ESP8266 NodeMCU Development Board v2 Case

A small inconspicuous case for a ESP8266 NodeMCU Development Board v2.

Could be used in conjuction with a TTL IR transceiver-head to read Smart-Meters.

For the IR transceiver head you could build your own or just buy a cheap one from eBay, Amazon, etc. (search for "TTL IR Lesekopf").

If you're a customer of Wiener Netze, you can use this firmware to read the customer interface and directly transmit the data to a MQTT broker and for example to Home Assistant.
