IoT messenger platform combining team collaboration with remote device control
Semilimes is a unified IoT messenger and collaboration platform that bridges the gap between human communication and connected device management. It combines messaging, group chats, channels, and video calling with the ability to monitor and control IoT devices through conversational workflows — all from a single app available on iOS, Android, Web, and Desktop. Designed for both individuals and organizations, Semilimes lets users create reusable templates for messages, forms, and automation buckets, securely share device access with team members, and discover nearby users through location-based networking. Developers can tap into a full API ecosystem to integrate custom hardware or third-party services, and cloud service instances for Node-RED, MQTT, Python, Node.js, and Ollama LLM are available directly through the platform. Semilimes operates on a transparent, usage-based freemium model — users start with 5 GB of free storage and pay only for what they consume beyond that, with degressive pricing tiers that reward growth. This makes it an accessible entry point for hobbyists automating a smart home, and a scalable option for teams managing fleets of connected devices.
