So I have an outdoor speaker system that feeds into a sonos system inside the house. I would like to have a simple remote control outside where I can mute or skip a song. The problem seems to be the distance and battery of most remotes. It needs to be durable enough to work in the daytime and be easy to use so others can use it. It needs to be weatherproof, waterproof, heatproof for the hot tub and have a good battery life (maybe solar with lithium battery). Does anyone have a recommendations for a weatherproof remote? I have phone apps, but the problem is the battery goes down quick. It would probably have to have a wifi or bluetooth connection, since IR wont work in the daytime. Thanks for your ideas.
