Improving performance in Raspian

[kommando828]

After getting yasdi2mqtt up and running I added 3 other functions to the Pi to run at the same time in Node-red.

1 A simple set of Nodes to daily reset the energy counter to zero by writing 1 to register 507 on a UMG96S2.

2. Monitor the frequency and battery voltage of the Sunny Island and switch on and off loads with a Wifi Wemo socket switch.

3. Write data to a Modbus server on the Pi from the MQTT so a Solar-log would think it was a SI 8.0H-13 and data log.

Once I had that up and running I was getting network drops, running a ping to the Pi showed random time outs every 10 to 15 pings.

Step 1 was to check all the network cables and reboot all the switches and routers. This resulted in no improvement, pinging other equipment on the same router showed no ping timeouts so I instead set to improve the Pi performance.

Step 2 was to add privileged: true to the docker-compose.yml , this showed an improvement despite also changing the read frequency from 30 to 10.

Step 3 was to remove bloatware.

Step 4 was to boot into CLI

After these last 2 steps the ping timeouts stopped.
