1 You must accept the Participant Agreement and commit to 12 months of automation during peak demand events.
2 Remote control through the mobile app is available for all Hilo thermostats and select compatible models. Note that some compatible models can only be controlled remotely through their brand’s app.
* Average potential savings are based on actual consumption by Hilo customers enrolled in Rate Flex D who participated throughout the entire 2025–2026 season. The averages are based on estimated savings observed under a scenario of 84 hours or 21 peak demand events and attributed to each category of connected devices supported by Hilo (data to be validated in summer 2026). Calculations are based on Rate Flex D prices in effect during that season. Potential savings represent the difference between Rate Flex D and Rate D (the base rate), including applicable taxes. Actual savings may vary depending on the combination of connected devices, home or vehicle characteristics (if applicable), energy use or charging habits, peak event participation rate, and weather conditions.
To take part in automation during peak demand events and maximize savings on your electricity bill, use Hilo products or add compatible devices to the app.
Hilo products give you more — unlocking the full range of features in the Hilo app. And since your first installation is free, it’s the perfect time to get all the devices you need to maximize your savings.
