**Update V2: Changed Bottom Interface and Main Housing to also fit eBZ DD3.** This Gadget reads out your smartmeter and can send the data via wifi. Hint: Flash before mount! :-) tested electricity meter: * DTZ541 * eBZ DD3 * eHZ-EDL MT681-D4A52-K0p To Build it you need: * Wemos D1 Mini * [Volkszaehler-Board](https://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf-ttl-ausgang) * neodym-magnet-ring 27x16x5,5 See pictures how to mount everything. This design is a remix of ["ESPHome Holley DTZ541 Three-Phase Meter Interface"](https://www.printables.com/de/model/353319) from LayerCake that i found on printables.com. This was changed: * rebuild the complet desgin to make wemos D1 Mini fit in it * expand all tolerance to make buildable with my bad calibrated printer * added wifi symbol Print the bottom part in black to let the LED's work better. For the Software i used tasmota by follow [this instruction](https://homeitems.de/smartmeter-mit-tasmota-auslesen) (german). If you need it, let [google translate](https://homeitems-de.translate.goog/smartmeter-mit-tasmota-auslesen/?_x_tr_sl=auto&_x_tr_tl=de&_x_tr_hl=de&_x_tr_pto=wapp) the instruction. It took a while to compile the tasmota firmware with enabled scritpting. Thats why i uploaded it here to save you some time. <b>I'm really looking forward to see you makes. :-)</b> If you like my design, feel free to support my by sending me a tip via PayPal.
