I’m not a plumbing expert and don’t know your pump brand, but most recirculating pumps I’ve seen are at, or near, the lowest part of the household piping, to reduce wear from pumping air, and to be accessible for maintenance. I would not want an electronic motorized machine that pumps water above the ceiling being roasted all summer.
No doubt it was a hassle for you to install the pump and outlet in the attic, but are you sure this was the best long-term solution?
I recommend running a new cable into the attic, with the Zigbee/WiFi relay device in the utility room, garage, or basement, wired in parallel to a manual override switch.
Another option is to disable the recirculation pump in the attic, and install another one (or the same one relocated) where it is more accessible. I have a Grundfos pump next to the hot water heater in the garage, and the pump is plugged into a battery-backed timer.
One option is a Bluetooth beacon along with ESPresence, assuming you’re using Home Assistant.
There are 16 on/off/toggle timers you can configure by default, from the “Configuration->Configure Timer” screen. There is no randomizing ability, but for me this has not been important; no one will be staking out your place over several days recording your light actions. The timer actions can be relative to sunset, so they will vary slowly from day to day. Just remember to check the “Enable Timers” box at the top.
