Will Metron work with my meter?

Answer one question for an instant verdict — or send a photo and we'll confirm personally within a day.

Look at the front of your electricity meter. Do you see a round metal-and-glass circle, about 2–3 cm wide (the optical port)? Yes, there's a round portUsually on the front face, sometimes marked with a light symbol No / I'm not sureCan't find it, or the meter is very old / electromechanical with a spinning disc

✅ Very likely compatible! That port is exactly what Metron clips onto. It auto-detects IEC 62056-21, DLMS and SML protocols.
