If any of your AcuRite sensors are offline on your My AcuRite® Dashboard and/or you received a System Alert, we recommend reviewing the appropriate steps below. If all of your sensors are offline, please refer to the top portion of this article titled All Sensors Offline. If only one or some of your sensors are offline, please skip to the second half titled One or Some Sensors Offline.

All Sensors Offline:

If all sensors on the My AcuRite® Dashboard show offline or you received a Communication Loss Alert, you will need to check the AcuRite Access® Connection by following the suggestions below. 

1. What color is the light on the front of the Access model 09155M? Click Here to review what the light on the front of the Access represents. 
2. Confirm the Access is at least 3 feet (.9 meters) from other electronics, including the router. A sensor will send the data packets on a 433 MHz radiofrequency. Other electronics, including a TV, computer, radio, or microwave, can cause wireless interference.
3. Verify that there is a My AcuRite® compatible sensor powered on within 330 feet (100 meters) minus obstruction of AcuRite Access®. 
   NOTE: You may need to bring an AcuRite sensor within 3 feet of the Access for them to re-pair.

If it is still not online: 

1. Remove the backup batteries from the Access (if applicable). 
2. Unplug the unit from the Ethernet cable and the power adapter. 
3. Wait 20 seconds.
4. Power the unit back up by plugging the AC adapter and Ethernet cable back in. (switching to a different Ethernet port on the router may be helpful) 
5. Reinsert the backup batteries (if applicable).
6. Press and hold the reset button for 20 seconds.
7. Wait up to 10 minutes for the sensor information to come back online. If the sensor does not come back online, bring the sensor next to the Access to pair and check the sensor's batteries. 

One or Some Sensors Offline:

If one or more of your sensors is offline on your My AcuRite® Dashboard and/or you received a Loss of Signal alert, please review the suggestions below.

You would want to ensure the following first:

1. Verify that all sensors are within their wireless range of the Access. Under optimal conditions, the units can be located up to 330 feet (100 meters) from each other. Wireless interference and certain construction materials can reduce the wireless signal strength.
   NOTE: The Wireless Rain Gauge Collector model #06034M has a wireless range of 100 feet (30 meters).                                                                                                              
2. Confirm the sensor is at least 3 feet (.9 meters) from other electronic devices. A sensor will send the data packets on a 433 MHz radiofrequency. Other electronics including a TV, computer, radio, or microwave can cause wireless interference. 
3. Ensure that you are using recommended batteries:

• Verify you are using fresh batteries in the sensor. Lithium batteries are recommended for installation locations where temperatures can go below -4°F/-20°C.
• Verify you are using batteries with a nominal voltage of 1.5 volts.          
  NOTE: Some rechargeable batteries carry low or inconsistent voltages that may not properly power the device.  
• Mixing different battery types (brands, old/new, etc.) is not recommended.

NOTE: It may take approximately 10 minutes for the sensor and Access to synchronize after batteries are replaced. 

If one or more sensors are still offline:

1. Bring the offline sensor(s) within 3 feet of the Access. Allow at least 10 minutes for the units to pair.
2. Your sensor may have disconnected from the Access but regained connection as a new sensor. Check the list of Available Sensors on the Devices page of My AcuRite®. If a sensor of the same model is listed, remove the currently offline sensor and add the Available Sensor. 
3. If the sensor(s) is still offline or not showing as an Available Sensor, remove the batteries from the sensor and change to a new ABC channel. (If you are using a display unit with said sensor, make sure to change the display unit's ABC channel to match. A hard reset may need to be performed with the display.)
   NOTE: If all sensors are set to the same ABC channel when using the Access, this can create too much traffic on a single channel. We recommend spreading your sensors out over the three ABC channels to prevent this. For example, if you have 6 total sensors, set two sensors to each ABC channel. 
4. If the sensor(s) is still offline, please repeat step #2.
