You could hack it in after CalHeatMap renders:

// wrap in timeout to let map render
setTimeout(function(){
  var t = d3.selectAll('.subdomain-text') // find all the text blocks
    .text(null); // blank them out
  t.append('tspan')
    .text(function(d){
      return new Date(d.t).getDate(); //append tspan with date
    })
    .attr('x', function(d){
      return d3.select(this.parentNode).attr('x'); // steal parent x value so it stays in place
    });
  t.append('tspan')
    .text(function(d){
      return "€" + d.v; //append tspan with value
    })
    .attr('dy','1.2em')
    .attr('x', function(d){
      return d3.select(this.parentNode).attr('x'); // steal parent x value so it stays in place
    });
}, 100);
