Stops approximately once a week Moderators: adafruit_support_bill, adafruit

Hello, Feed stops about once a week, requiring me to sign out and then sign in to get it working.
The blue dashes across the top turn red. Is this normal or is there something I can do ?
Thanks Much, T

Hi T,

The feed stops working, or are you logged out of the Adafruit IO Website? Do you have a computer/display monitoring a dashboard?

Hi brubell,
Thanks for responding.
I'm using Chrome on the desktop of a windows 10 machine, logged in all of the time.
However, the machine is set to go to sleep. Normally upon wake up, it's all there and
functioning properly. I do have a Huzzah esp 8266 on a timer that reconnects every
10-12 minutes sending data. It's more of an annoyance than a problem.
Thank you very much for any advice.
T

Can you post the code that's running on the ESP8266?

[tj1]

Thanks for getting back. I think this is it, (had 5 or 6 efforts to get it working initially,) (forgot to delete
ones that didn't work.) I'm not good with coding
Thank You Very Much for your time.

I feel this is the offending code which disconnects you from IO, at the bottom of the loop:

Code: Select all | TOGGLE FULL SIZE

 // Repeat every 1000 seconds (16.6 min.)
  delay(1000000);


The code at the top of the loop pings Adafruit.IO, this keeps it connected to the service:

Code: Select all | TOGGLE FULL SIZE

  // ping adafruit io a few times to make sure we remain connected
  if(! mqtt.ping(3)) {
    // reconnect to adafruit io
    if(! mqtt.connected())
      connect();
  }

Since you're delaying for 16 minutes, the esp might become disconnected as this code doesn't run, and therefore doesn't ping the service that it's connected.

You might find success with using the deepsleep example: (https://github.com/adafruit/Adafruit_IO ... psleep.ino). It'll put your ESP into a special type of operating mode for low power consumption (which you'll want if you're reading every 16 minutes). When it restarts, it'll reconnect to IO (instead of connecting once, and attempting to ping, even if disconnected)

Thank You VERY MUCH Brubell !
I'll give that a try.
