Confused about which thermostat to pick? Compare six top models—Google Nest, Ecobee, Honeywell, Mysa, Enphase, and Sinopé—with BC Hydro rebates, Peak Saver compatibility, solar integration, and cold-climate performance.
A smart thermostat earns you $75–$150 in BC Hydro rebates, typically saves $15–$20/month on heating, and can optimize Peak Saver rewards worth $3,000+ over 10 years. Payback is 9–12 months after rebates.
Four recommendations based on your priorities: solar integration, DIY installation, warranty, or budget.
Large touchscreen displays real-time solar production and battery status. Built-in AI optimizes heating/cooling based on solar generation + Peak Saver schedules. If you have (or are installing) Enphase microinverters, this is the single best thermostat for optimization.
Includes Power Extender Kit (solves C-wire problems in older homes). Excellent heat pump support tested to -30°C. Integrates with Generac batteries. Strong machine learning algorithm that adapts to your schedule.
Easiest DIY installation (15 minutes). Exceptional 5-year warranty (double industry standard). BC Hydro Peak Saver ready. No learning algorithm, but simple scheduling + geofencing works perfectly for most homes.
Strongest learning algorithm—literally learns your schedule and adjusts automatically. Cleanest UI (expert consensus). Works seamlessly with Google Home. Matter-certified for future compatibility.

How smart thermostats work with BC Hydro's Peak Saver program to earn you money while helping the grid.
BC Hydro program that pays you to shift energy use away from peak demand hours (4–9 PM in winter). Smart thermostats let BC Hydro remotely adjust your temperature by 2–3° during peak events. You get paid for participating.
Enrollment bonus: $50. Additional enrollment incentive: $100. Seasonal rewards: $50–$250/year during winter. Total over 10 years: $1,000–$3,000+ depending on participation.
During peak hours (4–9 PM), BC Hydro sends a signal to your smart thermostat. It lowers your heating setpoint slightly (usually unnoticed). Your battery (if you have one) provides backup heating. You get paid a credit on your power bill.
Confirmed compatible: Mysa, Sinopé, Ecobee (TBD), Nest (TBD). Check with BC Hydro's official list before buying to confirm Peak Saver enrollment is possible for your model.
Peak Saver + smart thermostat + battery = triple win. Your battery discharges during peak hours (4–9 PM) to heat your home while solar charged it during the day. BC Hydro rewards you. You keep your house warm. Grid is helped.
BC Hydro is offering free smart thermostats to some customers with electric baseboard heating (fall 2026). Check eligibility at bchydro.com. If you qualify, free installation + rebates.
How the three work together to maximize your energy optimization and earnings.
Enphase IQ Air: Displays real-time solar production and battery status on thermostat. AI automatically optimizes heating/cooling based on solar forecast and battery charge level. Result: maximize self-consumption, minimize grid purchases.
No native thermostat integration yet, but SolarEdge mySolarEdge app can communicate with compatible smart thermostats. Manually check solar forecast to adjust heating schedules. Works but requires more user involvement.
No direct thermostat integration yet. Eguana is working on Matter integration for future updates. For now: use time-of-use schedules to maximize Peak Saver enrollment and seasonal reward payouts.
Ecobee + Generac: Native integration. Thermostat displays battery status and can optimize heating based on battery charge level. Good solution if you have Generac system.
Most smart thermostats need a C-wire (common wire) for continuous power. If your home was built before 2010, you may not have one. Solutions: (1) Ecobee includes Power Extender Kit (solves the problem), (2) Honeywell T9 includes C-wire adapter, (3) Mysa sells $25 adapter, (4) Nest may work without C-wire depending on your HVAC setup. Check compatibility before buying, or hire a pro for $150–$300 to run a new wire.
Typical savings: $15–$20/month on heating/cooling bills (10–15% reduction). This adds up to $1,800–$2,400 over 10 years. Plus: BC Hydro rebates ($75–$150), Peak Saver rewards ($100–$250/year), and resale value boost. Payback: 9–12 months after rebates.
DIY: Easiest are Mysa (15 min) and Sinopé (20 min). Moderate difficulty: Ecobee (25 min) and Honeywell (25 min). Harder: Nest (30–45 min). Professional installation: $199–$250, plus $129–$150 if they need to run a C-wire. If your home has a C-wire already, DIY is usually safe. If not, hire a pro ($300–$400 total).
Best integration: Enphase IQ Air (if you have Enphase microinverters). Next best: Ecobee + Generac PWRcell. For Eguana battery: Any thermostat with time-of-use scheduling works well. Check with your installer which they recommend for your specific system. Most major brands work well with solar; it's just a matter of how much automation you want.
Mysa stands out with 5-year warranty (double industry standard). Most others (Ecobee, Nest, Honeywell) offer 2–3 years. Why it matters: A thermostat should last 10+ years, so longer warranty = better protection + better resale value for your home. Mysa's warranty is a major advantage if you plan to stay in your home long-term.
Yes. All thermostats in this guide work with heat pumps. Some are better optimized: Ecobee and Honeywell T9 have dedicated heat pump support for better cold-climate performance. Enphase IQ Air is also excellent for heat pumps. Confirm compatibility with your installer before install, especially if you have a cold-climate heat pump (like Mitsubishi or Daikin).
Maybe. BC Hydro is offering free smart thermostats to eligible customers with electric baseboard heating (starting fall 2026). Check BC Hydro's Peak Saver page to see if you qualify. If you do, the thermostat + installation is free, and you get Peak Saver enrollment bonuses too. Worth checking.
Pick your city and get matched with an installer who handles everything—including rebate paperwork. They'll recommend the best thermostat for your system and Peak Saver setup.
