TL;DR
This article discusses the design of ultra-low-power smart thermostats using latching solid-state relays (SSRs). The innovative approach allows these HVAC (Heating, Ventilation, and Air Conditioning) controllers to draw power directly from the load, eliminating the need for batteries or a common wire, which simplifies installation and reduces maintenance.
Why This Was Curated
The article provides practical insights into designing low-power smart thermostats, which is relevant for software developers interested in hardware. However, it may lack hands-on tutorials or projects that would enhance its actionability for the audience.
