Hot water is cozy — but did you know it can account for up to 20% of your electricity use in winter? Now there’s a smart way to take back control: by connecting your electric water heater to Hilo.
Doing so lets you automate your participation in energy-saving challenges, helping ease demand on the grid during peak periods — and saving you money along the way.
You’ve got two easy ways to do it:
- Get the Hilo smart water heater controller (available free of charge*)
- Or pair your Calypso water heater controller with the Hilo app
Here’s why it’s worth making the switch:
1. Maximize your rewards
Automate your water heater’s participation in challenges and earn up to $45** more per season (depending on the size of your unit). It’s an easy way to get more out of Hilo.
2. Keep your comfort
No cold showers here. The controller lets you use a moderate amount of hot water during challenges — roughly 25 minutes’ worth with a 60-gallon tank*** — without impacting your rewards.
3. Optimize your energy use
With the Hilo app, you can monitor your electricity use in real time — including how much your water heater is using. More visibility = smarter energy choices = potential savings.
Already have a Sinopé Calypso controller?
Good news! Both the Zigbee and Wi-Fi models of Sinopé’s Calypso water heater controller are now compatible with Hilo. Just link yours to the Hilo app to start participating in challenges automatically — and get a $105 cash bonus**** just for connecting.
Want to save even more? Pair your water heater controller with Hilo’s other smart energy solutions — like thermostats or EV chargers — for even greater impact.
