Sensor Goes Offline Failure Definitely a HUB or Sensor to Sensor interference issue

Have had the system now for a month and over that time now I have had 6 random sensor failures of three different sensors.

For a different reason we turned my BLUE lights off for 6 days, per a request from Acurite. I do not know what this does to the HUB but R&D Knows. During those 6 days I had NO sensor failures. Seven hours after I turned the BLUE lights Back on this morning I had a random sensor failure and it did go RED and OFFLINE.

In all 6 cases a router/Modem reboot did nothing to fix.

Here is the disturbing Part Please look carefully. I could recover all 6 failures without ever touching the failed sensor.

  1. When I state signal level of 1 to 4 I am refering to the HUB values.
  2. Failure is defined as the sensor goes OFFLINE and turns RED.
  3. Even though a sensor is RED I look at the time stamp and when that starts updating again I know the sensor is now fine again. In all cased they eventually turn GREEN.
  4. ALL batteries were brand new 1 month ago.
  5. ALL sensors were a solid 3 or 4 signal.

Here is the recovery method summary.

Failure 1 (2 Hour duration) - Reboot HUB Fixed by second MyAcurite refresh.
Failure 2 ( 1.5 Hour duration) - Took batteries out of the three good sensors Fixed by second MyAcurite refresh. Coincidence? I don't think so probably removes interference.
Failure 3 ( 1 hour duration) - Reboot HUB Fixed by second MyAcurite refresh.
Failure 4 (3 hour duration) - Reboot HUB Fixed by second MyAcurite refresh.
Failure 5 (1 hour duration) - Took batteries out of the three good sensors Fixed by second MyAcurite refresh. Coincidence? I don't think so probably removes interference. Look below as what fixed that failure was overpowering any interference by moving sensor near the HUB re-connecting then moving it back. I WILL admit Taking all of the batteries out may not eliminate interference but rather removes data load on the HUB so the problem can be the HUB problem.

The above were all before we Turned OFF the BLUE lights. I do not know if its coincidence or not but for 6 days in this "BLUE light OFF state" I had NO failures. I do not know how many days elapsed between my 5th failure and the start of the BLUE lights off test.

I turned the BLUE lights back on this morning and 6 hours later I had my first random sensor failure in just over 6 days. Coincidence or not LOOK AT THE RECOVERY MODE.

I checked the HUB and the failed sensor was in fact missing. It was at a 3 level signal for the entire 6 days. All sensors and the HUB were left undisturbed the entire time. My Router/modem was rebooted many times for other reasons during this time. In all cases all was well after the Router/Modem reset.

Failure 6 (1.5 hour duration) - Nothing will bring that sensor Back online. Now I will move it closer to the HUB and force it to "bind". Within seconds the sensor was connected at a signal level of 4. Now its moved back to its original location.

The sensor eventually went GREEN and is logging Data again now for just over an hour. ALL four sensors are now just fine.

Hope this will help the R&D group in some way. I have spent upwards of 30 hours on all this. I have until end of today to request a return so I will have to Give up and return. I really like the system just not reliable enough yet for at least my needs. I will pack it up tomorrow and will let the system run until later. Will see if it fails in the next 6 hours. Maybe the BLUE lights off did do something just not what was expected.

DISSAPOINTED I thought I finally found what I needed. GOOD LUCK and I mean it !!!! Jennifer and others thank you you tried and so did I.

Here is the Chart for the Failing sensor. You can see It stopped working. Came alive for 1 point and then failed again. Its now still working as you can see after I moved the sensor as described. I did not try to explain the single point (YES the sensor did go GREEN) and then immediately failed. I felt explaining that one would be too difficult but I could try if you want.

Jennifer: Thank you and everyone for all the help. If for any reason R&D or anyone else there wants any additional information with any of my posts to date I would be glad to answer just e-mail me.

All the best

Richard,

Sadness :-(

Like you, I faced a stay-or-go decision. I chose to stay.

My system is serving me well enough that I was happy to purchase some additional sensors for it, and will likely get a range extender as well. You know that I have been critical, even prickly, about some aspects of the hub technology. Overall, I find much more plus than minus here, and I am confident that the minuses will be worked out. For example, my spot check of 12 recently rained-on WU stations is hinting to me that LM and his Platform Solutions team have the rain reset issue nailed, and will soon be ready for the next challenge. Look at these products again, for the next season.

See you soon...J

I will be back and yes that my plan to come back for next winter. This year I only have 2 weeks away but next year may be 3 months. My needs are based on having a system that you never have to physically touch for a few months. Two days ago I had a failure that depite my ability to remotely power cycle the HUB and/or Route/modem I was only able to recover by direct physical intervention. So reluctantly I ran out of time and returned. I have a high bar need. It is a very nice system. I enjoyed your comments !! Repeaters can help as long as they are not also picking up interfearence as well. I almost decided to just have two Hubs so all my sensors plus the few more I wanted to add would have a 4 level signal. I would also have "redundancy". I decided to wait they will get better. I just could not justify the cost for now.
