Or, heaven forbid, your internet connection is disrupted, delayed, or goes away for a few minutes. Sometimes we wonder how did we ever live without the internet always available?
In the end, some things are just beyond your control. However, this possibility of a temporary loss of internet connectivity is a big deal in Industrial IoT, where your organization is remotely monitoring sensors and critical assets that are critical for your needs.
How do we fix it?? You’ll learn just how in these here step-by-step tutorial instructions.
This write-up is about the Tools.Valarm.net / Valarm Tools Cloud Websockets feature that gives you the power to store data locally, to local memory built in to your data loggers on your Yoctopuce sensors, so that just in case your internet connectivity goes out for a little bit (e.g., 3G GSM mobile cell network connection might be dodgy or spotty) – you won’t lose your precious IIoT sensor information! Your sensor hubs will retrieve and upload all of your missing sensor data the next time connection is available. Note that this feature is in early alpha and beta testing, so if you don’t have access, and want to test it out, knowing that there are risks involved, then please don’t hesitate to contact us at Info@Valarm.net.
You can use this feature with sensor hubs that connect to Tools.Valarm.net via:
These first steps for creating a new device are also more elaborately covered in the How To Use Valarm video.
Then paste that routing code into your outgoing callback configuration screen in virtualhub. Make sure your sensor hub is connected to the internets and click Test Now to verify that everything is A-OK.
3. Under Configure Hardware -> Configure Yocto Hub set up your sensors and map them to the sensor columns / fields you want. Note that you can later remap / rename / set up aliases following these instructions.
4. Set up your Hub Config tab to the post interval you want. Here we’ve set the post interval to 120 seconds. This means that your sensor hub will check in with Tools.Valarm.net every 2 minutes and upload what needs to be uploaded. Even if your internet connection temporarily disappears your sensor hub will continue trying every 2 minutes until the end of time or the moon crashes into the earth.
5. Now we’ve got Industrial IoT sensor data flowing from the field to Valarm Tools Cloud / Tools.Valarm.net.
Go to the Advanced Config tab like you see in the screenshot and click the question mark ( ? ) buttons to get help and detailed descriptions for all of the settings.
You’ll see the options for:
- Setting the sensor hardware data recording rate
- Setting the Interval for how often event collection happens
- Applying averaging to recorded data
The help menus for these options are included in these screenshots for your convenience so you can learn more about exactly what they do.
8. With the settings above we’ve set the post interval to 120 seconds / 2 minutes so the sensor hub will check in every couple minutes. In this next step we’ll set the data recording rate to 2 times per minute. This means sensor data will be written locally to the sensor module (e.g., Meteo or Light sensor) twice per minute a.k.a. every 30 seconds. Think of it as how often a backup is being written locally to the memory on the Yoctopuce sensor module.
9. We’ll set the event collection interval to 60 seconds meaning an event or row of data in Tools.Valarm.net is made every 60 seconds or each minute. So you’ll have up to the minute sensor data readings. Now, if the hub tries to check in every 2 minutes it’ll have 2 rows / pieces of data to send to Tools.Valarm.net. In the case that internet connectivity is lost for some reason, all of the data is saved locally and the hub will upload all of the historical data and backfill the Valarm Tools Cloud data log next time the internet is available during 1 of the sensor hub’s routine 2 minute check-ins to Tools.Valarm.net. Make sense? If not, please don’t ever hesitate to contact us at Info@Valarm.net if you’ve got any questions!
10. Now that we’ve configured the datalogger settings click the Switch to Websockets button, say OK, and save! That’s it. You’re good to go. Let’s test it out next after we’ve saved and switched to Websockets.
We can take the WiFi hub offline by connecting it to a bogus WiFi network ‘abc’ that doesn’t actually exist where we’re at. We’ll leave it like that for a few minutes, then connect it back to the internets with the real WiFi network and see the sensor data backfilled from the data logger once a connection to Tools.Valarm.net is detected and restored.
12. Now a few minutes later at 15:16:30 we reconnect our sensor hubs to the interwebs and wa-la! like magic the historical data is filled in from the data logger. It’s like we never lost connection to the internet. Hallelujah, none of our IIoT remote monitoring info has been lost! Excellent. All of the data is there from each Event Collection Interval, which we set to 60 seconds above, so we’ve got all our minute by minute sensor measurements. Nothing’s lost.
