06014RM SmartHub Unreliable

  • Question
  • Updated 12 months ago
I have had my SmartHub and 5in1 installed for several months.  Both work fine, except signal strength on hub is low (1-2 bars).  Generally, it works fine anyway, but lately it's been showing signal loss for up to 6 hours at a time.  I tried moving the hub closer to the station; I tried reorienting the hub is a couple of positions; each time I change something I waited to ensure that the readout was updated.  In all positions, and at all distances, it shows 1-2 bars.  I can understand that full strength might be difficult to achieve; however, I can't believe that no matter what I do I only get 2 bars.  I see others are having connection reliability issues, even from 15' away.  Do you have a fundamental problem with the 5in1 transmitter?  I am using new Eveready Lithium batteries as recommended.

Try changing the channel on 5 in 1 and then change channel on display to match if you have a display.  Also, you can try removing the hub from MyAcurite and then install it again.  That may also fix it.  Try that first.

RSSI is a poor indicator of distance as it is affected by other factors.   In other words, you aren't necessarily going to get a "4" close in and "1" far away.  

Regardless of the RSSI level, the data received is the same.  "2" is actually a fairly average signal quality.  It should be able to tolerate a drop to "1" without an issue.

However, if it is dropping even further, there is likely something in the area interfering.  It could be a physical issue like a leafy tree branch swaying in the wind near the "line-of-sight", a defective electronic device nearby (like a noisy lighting system ballast), or ham radio operations in the area (433Mhz is in the middle of the 70cm band allocated to amatuer radio and they are allowed to use much higher power signals)

Hello David,

Do you have the smartHUB connected directly into your router or are you using a switch of any kind? We recommend a direct connection to your router.  Please verify you are using the battery recommendations listed below.  Thank you.


Batteries:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

The batteries are Eveready Lithium Ultimate.  The date on the batteries is 12-2036.  Since they have a 20 year life, I assume they were made in late 2016.  They have been in service since March.

The hub is connected to a gigabit switch; all cabling is CAT6E.  Since the problem is the radio link from the 5in1 to the hub, I fail to see the relevance of the Ethernet connection.  In any event, as I already stated, I have tried other configurations, including direct to router, and I always get precisely the same signal strength.  That is the point that bothers me.  I have not tried putting the hub right next to the 5in1 (I would have to do that outside and have no access to the network).  But I have tried various orientations; closer to the station; further from the station; through only one wall;  through three walls; etc.  There is no difference in the signal strength.  Before you ask, I left the hub in each position for at least a day (I have been at this all week) and ensured that when I rechecked the signal strength that the update had been done.  I have also powered down and restarted the hub in each position.  There is never any change.

Hello David,

We do recommend the smartHUB is plugged directly into the router. We have found through testing & troubleshooting that some customers who have their smartHUB plugged into a switch will end up with an intermittent connection.  It sounds like this is what you are experiencing. Please plug the smartHUB directly into the router to see if this corrects the issue. The signal strength on My AcuRite takes 2 days to update so once you move the smartHUB or sensor you would need to leave it there for 2 days to see what the signal strength updates to.  We typically do not see customers with 4 bars on their smartHUB 2 to 3 is the normal based off of what I have personally seen.

OK, we're making progress.  I have done two things - I moved the hub closer to the weather station (one outside wall between them); and I plugged the hub directly into the main router.  After about 8 hours, the signal strength changed to 3 bars "Strong" and has remained there for a couple of days.  So I guess the problem is resolved.

However, I still have a question about the direct router connection.  I can understand that an ethernet switch might make reading the hub unreliable.  I do not understand how a switch could affect signal strength.  Would I be correct in assuming that I resolved (only) the signal strength issue by moving the hub; and that the direct router connection will (only) affect the reliability of reading the hub?

Hello David,

You are correct in your assumption. Plugging the smartHUB into the router is not going to increase the signal strength, however moving the smartHUB around can increase the signal strength. It does take 2 days to update. If you are getting good signal I would leave it where it is.
