Need very basic guidance on what to put in config.json for radio control

Brand new to pat. Not brand new to Winlink, VARA or hamlib.

I've got 0.12.1 installed and basic configuration done. Web page loads fine.

I want this to work with VARA, which is installed and working fine with Winlink Express.

In config.json I see

"hamlib_rigs": {}

and in the vara section

"rig": "",

I assume these both need some entries to make rig control work, but I can find zero guidance anywhere on how to set this up.

For reference my hamlib radio type is:

2048 FlexRadio/ANAN PowerSDR/Thetis 20210605.0 Stable RIG_MODEL_POWERSDR

and I want to use the Hamlib TCP/IP method on

to pat-users are the instructions you were looking for.

The rigs is a map of named entries, so you define your rig with whatever you want (below, I'll use "flex_rig") and then you tell the vara section which key to look up. So:

  "hamlib_rigs": {
    "flex_rig": {"address": "localhost:1881", "network": "tcp"}
"vara": {
    "ptt_ctrl": true,
    "rig": "flex_rig"
