Hi
I wonder if anyone has got a solution on how to read out data via the optical eye (infrared) on a Kamstrup 382Lx7 meter ?
A solution exists, where data is decoded via an Arduino or similar - but I guess the optiomal thing would be to use an ESP8266 (or variant) and send the data to HA via MQTT ? Alternatively, it could be done via a custom component for ESPhome…
I was just wondering if someone already had a working solution - so I could “piggy-back” on that, instead of having to start from (more or less) scratch in order to get something working …
I know the meter has a LED that gives 1000 pulses/kWh - but I find the solution with the optical eye a bit more correct, as the HA-Glow might miss some pulses, where as reading out via the optical eye always will give you the right meter measurements.
