Acurite Access Power Failure Memory

  • Updated 3 months ago
I have a 5 in 1 Weather station connected to the Acurite Access. We had a power outage and I thought the Access was supposed to store data from the weather station and broadcast it once power was restored. I checked my Acurite page and don't see any readings. Also how can I tell if the batteries are low in the Access?

According to this chart, a slow blinking blue and red means the unit is running on battery and that battery is low.

I disconnected it and it only flashed blue so I wonder why it didn't transmit the saved data.

"Flashed Blue"?  It has to be solid blue to transmit data, or running on battery with a "slow" blink and that would be very, very slow.

It "sounds to me" as if your Access is trying to connect to the network.  Several people have remarked on that.  One good way of figuring out if your Access is on the network is putting its IP address into your browser.  If it is up, you'll get a page showing such things as firmware version and Wunderground password.  Also, there will be a list of sensors that have wirelessly connected to the Access.

Figuring out the Access IP address can be problematic, but the "easiest way" is to configure a DHCP reservation in your router.  You still don't know for sure that the Access is using that IP address but to avoid conflicts where your router might allocate the same IP address to a different host, it is a good idea.

The Access sends out broadcast ARP messages about every 5 to 10 seconds.  Being broadcast, they travel everywhere on your LAN, including the wireless.  Look at your ARP table.  (On a Mac, you can use the Unix command "arp -a").  In the table will be the MAC address of your Access.  Chaney has been assigned the prefix 24:c8:6e:xx:xx:xx.  (The MAC is also printed on the bottom of your Access).  Put that IP address into your browser.  The page may not open the first time you try.  The Access isn't exacty reliable here.  But if you reload the page several times within 10 seconds, you should get the page to come up.  If it doesn't, then your Access is not on your LAN and so cannot send to your myAcurite page.

FWIW: I was debugging a problem where I received emails from acurite telling me that my sensors were off line (had not received data for 2 hours).  First, there is no missing data (I downloaded the CVS file today and there's data there for every 5 minutes for a week).

But in the process of doing the debug, I disconnected power and took the batteries out briefly to use a battery tester on them.  They showed they were fine.  I put them back, plugged the power in, the Access did its "pulse" thing.  Then went solid.

To back up what this means, my rain gauge (separate from the  5N1) batteries died over the last 24 hours.  I replaced the batteries and once the Access reconnected to the gauge, there were two data points available (between 5 and 10 minutes of data) in the CVS download.

It was only flashing blue when I was testing the unit by disconnecting the power to see if the batteries were low. The unit had a steady blue light before and after that. Prior to this we had a 17 hour power outage. Also it has been communicating ever since the power was restored, just not any of the data during the outage.
