1. Preparing for connection: what to check before starting setup

Before connecting the thermostat Avatto Before connecting to Wi-Fi, you need to ensure that all the conditions for successful setup are met. About 60% of connection issues arise from missing preparatory steps—for example, if the router is operating in an incompatible mode or the network is overloaded with other devices.

Here mandatory checklist before the start:

  • 📶 The Wi-Fi network is working stably.: Check that other devices (smartphone, laptop) are connected to the network without interruptions. If the internet is slow or intermittently disconnects, resolve that issue first.
  • 🔄 The router supports 2.4 GHz: thermostats Avatto do not work on the 5 GHz networkMake sure your router is broadcasting the network at the correct frequency. 2.4 GHz (or enable this mode in the settings).
  • 🔋 The thermostat is charged or connected to power.If the device is battery-powered, replace them with new ones. If it's powered by a power outlet, check that the cable is securely connected.
  • 📱 Application Avatto Home installed: download it from App Store or Google Play (links are official, no third-party sources). The application version must be at least 3.2.0 (valid for 2026).

If your router uses double stripe (2.4 GHz + 5 GHz) with one network name (SSID), we recommend temporarily divide the networks in your router settings. This will simplify connecting the thermostat. For instructions, see the section on router setup.

⚠️ Attention: If you use guest network or network with MAC filtering, thermostat Avatto will not be able to connect. Disable these features during setup or add the thermostat's MAC address to the list of allowed devices (it can be found on the back of the device).
