Hi! I am trying to reconnect an emonTH v 1.5 (I think) after a long period of time. Batteries were dead for quite long. The led turns on when batteries are inserted and it won’t go off. The sensor appears on inputs but no values are fed (n/a NULL is displayed). I didn’t change the node config (on on for 26). A second TH is working OK.
I just flashed and updated the emonpi and looks like everything is OK.
I was checking the pins to consider getting a USB programmer and then I thought I hadn’t tried the mandatory whacking it against the table, which I did. The LED turned off, I thought it was GAME OVER, but it has been properly working since then (few days ago).
I’m not with you there. You can tell the radio version by removing the cover and looking - there are pictures of all the versions of the radio modules we have used/do use in the ‘Learn’ section. But to find the version of the emonTH itself, that’s on the underside of the p.c.b. and you’ll need to remove it from the case to see. It’s only 4 screws, but they’re small and fiddly.
