How can I remove a carriage return, add a time stamp and ignore some data from a live MQTT feed

I type mosquitto_sub -d -t +/# from the Ubuntu terminal to access the MQTT stream.

The output is this:

Sending PINGREQ
Received PINGRESP
Sending PINGREQ
Received PINGRESP
Received PUBLISH (d0, q0, r0, m0, 'm/jsyd/TEST/001/d/status', ... (34 bytes))
Sending PINGREQ
Received PINGRESP
Received PUBLISH (d0, q0, r0, m0, 'm/jsyd/TEST/001/d/SVlts', ... (28 bytes))
Sending PINGREQ
Received PINGRESP

To filter I add mosquitto_sub -d -t +/# 2> >(grep PUBLISH) this will only allow lines with PUBLISH in it, hence the ouput is:

How would I be able to eliminate a few of the fields and also add a time stamp everytime I receive something; I 've tried using sed but had no luck. I entered $ mosquitto_sub -d -t +/# 2< <(grep PUBLISH) 2< <(sed "s/^/ date/") , $ mosquitto_sub -d -t +/# 2< <(grep PUBLISH) 2< <(sed "s/^/$date`/")

Q: How can I change my input to the terminal so that the output from the above live feed would be:
