Eight Shelly Plug S MTR Gen3 plugs measure the consumption of every desk in the coworking space, and a Shelly Power Strip 4 Gen4 smart extension lead handles the shared areas such as the kitchen or the printing corner. In the Shelly app you see what each desk uses, switch everything off on a schedule and find the appliances left on.
What it does
- Each Shelly Plug S MTR Gen3 measures the power and energy of the desk it feeds: monitor, laptop charger, lamp.
- The app shows the kWh per desk by day and by month, useful for splitting the costs or for a pay-as-you-use plan.
- The Shelly Power Strip 4 Gen4 switches the sockets in the shared areas, for a kettle, a coffee machine or a printer.
- At the end of the day every workstation and shared area switches off on a timer, apart from whatever you choose to leave on.
- An alert flags the workstations that are drawing power overnight or on closing days.

Before you order
Do you need a hub?
No. The plugs and the extension lead connect straight to the coworking Wi-Fi. You need good Wi-Fi coverage at every desk and an internet connection to use the app remotely.
Does it work with Alexa, Google and Apple?
Yes. The Plug S MTR Gen3 sockets are Matter compatible and add to Apple Home, Alexa and Google Home with a Matter controller; on top of that there are the Shelly skill for Alexa and the Shelly integration for Google Home. Every device also works in Home Assistant.
Can I split the consumption between the coworkers?
The app shows the kWh of each socket by day and by month: a solid basis for splitting the costs or offering a pay-as-you-use plan. It is not a fiscal meter: for invoicing, what counts is the agreement you make with your customers.
Do you need an electrician?
No. The plugs and the extension lead go into the existing sockets, with nothing touched on the electrical installation. They can be moved when you rearrange the desks: in the app you just rename them with the new desk number.
What happens if there is no internet?
The schedules are saved in the devices and carry on working, and the sockets carry on metering. Without internet you cannot see the consumption remotely and cannot use voice control until the connection is back.
Can I add desks?
Yes, one more Shelly socket per new workstation is all it takes: it appears in the same app, with its own consumption. For large spaces consider a meter in the board as well: get in touch through the contact page for the build.
Are there batteries?
No. The plugs and the extension lead are mains-powered and use no batteries. After a power cut they reconnect to the Wi-Fi on their own and pick up the schedules you set, with nothing to do.
What if a product is out of stock on Amazon?
It happens, above all with multipacks. Get in touch through the contact page quoting the kit code and the item that is missing: we will point you to an alternative that works with the rest of the set, so you can finish the order without changing the other parts.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon when you buy. The kit itself is our own work: we picked parts that work together, plus the accessories needed to fit them.
