The official companion application for openHAB - an open source home automation system. The open Home Automation Bus (openHAB) project aims at providing a universal integration platform for connecting home automation technologies into a single intelligent system. With more than 3000 things that openHAB can connect to, there’s virtually nothing that can’t be integrated. Its advanced rules based architecture allows complete automation using several popular scripting languages (Java Script, Ruby, Python, Java, RDSL, and more ) as well as visual rule designers using either drag and drop interfaces or simple “If / Then” forms. The new openHAB UI allows users to easily build beautiful interfaces customized to their needs. openHAB is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic. Key Features: * Integrates seamlessly with your own openHAB UI (Main UI or sitemaps) * Control everything on your openHAB server directly or remotely through the free openHAB Cloud service (https://myopenhab.org) * Enhanced push notifications with media from openHAB Cloud and the openHAB cloud binding * Apple Watch companion app * Natively supports both iPhone and iPad Make openHAB the central integration and control point of your Smart Home.

Verdict

The call

The clearest difference is rating: openHAB at 5.0 against NoMachine's 3.0. openHAB also leads on update cadence (every 3 weeks vs every 7 months). NoMachine's advantage is ratings volume (126 vs 3) and iOS requirement (9.0 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

openHAB holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: NoMachine has 126 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 37% of NoMachine's written reviews are positive against 33% of openHAB's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NoMachine ships an update every 7 months, openHAB every 3 weeks. The most recent releases landed on November 1, 2026 and November 4, 2026 respectively.
