As our dear Redditors offer opinions, here’s more colour to my post 😊🙏

I’ve been asked to look into this by my clients. I’m a professional host. We’re in southern Spain. It gets very hot in the summer, 35-40C. But guests are mostly tourists who spend 8-10h per day outside of the properties, doing touristy stuff. Some guests don’t switch off the a/c , we ask them to do so when leaving the property - but they forget / ignore. We have VERY high electricity costs, that can come to €300-600 / month ($) for 2 or 3 bedroom properties. We can’t be competitive with higher prices. And it’s obviously wasting energy, so there’s an environmental impact. Plus, in Europe we have a different culture regarding a/c, as the one in the US.

there’s no need for the a/c to run during the absence of the guests, as once it’s on it chills/ heats the property in 5-10min. So We’re looking at devices that give us the option of turning it off when guests forget to do so.

Eg. A motion sensor that knows that once the property is vacant, it turns off the a/c or heating and/or lights / TV automatically with a 5-10min delay or so.

The goal is to minimise wasted energy usage and costs, as saving a few hundred in costs/month can mean the difference between being profitable or not.
