What people report
Plugin for Siemens S7 style PLCs; PRs add many accessory types (thermostats, blinds, locks, humidifiers, leak sensors, fans) rather than specific hardware models.
Gathered from the plugin’s GitHub issues, pull requests, discussions, wiki and docs, and from r/homebridge. These are individual reports, so check the linked thread and the date before you buy.
How it connects
Local
snap7 PG/OP communication to PLC IP, polling plus HTTP push/control
You’ll need
- PLC IP, rack and slot

In ReReHome
Whatever this plugin publishes reaches Apple Home as a normal HomeKit accessory behind your Homebridge bridge, so ReReHome shows and controls it like any other.
Bridges get their own settings page listing the accessories behind them.
Caveats from the README
- S7-1200/1500 need Snap7 settings
- Home app only refreshes values on open unless polling or push is enabled
- May need more connection resources in TIA Portal
