Koeed B2B Tool — Gree WiFi Connection Diagnostic Assistant

This interactive troubleshooting assistant helps HVAC engineers diagnose common MC31-00/C2 WiFi pairing and cloud connectivity issues.

Troubleshooting & FAQ

Why does the MC31-00/C2 fail during WiFi pairing?

Most field deployment issues are related to 2.4GHz network compatibility, router security settings, or incorrect AP pairing sequence.

Can this module operate on 5GHz WiFi networks?

Typical Gree HVAC WiFi modules are designed for 2.4GHz infrastructure. Mixed or unified SSID environments may cause onboarding failures.

Why does setup freeze at 49% or 69%?

This commonly indicates cloud registration interruption, unstable AP communication, or incompatible router encryption configuration. Field reports frequently reference this behavior during Gree+ provisioning. :contentReference[oaicite:2]{index=2}

What is the default hotspot password during pairing?

Multiple field reports indicate the temporary AP password is commonly 12345678. :contentReference[oaicite:3]{index=3}

Can the module support remote control outside the local network?

Yes. Proper cloud registration allows remote operation through the Gree+ platform over internet connectivity.

What causes intermittent offline status?

Possible causes include unstable DNS routing, regional cloud server issues, router isolation settings, or outdated firmware synchronization.
