One staff for the whole living room
Stav is a universal remote with a 2.8″ touchscreen. It controls Skjold, the TV, Apple TV and the projector, learns the codes from your old remotes and runs «Watch TV» or «Good night» with one press. It is designed to be built at home.
Stav is designed and checked, but not printed, built or tested on hardware. The 3D model is checked for collisions and wall thickness, and the firmware is validated with esphome config, but not compiled. The main board has not been ordered. Everything below is the plan, and the battery and weight figures are estimates, not measurements. Follow the work in the build guide on GitHub (in Norwegian).
2.8″ touchscreen
IPS, 240 × 320, almost edge to edge. Shows what is playing, apps, inputs, lights and scenes.
Apps and inputs
Open Netflix or NRK TV right from the screen, pin favourites, and switch between HDMI 1–4 and TV.
One press, everything happens
Watch TV, Apple TV, Movie, Music and Good night turn on the TV, switch input, open the app, start Skjold and set the scene.
Learns from the old ones
Point your old remote at the nose and press. NEC, Samsung, Sony, RC5 and LG, 2 × 56 slots.
Every key is an event
Short, long and double presses go to Home Assistant, with a ready-made blueprint for automations.
Stands and charges
Magnetic pogo charging in a 65° dock, with a big clock and what is playing on the screen.
Straight and flat
55 × 202.5 mm and 13.5 mm thin. Soft corners, a chamfer around the edge and straight sides. The top is light and the bottom dark, split by a straight seam.
Gold where your thumb rests
A large Ø 39 mm gold ring with a dark OK in the middle. Above it sit power, the gold Skjold key and menu.
Thin from the side
Low-profile switches on a 1.0 mm board keep it thin: 15.0 mm at the thickest, at the gold ring. It weighs about 105–115 g with the battery (estimated).
Light or dark
Bone White matte PLA with a dark bottom, or a dark top with a light bottom. The symbols are inlaid and printed in a contrasting colour.
Pick a device, and the keys follow
The «Controls» chip at the top shows what the keys act on: living-room TV, Apple TV, Skjold or the projector. At the bottom are four tabs: Start, Device, Home and More. Skjold is controlled with the same API the app uses.
Three tops, the same inside
The key block below the gold ring comes in three layouts. The board and firmware are the same: you print the top and caps for the layout you want, and pick the same one in Home Assistant. No reflashing.
A place to stand
Skjold Dokk holds Stav at 65° and charges it through a magnetic pogo connector. While it stands there, the screen shows a big clock, the date, the charge and what is playing, and it never sleeps. At night the screen dims. The dock has USB-C at the back and a weight pocket in the base, so it stands steady.
Three ways to build it
The enclosure prints on a Creality K2 without supports, the parts come from AliExpress, and the firmware is ESPHome. Pick the electronics that suit you. The parts for the standard version cost about NOK 630.
Weeks, not days
A 1200 mAh LiPo battery, and deep sleep while it lies still. It wakes on a key press, or when you pick it up. This is an estimate, not a measurement.
3–4 months
10 pick-ups a day, 30 seconds each.
About 4 weeks
30 pick-ups a day, 45 seconds each.
About 6 days
2 hours with the screen on every day.
70–90 µA
About 2 mAh a day. The display, touch and IR receiver get no power.
Use any key for anything
The ESPHome integration finds Stav. Every key is sent as the event esphome.skjold_fjernkontroll, in the same shape for all keys, and the blueprint lets you pick an action per key and press type without writing YAML.
event_type: esphome.skjold_fjernkontroll data: knapp: tilbake # key: av, hjem, meny, opp, ned, ok, spill_pause … type: lang # kort | lang | dobbel (short, long, double) enhet: "1" # 0 = TV, 1 = Apple TV, 2 = Skjold, 3 = projector

Why Stav?
«Stav» is Norwegian for staff. A staff is long and slim, and it points. In Norse times the staff was both the walking stick and the wand, the thing you pointed with to make something happen. That is exactly what Stav does: point, press, and the room follows. Short, Norwegian and in the same family as Skjold, Røst and Dokk.
Not for sale yet
Stav is not built yet, and there are none to buy. Leave your name and email, and I will let you know when the first one is built and tested, or if there is a kit.
