It has been a delight to benefit from Cerbo GX temperature controlled relay functionality. I'm using firmware version 2.92, where settings can be adjusted without too much of a hassle.
I would like to learn more about the interplay between the VRM RuuviTag pane, the sensor and Cerbo CX relays. This is how the device shows up on the dashboard:
The temperature readings on the top (and other rows on the RuuviTag pane) update frequently without any user intervention. However, we are told that the reading was 'Last updated: 3 minutes ago'. - Can anybody explain what this last row means?
