Ask a Question
  • How does this compare to Irrigstion Caddy? I had the caddy for 10 years in my last house and now want similar for the new house.

    Functionally they are very similar. Wi-Fi enabled, Web browser controlled sprinkler system.

    The main difference this is based on Open Source hardware and software. So there are plenty of integrations and function add ons that people are creating for them.
