Hello all, just bought a Nest 3rd Gen and hope to fit it tonight. I'll eventually run a cable from the heat link but just going to power it from the usb plug for the moment. My question is, my current wireless stat is next to the stairs which come down into the middle of the living room. House is mid 90s style open plan. Just wondering if this is an ideal place for it as it will have a lot of heat running past it as it escapes upstairs. These are internal walls and not exterior as advised against in the Nest literature. The previous wired stat was next to the living room door which led to the porch. Any advice gratefully received.
