What changed, version by version.

Rotorloop is a development preview. These versions haven't run on a customer site yet. Each entry says what was built and how it was checked.

BACnet driver. Finds controllers on the network, including MS/TP controllers behind a BACnet router. Reads names, units, states, maker and model. Writes at a safe priority, and hands control back when a change ends.
Modbus driver. For meters, boilers and plant equipment, including serial devices behind a gateway. Every point that may change needs a rule for handing control back, otherwise it stays read-only.
Equipment tab. Every device of any kind in one list, with on/off, mode and number controls.
Smarter matching. BACnet rooftop units now show under Rooms automatically, when the point names and units agree.

56 automated tests.
End to end against a simulated BACnet controller and a simulated Modbus boiler and meter.
Phone layout.

Admin area. Add people and set their roles, manage access keys, add and revoke site Connectors, and choose per point what can change, with limits and a longest hold.
Activity log. Searchable, filtered by outcome, with older entries on demand.
Role rules. Only owners grant admin. Nobody changes their own role. There's always one active owner.
Safety fix. If a point is made read-only while held, the hold ends at once.

31 automated tests, plus every role rule tested through the API and the browser.

The app. Rooms colored from cold to hot, the draggable dial, hold times, back to schedule, all readings, live updates, phone layout.
The Connector. Runs on site, dials out only, reconnects by itself, and keeps hold timers through restarts.
The safety layer. Read-only by default, limits, rate limits, minimum on and off times, a life-safety block, safe priorities and required end times.
A simulated building for development and demos.
