That’s a known issue with firmware 1.0.4. From 1.0.5 we have added capability for the device to re-connect once it detects the connection to router has lost. I need to add some descriptions in the user manual about how to update firmware, but here is a quick walk-through:
1. Download the new firmware from:
https://github.com/OpenGarage/OpenGarage-Firmware/raw/master/Compiled/og_1.0.5.bin
2. Open a browser and type in OG’s IP address. Then click on the ‘Update’ button at the bottom of the homepage.
3. Select the file you just downloaded, and type in device key (if you’ve never changed it, it should be opendoor by default).
4. Wait till the upload to complete. In some rare cases (due to WiFi signal quality) the upload may fail. In that case, just repeat the steps.
