Mitsubishi heat pumps,
straight into HomeKit.
An ESP32 in the CN105 port, talking HomeKit on its own. No Home Assistant. No ESPHome. No bridge server.
No app, no subscription, no account. Ever.
How it compares
The DIY route
×Always-on hub or server in the loop
×Flash it yourself, write a config file
×Reaches HomeKit through a third-party bridge
×Two systems to keep updated
×Goes dark when the hub reboots
Kiri Bridge
+Nothing else to run
+Pre-flashed, configured in a browser
+Speaks HomeKit directly
+One firmware, OTA from the device
+Online as long as the heat pump has power
