Bosch EasyControl app cannot find or connect to the thermostat on the local network, even though the thermostat shows as connected to Wi‑Fi.

Safety first: No electrical risk.

• 1. Same network: Ensure your smartphone is connected to the same 2.4/5 GHz SSID as the EasyControl, not to a guest network.
• 2. Disable VPN: Turn off any VPN or private DNS on your phone while pairing or controlling the thermostat locally.
• 3. Router settings: Disable client isolation/AP isolation on the Wi‑Fi network used by the EasyControl.
• 4. Use cloud mode: If local discovery fails but internet is available, control the thermostat via Bosch cloud (remote mode) until local issues are resolved.

Professional help: For complex network setups (VLANs, multiple routers), consult a network specialist.
