Can several too many sensors increase the possibility of data gaps to Weather Underground?

I have 9 sensors on one Smarthub and have not seen any problems.

Thanks.  Then that is one less item that might cause any problems.

I use this at a second vacation home that has the heat on that we use on weekends on and off.   It is in the Adirondacks so I am concerned about the temperature.  

The one thing you may want to be aware of is that the the 300 foot signal distance they quote is not accurate if you are going through walls and such.    The units still work but it will show you with a yellow versus green color that the signal is weak.  

In my house I have three finished floors including the basement where the smarthub is.   The SMARTHUB antennae flips up on the unit.  I am not sure if it radiates the signal evenly in all directions or not.  As I said I have 9 sensors, 8 temp, one water leak sensor which also has temperature on it.

Also you will find that the temperatures are not all the same for all sensors even if you set them in the same room.    Setting up is critical.  I would do the following:   Power them up and set them up ONE AT A TIME (or you won't know which sensor the Smarthub is talking about when configuring it).  Once you give it a name write the name on the back of the sensor with a pen.   Put the batteries in the next one and the Smarthub will tell you is sees another that is not setup.  Please note that if your neighbor has one you can use that one also, there are no passwords.   After setting them up  put them all in one spot at room temperature for 30 minutes to let them equlibrate so that you will know which shows higher or lower temperatures.   You might want to place them near a thermostat to see how closely they match the thermostat.  Then place them all outside (colder temps hopefully) and let them sit for 30 minutes and do the same.  I have found that at one temp it might be one degree higher but at a lower temp it might be .5 degrees higher. 

Once you do that you can tell the application that a specific sensor unit is .5 degrees high and when it shows you the temp it will subtract 5 degrees.  Based on where you need accuracy set it at the appropriate # of offset degrees.   Then based on the namesyou gave them AND WROTE on the back of hte units and place them around the house.

Freezing (32F) is obviously one of the critical temps.   Check your Thermostats to make sure they are reading as accurately as your Acurites.   You don't want the thermostats 35 degrees to be off either.  My NEST Thermostats probably have mo accurate temperature sensors.   They show up a again at slightly different temperatures than some of the group of Acurite sensors.   Please see the Green and Yellow colors on the website myacurite.com showing the signal strength I mentioned above.

 

Once you get them all done the ALERTS are easy to setup.  I have a number of them.  By default the system sets up ALERTS to let you know when the batteries are weak in any unit.  Here is an example of two of my rules for low temp and a water leaks.

Hello William,

Having multiple sensors will not affect the Weather Underground gaps. We are investigating the gaps in Weather Underground as this has been a known issues. Our customers should be experiencing significantly less gaps then before. We do appreciate your patience while we work on this. Have a good day!
