Daniele Verducci 🧉I mounted the <a class="hashtag" href="https://social.ichibi.eu/tag/homeassistant" rel="nofollow noopener noreferrer" target="_blank">#homeassistant</a> <a class="hashtag" href="https://social.ichibi.eu/tag/glow" rel="nofollow noopener noreferrer" target="_blank">#glow</a> temporarily with some tape. I want to test it before building a box for it.<br>I didn't need to mess with the <a class="hashtag" href="https://social.ichibi.eu/tag/photodiode" rel="nofollow noopener noreferrer" target="_blank">#photodiode</a> trimmer, it did match already very well the electric <a class="hashtag" href="https://social.ichibi.eu/tag/counter" rel="nofollow noopener noreferrer" target="_blank">#counter</a> pulses.<br>The <a class="hashtag" href="https://social.ichibi.eu/tag/esp32" rel="nofollow noopener noreferrer" target="_blank">#esp32</a> struggled a lot to get wifi signal, we are very far from the access point, with multiple angled stone wall between. It's a miracle it could connect at all! I'll probably mod the <a class="hashtag" href="https://social.ichibi.eu/tag/mcu" rel="nofollow noopener noreferrer" target="_blank">#mcu</a> to solder an external, bigger <a class="hashtag" href="https://social.ichibi.eu/tag/wifi" rel="nofollow noopener noreferrer" target="_blank">#wifi</a> antenna.
Daniele Verducci 🧉This is it, assembled. The <a class="hashtag" href="https://social.ichibi.eu/tag/rgb" rel="nofollow noopener noreferrer" target="_blank">#rgb</a> led should blink blue in case of network error and red when a pulse is detected from the <a class="hashtag" href="https://social.ichibi.eu/tag/electricity" rel="nofollow noopener noreferrer" target="_blank">#electricity</a> meter. I already added it to <a class="hashtag" href="https://social.ichibi.eu/tag/homeassistant" rel="nofollow noopener noreferrer" target="_blank">#homeassistant</a> (with the <a class="hashtag" href="https://social.ichibi.eu/tag/esphome" rel="nofollow noopener noreferrer" target="_blank">#esphome</a> integration), so now it's just matter of trying it with the counter. I will probably need to adjust the <a class="hashtag" href="https://social.ichibi.eu/tag/photodiode" rel="nofollow noopener noreferrer" target="_blank">#photodiode</a> sensitivity to avoid false positives.
