Access off line for hours at a time

  • Problem
  • Updated 4 months ago
The new Access hub continues to be a very frustrating device. Periods of time it will function as expected. Other times - like now! - it will be offline for hours at a time. It does not remain reliably connected over periods of time. This is unacceptable. Right now it has been off line for over 9 hours. The Dashboard is reporting excellent signal but status "OFFLINE".  The Access status light is solid blue. Weather Underground is reporting no data for 9+ hours. I can see the Access mac address on my router (direct connected). The Access IP is reachable. This same thing happened yesterday, and after 11+ hours was spontaneously back on line. Is there something going on with the AcuRite servers or is this an Access issue? [see attached screen shots]

Michael,

Go back to the Access internal web page for a moment.

What does it say about sensor signal levels?

Is it showing correct UTC time?

Hi John. Here's a screen shot:

OK. That looks correct. Puzzled.

Michael,

When it comes back online does it back fill missing data to MyAcuRite?

I can't confirm. When it comes back up today, I'll update. Thanks!

I agree. This is puzzling! But the good news it popped back on. I did not intervene (no reboots, etc.). Here's the My AcuRite screen. Not really back filling: It connects the last reading ( approx 2300) to the current one (approx 1000) and draws a straight line. See below:

From what you've posted so far it seems that Access is running and hearing your sensor and it knows what time it is but data packets are going nowhere. It's as if it has fallen into battery backup mode without fully realizing that it has done that, as the blue light would blink every few seconds to acknowledge that mode. If it back fills data when it returns, that theory may have legs. If not, something else is amiss. Not normal, regardless.

Oh! Just saw your update...

I put fresh batteries in. If it does it again tonight, I'll check again for the back fill. In the meantime, it remains back on line with updates to WU and My AcuRite in an online status.

Thanks for your input. I'll be curious what AcuRite has to say about this.

Its interesting that you can pull a page out of Access, and also see it in your router list while data is otherwise going nowhere. It seems like the problem is upstream of your router. If it were just MyAcuRite though, why would sending to WU go dead?


Yes, it will be informative to see how this gets resolved.

Indeed. I agree: My first thought was "AcuRite Server." The fact that the Access is clearly visible on the home network seems to point upstream. The 5 in 1 is "broadcasting" to the base station in the house. I'm no network engineer, but as I see the "schematic", the blue is good, but somewhere upstream (e.g. AcuRite Server?) appears to be not so good, which I've drawn in red, at least during the extended downtimes I have been experiencing (pardon my crude drawing!):

Michael,

Access sends directly to WU. MyAcuRite passes your WU credentials to Access, and from that point is not involved in WU traffic. Puzzling.

OH! Now this is puzzling.

John,

Do you know what causes the 5-n-1 to have poor singal strength at 1 on the access ( when is next to each other) but have full bars on the display when its the scensor is installed outside?

That's because the displays consoles show "signal strength" in a different fashion than they do on a SmartHUB or Access.

The Access and SmartHUB have a radio chip that provides RSSI information, much like you would expect from a cell phone or wifi indicator.  Even if you have only 1 bar, it's still getting all the data through.  More bars are obviously better for a more robust signal.

However the displays do something quite different.... they start out with full bars, then subtract a bar each time a scheduled radio packets is missed.  So if you ever start losing bars on a display, you know you are losing data.  The more bars missing, the more data being lost.

In short, the bars on the display and Access aren't really comparable.

Darren,


I am currently running 3 Access devices, in two locations, and have an accumulated running time of about 8 device-months on them. All of them are showing excellent signal strength from all of their sensors. Some sensors are quite far away and signals must pass through multiple walls. In one case I can get a signal over a 400-ish foot distance, but that path is ridiculously favorable.


Interference is the thing that I find messes the most with Access' receive capability at my installations. If I position Access too close to any WiFi equipment, it tends to lose my sensors. I keep it at least three feet away, more where I can.


The other day my display signal strengths went wildly erratic, and a checkup on my two local Access splash pages showed signals had gone to zero for all sensors. Yellow bars started showing on MyAcuRite. Then I noticed the guy parked in front of my house in a gas company truck, using his two way radio. When he pulled away, all was good again.


If I move an Access into my kitchen, I find that my bay of ceiling LED lights generate enough noise that I see diminished signals. Other LED's, elsewhere in the house, pose no problem.


I have long wondered about high speed DSL as an interference source, turning phone lines into broadcast antennas. I have no experience with that and Access, but even entry speed DSL noise has made some ham radio activities all but impossible at one of my locations.


When Access encounters strong interference, the receiver chip inside tries to protect itself by cranking down its signal gain. All sensor signal levels decline as a result.


So in my experience, it has been interference of one type or another that has gotten in the way, and in this modern world, that is not in short supply. You may have a defective receiver. That can't be ruled out. Hopefully I have given you some things to think about and try.

This morning was the first time I had the access up and running. But the devices were side by side. When I put the sensor back outside (max 50 feet) the singal went down to 0, then lost it off the ip webpage all together. But the display was functioning normally. I’ll try a few more things but i’m not getting my hopes up. Thanks for the info John, I appricate it. If you can think of anything else I can try, let me know. I’m all new to this.

Same issue (Access blue light on solid but no data to "MyAcurite" on computer) here.I have two sensors, one shows "Strong" strength and "Offliine", the other shows ""Weak" and "Offline".  My color display has never had a problem displaying the data from the Weather Station.    Access unit is less than one month old and was purchased because the original clam-shell SmartHub showed weak signals for both sensors.  Access unit originally showed "Strong" and "Excellent" signal strength for sensors.   
Tried cycling power on Access and then Access and modem, with same result.  All other devices on modem and router working fine on the internet.  Swapped cable with same result.  Modem Ethernet light is solid on.
Looks like the new Access unit is defective.
