In order to activate autoconso on my Vitotronic 200 I'm considering to buy a smartmeter 7506157 (initially sold by viessmann and now proposed by his owner as "second hand").  This item has not the viessmann logo but the reference Saia ALE3D5FD10C3A00 which seems to be a "Unidirectionnal" meter.  Is it the one I need to feed my Vitotronic PAC with the informations needed for running the mode "PV autoconso" ?
