log interval 1 minute?

I read some posts and manuals but still dindn't fully understand what log interval setting finally means. ( I am on 70MBit Internet link, so not worried about the traffic, however I don't want to keep the VRM portal busy uneccessarily.

Manual says:
Set to anything between 1 minute and 1 day. Choose longer times on systems with an unreliable connection. Note that this setting does not affect reporting problems and state changes (bulk → absorption) to the VRM Portal. These events initiate an immediate transmission of all parameters.

Is this only the interval for transmision of parameters to VRM portal, or is it also dictating the real data logging interval, i.e. how often data is captured by the VENUS GX ?

I can tell you that when interval is set at 10 minute, on the VRM portal info is visible per 10 minutes. So it doesn't save the data and sends it all at once every 10 minutes.

@Boekel Really? I did not come to the same conclusion, but I only switched between 1 and 5 minutes.

yes, see screenshot. I've put this system on 10 minute inverval because it is in Belgium with a Dutch 4G connection, a 1 minute inverval was quite expensive ;)

So until I have the local Modbus logging I'll stay with 1 min.

I have the sim chip lte module for my cerbo. It was logging approximately 250mb per month doing 1 minute intervals. I now found a sim company 1gb for 12 months $20cdn. If I bump mine to 5 minute intervals it should use 50mb a month / 600mb year. I just wish there was a real-time when logged in option is all I care about.
