Thermostat cannot be added to Bosch smart home ecosystem or third‑party integrations (e.g., voice assistants) fail.

Safety: No electrical work is needed.

• Check compatibility: Verify that your specific Bosch smart thermostat model supports the desired integration (e.g., Alexa, Google Assistant).
• Update everything: Ensure the Bosch app, thermostat firmware, and third‑party apps are all up to date.
• Same network: Confirm that your phone, integration hub (if any), and thermostat are on the same local network during initial pairing.
• Correct region: Some integrations are region‑limited. Ensure your Bosch account region matches the integration’s supported regions.
• Re‑link services: Remove and re‑add the Bosch skill/service in the third‑party app, then follow the linking instructions carefully.
