selective MQTT keepalive not working

Hello,

I try to send a keepalive message to the MQTT broker to get just 2 topics transferred from DBus to MQTT like so:

mosquitto_pub -h localhost -t 'R/xxxxxxxx/keepalive' -m '["battery/256/Dc/1/Voltage","battery/256/Dc/0/Power"]'

I would expect this to make the venus device publish only the 2 requested topics on MQTT.

It does, however, dump the whole DBus to mqtt, just as if my keepalive message had been sent without payload.

The payload arrives at the broker as expected, which can be seen under R/xxxxxxxxx/keepalive using MQTT explorer.

AIUI flashmq doesn’t support this.

Moving to mods where there is an existing topic.
