I’m trying to get a good balance between polling my sensors frequently enough, and power/data savings. (This is with an electron.) Currently, I take a sensor reading, decide whether to publish or not, then go to sleep for enough time to wake up at the next minute. I.e., poll at 12:00, 12:01, 12:0…

First, there is no keep alive while sleeping, so I changed the topic title, since you were not actually asking for that anyhow. AFAIK keep alive only happens if required when there is no other traffic happening to keep the cell connection open. The UDP based communication with the cloud on the oth…

ScruffR, Thanks for changing the title… I was still half-asleep when I wrote it this morning, and it didn’t make much sense. I seem to be using way too much data for keepalives only every 23 minutes. Right now, I have my sensor disconnected, so the code that reads it should timeout and report an…

If you want to cut on data consuption, you’d need to take control of the cloud connection yourself. You may want to call Particle.disconnect() before going to sleep and only reconnect if required, otherwise you’ll always have the cloud handshake on wake too, even if you don’t intend to use it. The…

So there is no way to enter and exit sleep without either: Disconnecting from the cloud to avoid data usage? or Remain connected to the cloud, but handshake on every wakeup? I was hoping to find a happy medium where I could frequently enter/exit stop-standby mode while not using data (aside from …

Disconnecting from the cloud does not immediately disconnect you from the cellular network, and hence you will not use the 6K cellular renegotiation when you wake and will also not have the cloud handshake with all the function/variable/subscrption update between device and cloud. So that actually…

I assumed (I guess incorrectly) that disconnecting from the cloud would mean that I have to pay energy and data for cellular renegotiation and cloud handshake when I later decided to re-connect. If this were true, then I would have to decide whether to disconnect based on whether I expected to tran…

[image] JeffInCO: What you're saying is that there is no energy/data penalty to disconnecting and reconnecting. Not exactly. What I was saying is that you will always have some data/power impact when reconnecting to the cloud, but that you would have on every sleep-wake cycle without disconn…

@ScruffR , the keep-alive won’t work when sleeping. @BDub will be writing some docs for the power/data saving modes. Bottom line is you can save on data or you can save on power but you can’t do both together without some caveats.

Hence: [image] ScruffR: as long as you are awake at least once in 23 minutes.
