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 ;)

Ok, that's interesting. Manual says:

Log interval

15 minutes

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.

I just checked, and you are right @Boekel as so often. I delete my wrong answer...

It would be nice if it had an option to save up the data and sends it at longer intervals.

Mobile data connections often charge a minimum (like 100KB) per connection, that's what makes it expensive to use the 1 minute option.

@Boekel How does a 1 day setting makes sense then? Not really?!?

@Boekel

thanks!

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

if you want more precise longtime logging i recommend external modbus logging in own Database. We acuall log 5 sec interval the importend data to a own mysqlDB
