Third-party integrations (Home Assistant, HomeKit, etc.) report an API rate limit or too many requests; the thermostat may appear offline in integrations while working in the Netatmo app.

Note: This is a cloud/integration issue, not a hardware fault.

• Reduce polling frequency: In your third-party system, increase the interval between API calls (e.g., poll every 5–10 minutes instead of every few seconds).
• Disable duplicate integrations: Ensure you do not have multiple instances of the same Netatmo integration running.
• Use official integrations: Prefer official Netatmo integrations where possible, as they respect rate limits.
• Wait for cooldown: Rate limits usually reset after a short period; avoid repeated manual refreshes during this time.

If rate limiting persists even with low polling, consult Netatmo developer documentation or support.
