MQTT batterylevel reporting

I've migrated from serial to mqtt. With the serial connection I got the sensors to report the batterylevel, but I can't get it to work with the MQTT GW.
I've seen, that there's a "default" battery reporting line in MySensor.h
void sendBatteryLevel(uint8_t level, bool ack);
But how do I adapt that to mqtt?
Can I just add the line at the end of the default temperature sensor loop?
Because I'm lazy at soldering I only have one battery board so far that actually reports battery level, but for me the battery is coming through as
Or whatever, "92" being the payload. I went into MyMQTT.cpp and changed the pertinent line to
char V_50 PROGMEM = "BATTERY_LEVEL";
So it looks a bit prettier and easier to catch in Python. As for actually using that value with some controller / HA software that is another matter. I myself save it as a "user variable" in Domoticz (since many of the dummy sensors in Domoticz can't have a battery level apparently). That way I can have a long list all in one place of all battery levels and can sort it.
What sort of controller do you use?

I'm using OpenHab as controller.
It worked pretty good when i had a raspberry as a serial gateway reporting to Openhab, but now I've switched to a MQTT gateway on an UNO. That works fine for a few temp sensors, but i'm having serious trouble getting a 8-channel relay node to work. It works for about 1-2 hours then it stops responding Then i have to powercycle it, to get it running again.
Currently the temp sensors report this:
0;0;3;0;9;read: 1-1-0 s=255,c=3,t=0,pt=1,l=1:81
for a battery reading (81%).
