Remote headless Kodi for music

Somewhat Kodi related. My pool house is 300 ft from my house. I have a pair of speaker connected to a RPi3 with a wireless connection. I would like to sit at the pool and and remotely control the music. I have an iPad and can use Chorus but the connection is flaky. Kodi remote on my Android phone is worthless. I there a better option to make this work?
