July 12, 20223 yr Hello Everyone, Has anyone ever recorded or monitored the data usage of the data logger of the growatt inverter? I know it is low and nothing to worry about but recently I have changed the interval from 5 min to 1 min and I want to know and see the difference.

A general idea also helps.
July 12, 20223 yr Some comparatives here Solar Assistant - providing 1s realtime data via MQTT to my home Assistant instance so lots of data. Also includes downloads of new firmware that i did - 452Mb Comparatively - Solarman providing the standard refresh interval to the cloud - 668kb

You need to enable mqtt mode to send data to another queue of your choice (eg Home Assistant). On my RPI3, Solar-Assistant with mqtt enabled. sends mqtt data set approx 45x per minute -> 1.3s update frequency. This may be a speed limit of the RPI3. Would be nice to have a setting that allows us to select an update frequency, eg 5s or 10s If you enable mqtt, then it sends to another mqtt listener - normally on the LAN.

If it operates in a local mode or sends the data to the internet/cloud, the size of what should be send is the same either way. It may be slightly larger over the internet since the message needs some headers and other stuff depending on which protocol was used to send these data. Anyway, thanks for your reply you and @mzezman which provided me with some info. and data regarding this matter.

Anyway, thanks for your reply you and @mzezman which provided me with some info. and data regarding this matter. Solar Assistant stores all data locally on the Raspberry PI using InfluxDB. No data is sent/stored in the cloud. 1) This is a great privacy feature 2) Not affected by internet outages 3) No data missing because in internet line is down SolarMan Dongle/SunSynk Dongle/CloudLink send data to the cloud and store data in the cloud. If you have Home Assistant, you can can integrate Solar Assistant with Home Assistant via the mqtt feature. Only when mqtt is enabled, is data sent real time using mqtt from Solar Assistant to Home Assistant. You normally run Home Assistant locally on your LAN. Solar Assistant does have a "proxy" feature that allows you to connect via a URL and view the data on your local Raspberry PI when you on the road.

Thanks for the explanation but my point still stands. What I meant was that the collected data using the solar assistant or any type of dongle have a fixed size wherever it is stored locally or in the cloud. So sending, downloading, reading the data, and also sharing them can't possibly take more than their original size. Less is possible depending on what you want. In the end of the day - despite any security, privacy, or internet issues - the data have a maximum of a fixed size and they can't take more.

Solar Assistant connects to Inverters & Batteries via RS485/RS232/Modbus so there is no WiFi / LAN / Internet / cloud tcp/ip traffic during collection.
