mySensors - Good for bin?

Last week, I decided to switch from Jeedom to HA, who looked very great and powerfull.
But, now, I’m not sure to have done the good choice :
I have about 20 mysensors’s node, who send their values to HA.
I even can switch my relays with HA.

But I need to send infos from HA to my nodes (for LCD displaying, etc.)
I first tried with text messages, but no luck : the notify.mysensors seems to be abandonned :

The mysensors HA documentation seems to need an update.
So, instead of V_TEXT, I tried to use V_TEMP to send a virtual temp from HA to my nodes : no way to get something from HA.
Does someone have a workaround ?
