- Learning algorithms that adjust temperatures based on usage
- Integration with smart home platforms (e.g., Google Home, Amazon Alexa)

According to Mass Save, residents in Massachusetts may also be eligible for rebates and incentives when choosing approved models.
These savings are even more impactful in towns like Randolph, where a typical home heating bill can spike sharply in winter months.
