Walls, metal objects, and other electronic devices will reduce this range, so performance may vary in typical indoor environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this RF relay receiver with my existing 86-type wall switch panel?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — this receiver is designed to work with standard 86-type wall transmitter panel switches in 1, 2, or 3-gang configurations. It uses universal 433.92MHz learning-code technology, making it compatible with a wide range of RF remote panels.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the RF smart switch relay work with smart home systems like Alexa or Google Home?\u003c\/h4\u003e\n\u003cp\u003eA: This device communicates via RF (radio frequency) at 433MHz and does not include Wi-Fi or Zigbee connectivity. It operates independently via its paired RF remote and does not natively integrate with voice assistants or smart home hubs without an additional RF-to-Wi-Fi bridge.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I install the wireless relay receiver safely?\u003c\/h4\u003e\n\u003cp\u003eA: Always switch off the circuit breaker before starting. Connect the live (fire) wire to the L terminal, neutral to N, mains input to INPUT, and lamp output to OUTPUT. Secure the unit with the included double-sided tape or screws. Restore power only after confirming all connections. It is strongly recommended to have a licensed electrician verify the wiring.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the maximum wireless range of the RF 433MHz smart switch receiver?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"In an open area with no obstructions, the RF 433MHz relay receiver can communicate with its transmitter at distances of 20–100 meters.
