Besides that, connected HVAC platforms can give the users direct access to the power consumption and carbon dioxide emissions stats; they’ll provide deep insight into what kind of a carbon footprint buildings leave behind.
Here’s a potential scenario of a modern HVAC system contributing to energy usage minimization.

Suppose a client’s connected platform is set to turn on air conditioning at 5 pm – the homeowner usually comes back at 7 pm, and it takes about two hours to achieve the most comfortable temperature conditions. However, one day an urgent meeting occurs, and the tenant can’t make it home till 9 pm. If the data from Google Calendar and Google Maps is incorporated into the HVAC infrastructure, the system will recognize the scheduled meeting, take into account expected traffic conditions, and postpone the devices’ activation till, say, 7.30 in the evening. For people with flexible work schedules, the connected platforms can save them lots of money.
Seeing large organizations throw their hats into the IoT ring has inspired multiple smaller HVAC manufacturers to follow suit. They, too, aim to employ the latest tech to reinvent their business models and go from simply selling and deploying HVAC devices (and fixing the broken appliances) to offering predictive maintenance and other high-level HVAC services around them.

If you happen to be one of the suppliers seeking to harness the power of IoT, you might, following the giants’ lead, start equipping your appliances with more sensors, gathering all the operational data and leveraging the cloud, from a trustworthy provider, to implement analytics functionality. Including connectivity into equipment will help increase its life-span, stay connected with clients and increase their satisfaction by continuously improving the products.

2- Plan out the app development. Some execs assume that remote control of HVAC appliances, from mobile or web apps, is just an add-on feature when, in fact, it should be woven into each stage of the connected product engineering. The app’s capabilities must be thought out in advance and questions such as the following must be addressed at the project’s outset:
Will the users be able to manage through the app’s dashboard several stand-alone HVAC systems at once?
Will the remote, off-site controlling capabilities be limited for security purposes?
What if the internet connection crashes or the device’s battery dies out? Have we an efficient system in place to collect and update local behavior while offline?

3- Ensure Over-The-Air (OTA) updates are easy to implement. This is one of the key advantages associated with the IoT and a distinctive feature of connected devices – their improvement continues after the installation is done.
Make sure you devise a method for adding new features to HVAC tools quickly and that the system can be modified, without undue delays, to suit the client’s preferences. That said, don’t neglect safety measures either: All the state-of-art protection methods must be applied and the security system itself must be updated, via OTA communication, whenever necessary.

4- Do not experiment with hardware. When it comes to networking protocols and connectivity, you shouldn’t take any chances: don’t stuff your equipment with shoddy Wi-Fi chips from some no-name supplier to save a few dollars. You want the wireless connectivity in your HVAC system to have a full networking stack and opting for the premium hardware most leading smartphones are already using is the best way to ensure that. Premium hardware will also help deliver high-level security, prevent insufficient wireless range or lack of compatibility.
