Spapilot: Cut your hot tub energy costs by 80% with smart heating

Hey Product Hunt! I'm Pierre, founder of Zavepower. We built Spapilot because we were frustrated with our own hot tub electricity bills. In Sweden, a typical spa costs EUR 80-100/month to heat — and most of that energy is wasted heating at peak prices when nobody is bathing. Spapilot connects to real-time electricity spot prices and shifts heating to the cheapest hours automatically. The result: same comfort, 40-80% lower costs. No new hot tub needed — it retrofits onto any Balboa or Gecko system in about 15 minutes. We're a small team based in Sweden, currently selling through dealers in Germany, the UK, and the Nordics. Would love to hear your thoughts — especially if you own a spa or work in smart home/IoT. Happy to answer any questions about the tech, the energy savings data, or how spot-price heating works!
