EspHome with S0 Interface eltako DSZ15D 3x80

[Sn4k3E4t3r]

Hi together,

i have an NodeMCU ESP8622 and i have no IR Led on my eltako dsz15d. But this Three-phase meter has an "S0+" an "S0-" Interface.

Has somebody the Three-phase meter an read directly the Impulse from the S0 Interface

Hey @Sn4k3E4t3r, did you ever find out? I am in same situation and reluctant to stick in a device in to the presumed S0 ports without being absolutely sure I will not fry myself (or the device)..

Hi @Sn4k3E4t3r @ncvangilse
I have now tested this setup with S0. But i does not work as it is. Did you fint any solution?

I removed your comment from the other thread because it doesn't belong there.

What might work is to desolder the LED from the photodiode PCB and then a wire from the + and - in the S0 ports. But I have absolutely no experience with S0, a friend of mine made a nice project for it: https://github.com/huizebruin/s0tool

The instructions at https://esphome.io/cookbook/power_meter.html (see the note "Some energy meters have an exposed S0 port [...]") work for me using an Eltako DSZ15DE-3x80A attached to an ESP8266 (NodeMCU V2) running ESPHome.
