BW-SHP15 _TZ3000_mraovvmm suddenly stopped measuring

After about 6 monthes of good services, one of my BW-SHP15 plug stopped measuring power and consumption. The consumption counter is not increasing anymore, power and voltage are always 0 even though the plug correctly delivers power to the load (I’ve been using it to charge an hybrid car (2000+ W under load)). I tried to unpair, then pair again with no effect. Could this be a hardware issue ?
