keyword examples

In this example there are 2 topics, first/topic and second/topic.

1. On first/topic the message consists of two keyword/value pairs, id and temp1. The id value should be ignored. The temp1 value should be converted from Celsius to Farenheit and stored in WeeWX field, extraTemp1. The message would look something like this.

   id=1,temp1=26.7
   

2. On second/topic the message consists of a single keyword/value, outTemp. The outTemp value does not need to be converted and should be stored in WeeWX field, outTemp. The message would look something like this.

       {
       outTemp=80
       }
   

The configuration below accomplishes this. This example leverages MQTTSubscribe's default values. To see a more complete template see, https://github.com/bellrichm/WeeWX-MQTTSubscribe/blob/master/mqttsubscribe.example.conf.
