RuuviTag in Cerbo GX VRM dashboard

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?

That was the last time vrm received information from the cerbo. You can change the time interval.

I see. And the time interval of VRM log registrations can be adjusted in the remote console:

Device List > Settings > VRM online portal > Log interval

This means that the Cerbo GX and the web user interface talk directly to the bluetooth sensor.

This would perhaps indicate that there could be a better place to signal VRM update events than in the RuuviTag temperature pane. What about placing this VRM logging information on the status row somewhere among the 'Last updated:' and 'Status:' readings. Wouldn't that be a more appropriate place?

Can the Ruuvi be used instead of Battery Sense and so on?

I was hoping to add these sensors for battery monitoring and alarming too ;-)
actually I do, but I can only use email / VRM alarm, no actions

This topic was started to discuss the essence of the last line on the current RuuviTag VRM pane. It turned out that the 'Last update' value actually has little to do with the RuuviTag. Suggested that VRM update info should be placed where it seems to belong: On the VRM status row. - Any response to that gui modification wish?

Your question relates to warning and alarm functions. Would it be better to start a new topic or to move your question to one related to the solution you are looking for. Would you like temperature values to trigger a relay? There are a number of related topics in the Questions & Answers space...
