Can I install the Staywatt module myself, or do I need an electrician?
The short answer: partially. The fastening of the module to the circuit groups in your meter box — the row of fuses and switches that distribute power throughout your property — you have a certified installer do. But setting it up, which means pairing it with your phone via Bluetooth, entering your tariff per kWh, and creating the QR code that your guest scans, you do yourself.
That division between "skilled work" and "self-management" is not arbitrary. Everything that changes the electrical installation itself — the wiring, the fuses, the connection to the circuit groups — requires someone who knows exactly how your meter box is built and whether it can handle the extra load. Everything that happens after that is software: an app that communicates with a module that is already in place. You can do that yourself, just as you would set up a new wifi router once it is plugged in.
What you do yourself
As soon as the module is in your meter box, you open the Staywatt app on your phone and connect via Bluetooth. In it, you enter the tariff your guest pays per kWh, link the module to the correct object (a holiday home, a chalet, or one specific charging station if you have multiple) and print or stick the QR code on a visible spot. That is the entire process on your end, and it usually takes no more than fifteen minutes.
If you have multiple objects, for example a holiday park with ten chalets and three charging stations, you repeat that for each object. Each object gets its own module, its own QR code, and if desired, its own tariff — a charging station does not have to cost the same as electricity in a chalet.
What the electrician does
The electrician or installer ensures that the module is physically and safely connected: to the correct circuit group, with the correct wiring, and with the certainty that the refrigerator circuit remains separate so that it always has power, even if a guest's balance reaches zero. He also checks whether your meter box can handle the extra load, something that is especially relevant for a charging station.
Work on the meter box is always carried out by a certified professional for safety reasons, regardless of which brand module you choose. This applies not only to Staywatt: any modification to your electrical installation should be done by someone with the right credentials. For the specific rules that apply in your situation, consult an installer or the competent authority in your country.
For the electrician: the technical specifications
The module is connected to a separate circuit group, with its own residual current device — the safety switch that interrupts power in case of a leakage current, for example due to a faulty device. The module measures consumption on that circuit group and switches off the connection as soon as the guest's balance reaches zero, with the exception of the circuit group that is separately marked as the refrigerator circuit. With three phases (three separate power supplies, common in larger properties or charging stations) the module is connected to the phase or phases that belong to the relevant object. The complete technical documentation per hardware type is in the knowledge base.
How much time does it take in practice
The appointment with the installer is usually the longest part, simply because you need to plan a time when someone can come by. The connection itself typically takes no more than an hour per module. You activate it via the app afterwards yourself, at the time you want, without having to schedule anyone again. If you are curious what that concretely means for your situation, an overview of the entire process from order to activation gives a good picture.
Multiple objects or a holiday park
At a holiday park or portal with multiple rental units, the principle does not change: each object gets its own module and its own connection, so also a visit from the installer per object. What you do yourself — set the rate, link the QR code, create the object — simply scales in the app, whether you manage two or two hundred objects. If you are unsure whether your situation requires one module per object or whether a different arrangement would be more logical, then the selection tool with a few short questions will immediately give you an indication.
Do you want to know what it will cost you before you call an installer? The subscription costs per object and the markup per kWh are clearly shown on the pricing page. And if you run into a specific question about your fuse box, your phases or your residual current devices, you will find in the knowledge base with explanations per situation the answer worked out almost always.
