## Configuring no-neutral wifi switch on tasmota firmware

- Sonoff SA-018 equivalent (https://www.aliexpress.us/item/3256804183990170.html)
- Flash tasmota onto the module, use its hotspot to configure it onto the IoT wifi network
- Find its IP address via DHCP clients list, open its web config screen, add this config:
  - MQTT settings, use router as mqtt host
  - Configure via tasmota console:
  - Rule1 on switch1#state do publish cmnd/foobar/SWITCH %value% endon
  - Rule1 1  # to enable this rule
  - SwitchTopic 0    # disable auto broadcast of switch state to topic
  - SwitchMode 1     # mode 1 = follow (0 = off, 1 = on)
  - PowerOnState 4   # the switch module's power output state will default to "ON" after boot, and the switch input won't affect it
- socat bridge from wifi router to mqtt broker
