Will OmniQu work with your controller?
If your controller speaks Modbus or BACnet, over Ethernet or RS‑485, OmniQu can read it today. Below is exactly what we read and write, what runs in real buildings, and what we don't support yet.

Points come from your documentation and are reviewed by people. Remote changes are switched on per site, after commissioning and your approval.

Figures as of October 2026, and growing. We don't name controller brands, so that customer sites can't be identified. Ask us about yours.
Equipment we already know.
A definition names every value a unit sends, grouped by component, and says which ones may be changed. For these types we start from a ready one, not a blank page.
