FAQ
I already have hardware suppliers. Can I still use OpenCrab?
Yes. Keep your suppliers and bring device models, protocols and manuals for assessment. We adapt devices through standard capability modeling and the multi-protocol gateway, verify what can be integrated, then finalize the project mix.
Do devices need firmware changes for Apple, Google or Samsung?
For bridgeable devices, the OpenCrab gateway handles protocol conversion and Matter capability mapping; no sub-device firmware changes.
What does "five minutes" mean for the branded App?
It's the branding setup of Logo, name and domain on a ready App template. Standalone builds, app store review, domain setup or extra customization are arranged separately and not included.
Can devices still be controlled offline?
Local keys, direct terminal control and scenes that run on the gateway and have been configured and verified keep working. Cloud management, remote access and AI features using online models need a connection.
Can I get samples first? How do quotes and volume orders work?
Start with 1–5 sets of gateway and device samples. Quotes are based on configuration, protocols, quantity and delivery scope; volume purchasing follows validation.
Where do I onboard devices and use the platform?
ai.opencrab.cc is the enterprise platform and device onboarding portal for doc parsing, on-site teaching, product library and project management.
