I’ve had my OpenEVSE running for a while now and working successfully, including solar divert.
Recently, I noticed that it is no longer reporting the grid import/export value and instead always displays 0W. The charger should be receiving data via MQTT running on a Pi with Emoncms (with an emonTx). Checking mosquitto.log on the Pi I see some disconnections - though I’m not sure what’s normal:
1642535953: New client connected from 192.168.178.142 as openevse-9c4c (c0, k60, u'emonpi').

In the OpenEVSE web interface, it looks like it has a valid connection:
I am slightly confused as in you description you say you are getting the data from a Pi is this an EmonPi?
if so in the feeds you seem to have you are using emontx1 as the topic
Newer FW versions display the hardware info in the interface. Unfortunately, on your older version, the only way to check for sure is to open up the enclosure and take a look
Updated to 4.1.2 but unfortunately no improvement. When I reset the Wifi on the unit, it seems the timer (that shows time since last data received) goes back to 0. I don’t know if that’s relevant or not.
@glyn.hudson I now have a more pressing issue, level 2 charging is only show 6 or 7A as available charging rates. Level 1 shows 6-12A which I assume is normal.
I have tried rebooting the unit and changing with the car connected/not connected but to no avail.
I know nothing about it, but 120.00 (not 120.13 or something) is highly suspicious to me. It it were an emonTx or emonPi, it would mean it defaulted to the nominal value because it couldn’t detect the actual voltage.
