Question: Can you recommend a smart home device that lets me control my air conditioner remotely and monitors air quality?

If you're in the market for a smart home device that lets you control your air conditioner from afar and monitor air quality, Sensibo Smart Home Climate Control is a great option. Sensibo makes a range of smart HVAC and indoor air quality monitoring products that can convert an ordinary air conditioner or heat pump into a smart device. With features like smart scheduling, voice control, remote access and air quality monitoring, the devices can cut energy bills by up to 40%. They work with many air conditioners and heat pumps, are compact and can be integrated with many smart home systems.

Another option worth considering is Tempest, which offers detailed, real-time weather data and forecasts to help you make more intelligent decisions. Although it's focused on weather data, Tempest offers a Home Weather Station that can monitor weather conditions in your home and integrate with popular smart home services like Google Home and Amazon Alexa. That can be useful in conjunction with air quality monitoring, since weather data can be relevant to air quality.

For a more general-purpose smart home option, take a look at Ayla Networks. Ayla offers an all-purpose IoT platform that supports a wide range of smart devices, including sensors and cameras. It doesn't specifically support air conditioning, but its modular design and broad device support make it a good option for more general-purpose smart home setup.

Last, Sense is a home energy monitoring system that uses AI to infer in-home activity and monitor energy usage in real time. It doesn't help with air conditioning, but it can help you understand your energy usage better. The system integrates with many connected devices and IoT-enabled meters to give you a better understanding of what's going on in your home.
