Echelon/NES Smart Meters – dabbling the hardware v1.10 and v2.00

Our software fix for the (fake?) MAX3232 hardware issue seems to solve the issue completely. It is still a rough implementation in the software (using delays), so we’ll have to improve on that later on… It is probably not that big of an issue – because when a MAX3232 starts to behave, it seems it …

Echelon/NES Smart Meters – the software solution to a hardware issue

Well, we warned you that software guys like us tend to come up with software solutions – even for hardware problems. As expected, no electronic engineers reached out to us with a solution for our (probably fake) MAX3232 issues, so we had to come up with a solution ourselves… That is off cause ok – …

(Guest writer) Echelon/NES Smart Meters – NES/ECHELON electrical meter connect to MQTT (Home Assistant) via IR

This is another bonus entry on our blog in the Echelon/NES Smart Meters series. As we have mentioned before, it is sometimes hard to find time besides our regular jobs to dabble with this project. We have had a lot of interest in using the IR (Infrared) port on the Echelon/NES Smart Meters, and there …


We are friends dabbling with electronics, software and …. stuff, and need a place to document whatever we learn.
