Multimeter setup

Step 2.2: Create the Combined Script for Two TTL Heads​

Combine individual scripts so Tasmota reads data from two meters.

Update the Meter Count​

>M 1
to
>M 2

(The number after M shows how many meters are connected — 2 for two meters.)

Add the Second Meter Line​

You already have this line for the first meter:

+1,3,s,16,9600,MT175,1
TTL Cable Color Codes 
+2,5,s,16,9600,MT175,4
TTL Cable Color Codes

+2 = second meter, 5/4 = IO pins.

Copy Data Lines and Adjust Meter Number​

Copy first meter’s lines, change 1, → 2, and update names (e.g., E_in → E_in2).
