Smart plugs on stream: a donation turns the light on

Everything it does with a plug, and this is the whole list

It switches a relay and reports whether the plug actually switched. Everything around that — which event, which plug, for how long — is set once and left alone.

• Turn on for a set number of seconds. The countdown runs inside the plug itself, so it goes off even if the app closes or the Wi-Fi drops.
• Turn on and leave it on, with a later step switching it off: a second donation during the wait then extends the light instead of restarting the countdown — nothing caps how far that goes, so keep the wait short.
• Turn off — from a scenario, or by hand on the module page.
• A ceiling per plug on commands that name a duration: sixty seconds until you change it, and a scenario asking for more is trimmed down to it rather than refused. Switching on without a duration is not covered by it — there the scenario decides when the light goes off.
• A pause between switch-ons, so a run of donations does not turn the lamp into a strobe — there is none until you set the seconds yourself.
• A “Test” button on every plug: it clicks and turns itself off three seconds later, without waiting for a viewer.
• As many plugs as you have — each with its own name, ceiling and pause.

What flips the switch while you play

The plug itself is deaf to the stream. The rule lives in Scenarios, and any trigger there can end with a plug switching on.

• A channel points reward the viewer bought.
• A donation — any of them, from an amount and up, exactly that amount, or between two.
• A new follower, a subscription, gifted subs, a raid, bits.
• The stream going live, and the stream ending.
• A button on your control panel, pressed by you mid-game.
• A phrase you say out loud — the recognition happens on your own machine.
• A whole chain, not just the plug: turn on, wait, turn off, with a sound or an OBS scene alongside.

What it is not

It is deliberately narrow, and the edges are worth knowing before you buy a plug for this.

• Not the Shelly cloud: the plug and the computer sit on the same network, and away from home there is nothing to press.
• Not a dimmer: relays only. A lamp goes on and off — no brightness, no colour.
• Not a hub for the whole house: Shelly plugs and relays, not every brand in the room.
• It knows nothing about money or viewers. The plug is told “on for ten seconds” and never learns who paid — and that split is what lets one plug serve several rules without any of them knowing about the others.

No cloud, no account

Most smart home integrations route a button press through a manufacturer’s server on another continent. This one talks to the device on your own network.

• The command goes straight to the plug by its address in the home network.
• Nothing to register and nothing to stay logged in to; with the internet down the plug still takes the command — the viewer event that fires it, of course, does not arrive.
• The delay is what a local network gives you, not what a round trip across the world does.
• The generation is worked out during the search: the plug answers a status request without a password and says what it is. First generation — Shelly Plug S, Shelly 1, Shelly 2.5 and their relatives; second and third — Shelly Plus Plug S, Plug S Gen3, Plus 1.
• A command counts as done only once the plug has been read back and confirms it switched. A lost packet is sent again, and the next command cancels the retries of the one before it.

Where you see that it worked

Every twenty seconds each plug is asked how it is doing, and the answer sits on the module page.

• In the list: responding or not, on or off, and the watts it is drawing right now.
• In the log: done, trimmed to the ceiling, ignored by the pause, overtaken by the next command, or a plug that never answered.
• Addresses are blurred on screen and open on a click, so a screenshot or the stream itself does not hand out the map of your home network.

What it is made of

Each part is a separate module: you install only the ones you need, and any of them can be removed without breaking the rest.

Getting started

1. Put the Shelly plug on the same network as your computer — the same router, not a guest network.
2. In Devices → Shelly press “Scan network”, or add the plug by its address.
3. Press “Test” on the plug’s card: it should click and turn itself off three seconds later.
4. Open Scenarios and add the “Smart Plug” action to a scenario — on a donation, on a reward, on a raid.

Only plug in things that are safe to switch on remotely while you are not looking at them. The app will do exactly what a viewer paid for, including at four in the morning.
