vrmlogger.py high CPU load and VRM connection dies when String instead of number is sent to e.g. temperature node #6

Closed mhcore-m closed 1 month ago

If a string value eg "60.5" instead of float 60.5 is written to a node e.g. "W/"+portal_id+"/temperature/"+device_id+"/Temperature" the connection to VRM Portal breaks and the local running vrmlogger.py causes a very high CPU load.

The strange behavior is, that the local GX display shows the, in that case, string temperature value correct as a number.

When you say the connection to the VRM portal breaks, do you mean the MQTT/real-time connection, or vrmlogger (which logs data for historical graphs)?

So far I have not been able to reproduce it. I tried setting the actual temperature path but also other float types. You're setting a temperature reading BTW. Is that intentional?

Do you have the log output from /var/log/flashmq/current and /var/log/vrmlogger/current from the time of the event?

Additionally, if you used command-line tools to issue the MQTT commands, those are welcome too, with their arguments.

And what version of VenusOS are you using?

I'm closing this for now because of lack of reproduction ability or information, but you can reopen it once you have more information.
