I picked up the work by https://github.com/crottolo/ and added a node to execute methods/buttons via calling the execute_kw function. This got necessary to fire actions in Odoo like confirming production orders etc.

msg.filters = [["|",["phone","ilike", msg.payload],["mobile","=", msg.payload]]];
msg.filters = [[["bom_id","=", msg.bom_id]]];
msg.filters = [[["id","=", 23]]];

msg.offset = 0;
msg.limit = 0;

msg.fields = (['name', 'fiscalcode']);
