RFXCOM RFX-433EMC: The ultimate universal 433 MHz bridge with Extended Motor ControlDo you have roller shutters, awnings, wireless switches, or weather stations operating at 433.92 MHz? Think Somfy RTS, Cherubini, Ozroll, Brel, KlikAanKlikUit, or Oregon Scientific? With the modern RFXCOM RFX-433EMC, you get a powerful universal transceiver to seamlessly, stably, and fully locally integrate this 'legacy' and modern equipment into Home Assistant or Domoticz.⚠️ Note the frequency (Selection Guide): This is the 433.92 MHz version with Extended Motor Control. Are you looking for the transceiver for mechanical ventilation (Orcon, Itho Daalderop, Zehnder), Honeywell thermostats, or Kopp Free-Control (868 MHz)? Then check out the RFXCOM RFX-868 Transceiver.Selection Guide: 433.92 MHz vs. 868 MHzChoosing the correct frequency is essential for the proper functioning of your smart devices. The comparison below helps in making the right choice: Feature RFX-433EMC (433.92 MHz) RFX-868 (868 MHz) Primary application Awnings, motors (EMC), KlikAanKlikUit, weather stations, sensors Mechanical ventilation, HRV, Honeywell heating, Kopp Supported top brands Somfy RTS, Cherubini, Ozroll, Brel, MotionBlinds, KaKu, Oregon, La Crosse Orcon, Itho Daalderop, Zehnder, Honeywell, Kopp, FS20, Eldat Connectivity Wi-Fi, USB-C & MQTT Wi-Fi, USB-C & MQTT Signal range Wide range, commonly used consumer band High wall penetration, less susceptible to interference What makes the EMC version unique? Built-in Extended Motor Control (EMC): The RFX-433EMC includes advanced protocol support for special motors such as Cherubini and Ozroll, including bidirectional feedback (DD27xx) for roller blinds and screens. Transmit and receive (Transceiver): This module not only listens to sensors (such as temperature, wind, and rain gauges) but can also send active commands itself to control motors, roller shutters, and switches. Built-in Wi-Fi & MQTT Auto Discovery: No mandatory USB cable directly into your server. Thanks to Wi-Fi, you can place the transceiver in the most central spot in your home for optimal range. Via MQTT, learned devices automatically appear as entities in Home Assistant. 100% Local & Privacy-first: No cloud, no external servers, and no subscriptions. All communication remains local within your own network. European Compatibility Guide: What works and what doesn't at 433 MHz?The 433 MHz frequency is used by hundreds of brands. Below is the exact overview of tested brands and protocols supported by the RFX-433EMC:1. Awnings, Roller Shutters & Window Coverings Somfy RTS & Simu (433.42 MHz): ✅ Yes, works perfectly. Suitable for Somfy RTS and Simu motors for articulated awnings, roller shutters, and garage doors.❌ Note: Somfy io-homecontrol (868 MHz) uses a closed, encrypted protocol and does not work on universal transceivers. Cherubini & Ozroll: ✅ Yes, 100% supported via Extended Motor Control. Specifically supported on RFXCOM's EMC platform for precise control of screens and roller shutters. Brel, Dooya & MotionBlinds (Coulisse): ✅ Yes, works perfectly. Supports both traditional RF motors and bidirectional motors (DD27xx protocol) for exact position feedback in Home Assistant.❌ Note: The newer Eve MotionBlinds work via Bluetooth / Thread (2.4 GHz) and are not compatible. A-OK, TUBE & Gaviota Elite: ✅ Yes. Commonly used OEM tubular motors for awnings and screens are directly supported. Luxaflex (PowerView): ❌ No. Modern Luxaflex PowerView works via 2.4 GHz or Bluetooth/Thread and requires the official Luxaflex Hub. (Older Luxaflex systems with a Somfy RTS motor do work on the RFX-433EMC). 2. Switches, Dimmers & Smart Plugs KlikAanKlikUit (KaKu) / Trust / Nexa: ✅ Yes, 100% support. Supports both the older ARC protocol (with rotary dials) and the modern AC protocol with automatic code learning. DiO Home / Chacon: ✅ Yes. Popular switching modules and smart plugs from Belgium and France work directly plug-and-play. X10 & Intertechno: ✅ Yes. Full support for wireless X10 RF signals and Intertechno switching equipment. ELRO, HomeEasy & Flamingo: ✅ Yes. Affordable plug sets and wireless switches from DIY stores can be easily controlled. 3. Weather Stations & Environmental Sensors (Reception) Oregon Scientific: ✅ Yes. All known V1, V2, and V3 protocols of Oregon temperature, humidity, wind, and rain sensors are received. La Crosse Technology: ✅ Yes. Commonly used 433 MHz La Crosse sensors are automatically read out. TFA Dostmann & Cresta: ✅ Yes. Popular European weather sensors at 433.92 MHz transmit their data directly to your smart home. Ecowitt & Sonoff Plant Sensors: ❌ No. European Ecowitt sensors work at 868 MHz (see our RFX-868). Sonoff plant and soil sensors communicate via Zigbee or Bluetooth. 4. Garden, Patio & Outdoor LivingSupported outdoor applications include: Outdoor Sockets & Lighting: Switch garden lighting and pond pumps from KlikAanKlikUit (Trust Outdoor), Smartwares, and DiO Home. Patio Awnings & Heaters: Control electric
