If you have a sonoff basic module, a simple light blinking .yalm is possible with the tasmota firmware command “Power 3/blink” and “Power 4/blinkoff”. Try this in your configuration.yalm: …using my sonoff #3…
...
- platform: mqtt
name: "flasher"
command_topic: "cmnd/sonoff3/power"
payload_on: "3"
payload_off: "4"
you then get a 1 sec. blinking light function in Home Assistant.
Let me know if I’m pointing the obvious, I’m new … looking for a Hass blink light function
didn’t give simple results…
