opencca-hotspot

This module creates a Wi-Fi hotspot to communicate with a smart power plug over HTTP. It is used in the opencca development workflow to power-cycle the board during firmware flashing.

Note: If your smart plug is already reachable via an existing Wi-Fi access point, this module is not needed.

Getting Started

1. Configure Environment

Copy and edit the environment file:

cp ./.env.template .env
emacs .env

2. Install as Systemd Service

Install and enable the service to run at system startup:

sudo make install

See Makefile for more information

Troubleshooting

Connecitivity Issues (Raspberry Pi)

If the hotspot drops or becomes unstable, disable Wi-Fi power saving:

echo "options cfg80211 ieee80211_default_ps=0" | sudo tee /etc/modprobe.d/disable_wifi_powersave.conf
