Radar Distance Monitor
committed
Add multi-host support with chip detection and improved logging
Features added: - Support for 1 to many hosts (flexible configuration) - New HOSTS list format alongside backward-compatible legacy format - Automatic radar chip detection and display (model + ID) - Flexible command-line arguments (--host, --user, --password, --command, --tag) - Clean logging (no false error messages for initialization output) - Enhanced legend with chip information - Updated examples for single and multiple host configurations Breaking changes: None (fully backward compatible) Configuration: Both legacy (HOST1_CONFIG/HOST2_CONFIG) and new (HOSTS list) formats supported CLI: Both legacy (--host1, --user1, etc.) and new (--host, --user, etc.) arguments supported

Example configuration file for radar distance monitoring.

Copy this file to config.py and modify the values for your setup.

6+
Two configuration formats are supported:
7+
8+
1. New HOSTS format (recommended) - supports any number of hosts:
9+
Use the HOSTS list below for flexible configuration.
10+
11+
2. Legacy format (backward compatible) - supports exactly 1 or 2 hosts:
12+
Use HOST1_CONFIG and HOST2_CONFIG (commented out below).
13+
14+
Choose ONE format - do not use both at the same time.
