This thread is going to be very contextual. I'm currently sailing on a small sailboat, and hence the items will be quite different than what would be useful ashore:

* Wacaco Nanopresso - manual espresso pump. Great coffee anywhere off-the-grid. We also have their grinder but that's not listed as it is above the $100 threshold

* Klean Kanteen insulated water bottle - fill up from watermaker water, stays nice and cool

* Seeed T1000-e: waterproof Meshtastic radio that allows me to communicate with our boat and crew also when out of cell coverage

* Shelly 1: WiFi/Thread relay that makes it easy to automate navigation lights and other circuits

* Ruuvi Tag: waterproof battery-powered Bluetooth temperature/humidity/pressure sensor. Battery lasts arpund two years. We have a few of these around the boat, including one in the fridge

I should get one of those Ruuvi Tag...I use a similar cheap Xiaomi sensor currently but the battery doesn't last anywhere as long (probably because it has an LCD screen and isn't made to broadcast via BLE continuously).
