Overview
Is it a coincidence that many utilities have issues collecting data to the cloud at lift stations and wastewater plants? Nope. Most of these sites are strategically located at low elevations to take full advantage of gravity. Or maybe your water plant was built as a big giant steel box and you can't get coverage in there. Not a problem. As long as you can bring up the site you are collecting data at when you have some sort of data connectivity, you can collect data while "offline" and then when you're back online, you can save and sync everything back up to the cloud.
How does it work?
It's pretty simple (for you anyhow)...when Waterly tries to save your work, it first checks if it can "phone home." If it can't see the database to save the data, it just gives you an indication that it didn't save the data points with a red box in the upper left of the screen. Your cells' backgrounds will stay yellow (unsaved) while you collect data to remind you that you are offline. You can either leave that red box up or hit the X in the corner to close it out and keep on collecting data. Once you are done collecting data AND you are back in coverage (WiFi or Cellular), you can hit the Save button in Waterly and your data will save, sync, and give you that nice green box saying everything was saved.
In the rare event that your data doesn't ever save (yes, "stuff happens" from time to time), we recommend you take a screenshot of your screen of data for later. We know it's not ideal, but when it happens, it's better than going back a second time to collect data again.
Example Video
Here's a video showing how it works when the device is disconnected in the middle of doing rounds. Note that the data entry screen was already pulled up before data was disconnected.
