Merging two table

Hello Everyone, 

I would be glad if you could help me with the following issue :

I have two tables for which I built two Dax measures :

Table 1 :

[Date]                [Robot]            [Total]

01/01/2021       IDN                  300

01/01/2021       ABD                 400

01/01/2021        R3D                500

01/02/2021        F3D                 600

My first Dax measure is the total calculated

Table 2 :

[Date]                [Robot]            [Total]

01/01/2021       BOP 1              300

01/02/2021       BOP 2              400

01/03/2021       BOP 3              500

My second Dax measure is the total calculated

I would then like to consolidate both calcul to add up 1st DAX measure and 2nd DAX measure and calcul it depending on the month (not the day due to cardinality). How can I do it ? should I consider building a third table and merge table 1 and 2 data ?
