I’m embarrassed to admit I’ve discovered a new, unopened emonTx V3.2 in my storage - complete with enclosure, battery holder and CTs but without the now-hard-to-find RFu board. While it must be 7+ years old, seems a shame to bin it and wondering how best to use it. I’d appreciate some inspiration if anyone has any ideas?
Ideally, I’d like to modify it to work with an esp822 and 2-3 DS18B20 probes to monitor a heat pump system in conjunction with my new emonPi and emonTH’s - but I’m guessing my options are now limited given there’s no microcontroller on this thing?
Is this more trouble than it’s worth at this stage?! Maybe one for my OEM museum now
