Quick start (TL;DR)
- In MySigen → Device tab, copy the serial number after “CMU” (exclude the word “CMU”).
- Go Settings → Network Configure → Next; when the camera opens, tap Enter, paste the copied SN, then Submit.
- Choose “No, I want to connect device to hotspot” → Next → Connect to device when prompted.
- Select your home Wi‑Fi, enter the password, and tap Join. Wait for the tick to turn green, then tap Finished.
Step‑by‑step
1. Grab the CMU serial number in MySigen
- Open MySigen and go to the Device tab.
- Copy the serial number after “CMU” (do not include “CMU”).
2. Start Network Configure
- In the app, go Settings → Network Configure. Scroll down and tap Next.
- When the camera interface opens, tap Enter, paste the copied SN, and tap Submit.
3. Connect to the device hotspot
- Select “No, I want to connect device to hotspot.”
- Tap Next, then confirm “Connect to device?”
4. Join your home Wi‑Fi
- Pick your home Wi‑Fi, enter the password, and tap Join.
- When the tick turns green, tap Finished to complete.
Troubleshooting & tips
- Serial number rejected: Ensure you pasted only the digits/characters after “CMU”—do not include “CMU” itself.
- Can’t connect to device hotspot: Re‑try Network Configure → Next → Enter SN → Submit, then choose the hotspot method again and confirm Connect to device.
- Wi‑Fi won’t join: Re‑enter the password and check signal strength at the inverter; many inverter Wi‑Fi modules work best on 2.4 GHz.
- No success indicator: The process completes when the tick is green and you tap Finished. If the app loops, back out and repeat from Network Configure.
