Which modules from ABB use this? I've looked at their site but only found video-over IP stuff... |
@nagyrobi Look in the category "ABB-Welcome" (the one without IP) here or "Busch-Welcome" here They are quite common in Europe. More info: https://developer.nuki.io/t/abb-or-busch-welcome-series/3026 |
How do these (non-IP) transmit audio/video to each other? Also RF? Scrolled through the manual, only need a wire pair for power? |
No, there's no RF. Everything is sent over the two wires. Not sure about the audio but the video signal is analog. They are using an ADV7180 for decoding. As you can imagine, the video quality is not the best and they only let you save 480x360 jpegs, no videos. Can't recommend haha |
What is this component for, if that's the case? |
@nagyrobi For sending and receiving messages on that two wire bus. You need a custom circuit: esphome/esphome#4689 |
Oops... That needs a very clear note in the doc. |
Do you have any info about how's audio transmitted over the wires? Since we're starting to support mic/line input on ESPHome, this could be a nice extension to a future smart intercom through HA... |
No, sorry. I would need to do some more reverse engineering of the PCB and it would certainly require extra hardware. |
