Signal K/MQTT issue - Help!
#1
Hi all,

I've got a bit of a problem and I hope some one might be able to help. It might be a bug or just me.

I'm running Openplotter 1.2.0 alpha, fresh from an updated img.

I am trying to display on Signal K instruments using MQTT data derived from ESP8266 connected temperature sensors.

I can connect a single MQTT topic and SignalK will create instruments and display data successfully (tempA).

I configure this on the MQTT tab of the OpenPlotter control panel.

As soon as I configure my second topic (tempB) the pi's CPU usage goes up to around 70%.

HTOP shows mqyy_d.py up at 130% cpu usage, the Signal K dashboard indicates 100+ deltas/sec.

As soon as I delete either topic everything settles down.

The mosquitto broker accepts the two topics with no problem, I can dedug with mosquitto_client.

(added) P.S. Node RED displays both topics OK so this might be a bug.

Huh Any ideas?
