Troubleshooting Item: Wi-Fi

Wi-Fi Connection Diagnosis

Resolving local network connection, signal issues, and pairing failures with the SunHopper^®-D unit.

Introduction

Wi-Fi connectivity is used for smart weather scheduling using the SunHopper^® Algorithm (if enabled), uploading real-time performance data, and tracking energy savings directly to the GreenPWR cloud.

If your device is displaying a network disconnect warning or appears offline in your phone app, it is likely due to signal attenuation, router security configurations, or band mismatch.

Troubleshooting Steps

Network Selection & Signal

1 Verify 2.4 GHz band availability: The unit requires a 2.4 GHz Wi-Fi connection and does not support 5 GHz-only bands. If using a dual-band router with a single shared SSID (band steering), verify the 2.4 GHz radio is active.

2 Check signal strength (RSSI): Ensure signal strength at the installation site is -70 dBm or better (e.g., -60 dBm is strong, -80 dBm is weak).

3 Optimize range: If the unit is installed far from the router or separated by thick walls/concrete, install a standard 2.4 GHz Wi-Fi range extender nearby.

Router & Security Settings

1 Disable MAC address filtering: Ensure the router’s access control list (ACL) or MAC filtering allows new client connections, or add the unit’s MAC address to the whitelist.

2 Check security protocol: Use standard WPA2-Personal, WPA3-Personal, or WPA2/WPA3 mixed mode. Enterprise (802.1X / RADIUS) and captive portal networks (requiring web page login) are not supported.

3 Power-cycle the router: If settings were changed, restart the router to flush stale DHCP leases and resolve potential IP conflicts before re-attempting provisioning.
