Output files error

Hello. When the script is running, it outputs files named meshtastic.prom.xxxx , where xxxx is a number This filetype is not valid for node-exporter. I tried to remove the $$ in this line below, and now it outputs files just named meshtastic.prom, and node-exporter reads it. <img width="831" height="167" alt="Image" src="https://github.com/user-attachments/assets/f1bc4a63-5659-4065-8a0e-32bd0a080520" /> Im using version 0.98 from github
