Radio Shack Fone Flasher

How do I integrate this Fone Flasher with HA? The goal is to receive a text message and turn on the smart bulbs when it flashes.

I tried the luminance sensor on an Aeotc MultiSensor 6, it is hit or miss. Seems flashes are too quick for the sensor. I’m guessing the power monitor may work for this situation. This is why I’m asking around for ideas that I haven’t thought of.

So it just flashes when your phone line rings? I mean you could cobble something together with ESPHome.

Google led me here:

Seems like you could probably go this route and have HA actually know who’s calling you too. No landline so can’t help you further though.

Thanks for sharing the phone modem. This is for a landline phone. Yeah, it flashes when the phone rings, and I unfortunately have no experience with ESPhome.
