Greetings!
I'm pretty new to this automation world, but since a month or so playing around with Home Assistant and Node-RED in my home on wheels.
I installed on a Raspberry Pi 4 4GB, Home Assistant in Docker and first also had Node-RED in a container, but didn't like that I can't write files outside of this container. So I installed Node-RED with the install script locally. Added node-red-contrib-home-assistant-websocket and installed with HACS the connection according to: https://bit.ly/3tductt
All on the same Pi.
Since I'm really not a programmer, but very enthusiastic learner, I asked around on the web how people got info's through.
A nice thing I like is temperature and locations, So I wanted to get my GPS location to be updated as my home location.
My electrical system is only made out of Victron chargers/inverters and a CCGX with an USB GPS connected.
Unfortunately the GPS is pretty unstable lately, but a new one is on it's way (from Germany to Greece)
Now the issue:
I'm getting via MQTT an message from the CCGX with my location.
Since I'm not able to write a javascript, I'm "Changing" and "Joining" the message until it's ready to send to the homeassistant.set_location service into Home Assistant.

Now the strange thing happens:
My Memory (RAM) is getting flood.
I found this out, because I had a couple of times a complete freeze of my Pi.
I narrowed the problem down by not running Node-RED (but with MQTT being on via MQTT sensors in Home Assistant), and then deleted this flow.
Without this flow all is fine. Memory is nice and stable.
I know this flow can be optimized with a function node, but I've no idea how...
Anyone out there who can help?
