Hi @wayneslc, good afternoon! Thank you for your recent purchase of an Iro
Great idea! This should be a simple retrofit. Just remember to use waterproof wire nuts for the splices.
Yep, not a problem. Any of the rain sensors listed on our rain sensor support article are compatible with the Iro. If you're at Home Depot for the wire nuts, they usually have the Orbit Wireless Rain Sensor in stock.
Great question. I believe integrating with Control4 is a great idea if you're looking to complete your home automation ecosystem. For more information on the integration, please see our Control4 support article.
Hope this helps!
