Frequently Asked Questions
Kasa smart plug offline every morning — why?
Daily offline events usually indicate the router assigns a new IP address to the plug via DHCP and the Kasa app briefly shows it as offline during reconnection. Assign a static IP or DHCP reservation to the Kasa plug in your router settings to prevent this.
Kasa plug shows offline but the light on the plug is solid green — cause?
A solid green light means the plug is powered but not connected to the Kasa cloud. This can happen when internet access is lost. Check whether the router has an active internet connection — the plug may be on the local network but unable to reach Kasa servers.
Kasa smart plug goes offline after every power cut — what to do?
After a power cut, the Kasa plug should reconnect automatically within 2 minutes of power restoration. If it consistently fails to reconnect after power cuts, the router is still starting up when the plug tries to connect — the plug reconnects faster than the router. This usually resolves itself; no action needed.
