Greetings, I had a quick question. I’ve been assigned a project that involves using Ignition Edge. They want to historize humidity and temperature data.

Ignition Edge comes with its own Historian, but according to the documentation, it only stores data for up to 35 days. They’ll probably want to view data from the previous month or even earlier.

From what I understand, if I store a data point today, it will automatically be deleted from the database after 35 days.

Please let me know if I’m mistaken about that.

Yep. If you want data retention, you need to have a full gateway.

Or sooner if it becomes the 10million and 1 datapoint before 35 days is up. Edge is meant to generally be used in conjunction with a full gateway.
