getting a representative selection of measurements for the population of plants being grown in a zone. The same sensor density recommendations apply for both the TEROS 12 and the TEROS ONE respectively.
  • The Terralink sensor, like many other sensors, measures dielectric. However, it only does a good job in low conductivity environments. The TEROS ONE is the only sensor that measures precisely AND accurately in conductive, high salinity environments. This makes all the difference because high salinity environments is a key characteristic of grow mediums used in cannabis cultivation.

The diagram below shows charts of the scientific testing behind these assertions.

To make this easier to understand,  we have also abstracted the relative characteristics of each sensor using the “targets” below. The tightness of the “shot grouping” indicates how precise each sensor is, i.e. how repeatable its readings are. Tighter grouping means higher precision.

The relationship of the center of the “shot grouping” to the bullseye indicates how accurate the sensor is, i.e. how close the measured value is to the underlying truth (eg. your room is at 76 degrees but the thermostat measures 77 degrees). The closer that group is to being centered on the bullseye, the more precise it is.

  • Calibration costs money and adds complexity to any sensor. With the TEROS ONE measuring dielectric directly, the calibration needed is minimal and less costly.
  • Just like with the TEROS 12, the TEROS ONE doesn’t come with a living soil calibration. Considering this, using the generic soilless calibration would be appropriate to use for relative measurements and relative crop steering. PLease note, a lot of times “soil” isn’t actually mineral soil, but a mix of soilless media.
  • No, the TEROS ONE will not be available to be used with the SOLUS. The SOLUS will continue to be available with the TEROS 12.
  • The TEROS ONE doesn’t have any specific substrate volumes it dictates. However, the volume of influence for the TEROS ONE is about 1 liter of volume.
  • Yes, the TEROS ONE will read close to 100% in water. However, the TEROS ONE was designed to be used in soilless growth mediums.
  • You don’t. Substrate specific calibrations will be offered for the TEROS ONE only. The TEROS 12 has been offered with a generic soilless calibration since its introduction to AROYA, and no other calibration will be offered at this time.
  • The TEROS ONE will be offered with a generic soilless calibration as default. Customers who have access to Harvest Groups may use these to select between rockwool and coco calibration as well.


  • The AROYA CLIMATE ONE provides alerts for whatever ranges the customer has set up in the AROYA UI. The CLIMATE ONE is a “headless device”, meaning it doesn’t decide and add alerts on its own. 
  • You should never need to calibrate the CLIMATE ONE. The CO2 sensor leverages dual beam NDIR technology to automatically compensate for sensor drift over time.  Its other sensors are designed to withstand condensation events that would typically incapacitate other climate stations.  Its new aspirated design ensures it is consistently accurate under harsh conditions. The Pulse Pro is not aspirated which makes it susceptible to harsh environmental conditions such as extreme heat from HPS lights which could cause inaccurate readings. If a customer gets different readings between different climate stations, you should trust that the CLIMATE ONE is most likely the source of truth.
  • Prior to applying any pesticides that may leave residue on the sensor module inside of the CLIMATE ONE, it’s recommended to cover the station with a plastic bag (such as a ziploc bag), or to remove the station from the area which is to be treated. If the station has been contaminated and readings have been affected, the station would have to be returned to Addium for service. This is not covered by warranty.
  • Not available for sale. However, there will be an option to have the H421 CLIMATE ONE be brought back to Addium for warranty repair or replacement. If the device is outside of the warranty period, or the warranty has been voided, the device can be returned for repair for a service fee.


  • AROYA SOLUS allows a user to take spot WC/Temp/ECpw measurements, independently of the “always on” TEROS ONE sensors included with AROYA GO. Users can use either the dedicated SOLUS mobile app, or the SOLUS section in the AROYA mobile app to take measurements. There is no limit to the number of SOLUS units, however customers typically use one at a time.
  • In many cases the SOLUS (which uses a TEROS 12) will have similar readings to the new TEROS ONE sensors included with AROYA GO. But in certain cases, such as high salinity environments or low water content conditions, the TEROS ONE will outperform the TEROS 12 with regards to accuracy.
  • AROYA GO will only be offered in the US and Canada to begin with. AROYA GO will be offered in more countries in the future, however the timeline for this has not been established yet.
