Utility meter "client information" port

[ddieffen]

In France, my electricity meter has a TIC port that exposes data as a serial text output. By parsing this text, it's possible to read what the utility meter actually measures and what's being billed. This is interesting because it also exposes things like the current "cost period" (e.g. high-price vs. low-price period), the total energy accumulated during high-price and low-price periods, and the maximum allowed power.

I'd like to build a module to read this and integrate it into my EnergyMe-Home device.

In France, to get the data as a serial link, you need to add an optocoupler — the method is described here: https://hallard.me/demystifier-la-teleinfo/

I'm wondering if utility meters in other countries expose something similar, and whether anyone here would be interested in that. I'm going to build the French version first, but if it's feasible to make it compatible with other countries, I might work on that too.

Best regards

Hi! The Netherlands should have something similar. But it is different country by country (commercial products already may exist).

In any case I don't have in mind a clear way to integrate this directly into EnergyMe-Home; rather, I would integrate the latter and your new devices into a unique platform (like Home Assistant) and do comparisons directly there.
