Support & contact

Open our documentation and select your product and hardware version. You will find installation steps, connections, configuration and known points of attention in one place.

Check the product label, your order details or the product information reported by the device. If you are unsure, include a product photo and your order number in a support ticket.

First check the compatibility list on the product page and in the documentation. If your model is not listed, send the brand, model number and clear photos through the support portal.

Most products are designed for Home Assistant and ESPHome. Supported devices can also be used with the SmartHomeShop app and cloud, which are still under development.

Yes. With local firmware, Home Assistant and device data stay within your own network. Choose the cloud variant only when you also want to connect the device to the SmartHomeShop app.

Connect the device, join it to your network and add the discovered ESPHome integration. Our own Home Assistant integration adds extra features and ready-made cards for supported products.

Check that Home Assistant and the device can reach the same network. VLAN settings, blocked mDNS or firewall rules can prevent discovery; you can also add the IP address manually.

Use the installer on the firmware page or the temporary configuration network provided by the device. Follow the product manual for the steps that match your hardware version.

Go to the firmware page and select your product, hardware version, local or cloud, and then Wi-Fi or Ethernet. Verify every selection before starting the installation.

Always choose the variant that matches your exact hardware version and network connection. Local is the default for Home Assistant; cloud adds the SmartHomeShop app connection.

No, updates are not installed without your approval. You can install a new release through ESPHome or use our firmware page again when an update is available.

Refresh the page, check your internet connection and try a current supported desktop browser without blocking extensions or a VPN. If it persists, send the selected product variant and a screenshot.

Check the power supply, cables, network connection and status LEDs, then restart the device once. Note the LED behaviour and include any ESPHome log lines in a support ticket.

This depends on the product and installation. The P1SplitterKit always needs external power with DSMR v2, v3 and v4; USB-C may also be required or more reliable with DSMR v5, especially with several connected devices.

The product page and cart show the current status. A back-order includes its expected shipping date; an order is normally shipped when all products are available.

Checkout calculates tax based on the delivery country and VAT status. Arrange any VAT exemption through the support portal before ordering so the details can be verified correctly.

Invoices and order details are available through the support portal. Use the same email address as your order when you need help retrieving an invoice.

Open a ticket through the support portal before shipping anything. Include your order number and the return reason or fault; you will then receive the correct return instructions.

Our products include a standard two-year warranty. Keep your proof of purchase and report a fault through the support portal first so we can investigate and provide an appropriate solution.

Use Discord for general questions, ideas and community help. Open a ticket for orders, invoices, returns, warranty or situations where you share personal details, photos or log files.
