I’ve got a closed loop hot water system and is 200 foot run, with a new Grundfos Alpha pump. The old Grundfos had a remote, but inevitably I forgot to shut it off. The Alpha has the same technology as the Nest products in that it eventually figures out your usage patterns and adapts. I LOVE this product. I use the normal/hi-temp scrub, and sand rinse cycle on the dishwasher, and the pump comes really close to anticipating fill times. It took 2 weeks of “learning “but it works. Glad I have a smart home, cuz I’m not smart. I travel a fair bit and it’s nice to look inside/outside the house, control the lights, temperature etc from my tablet.
