Glad to hear it’s working, it was my error, what I thought was a reset button is just a “RasPi Shutdown” button. When I checked the schematic it isn’t connected to the reset line.
The only way to detect new sensors is to either
- Power cycle the whole emonPi (as you have now done). This must be done carefully, the OS is no longer Read-only, so whilst “pulling the plug” was never a good idea, the filesystem is no longer protected as much as it used to be. You must power down the emonPi using the “RasPi shutdown” button or the “Shutdown emonPi” button in emoncms (not the reboot button) and then remove and refit the power connector. OR
- SSH in and install a small script to reset the emonpi add-on board. (See How to emonhub full reset the emonpi? - #2 by pb66) a request has been made to include a button on the admin page of emoncms (see remote reset rfm2pi and emonpi addon boards · Issue #1166 · emoncms/emoncms · GitHub)
My bad, the small reset button on the emonpi doesn’t reset the emonpi add-on board as I suggested.
