Sensor12 - Expanded documentation for ADS1115 Modes

[phinnay]

Hello all,
I was wondering if there is any documentation on the settings exposed via the Sensor12 option listed here:
https://tasmota.github.io/docs/Commands/#sensors

I understand the concept of single / differential however the documentation shows to enter D0 to D5 for either of the settings, with no indication of what those five states do. The datasheet for ADS1115 lists numerous possibilities but Tasmota doesn't indicate what is mapped to what.

I've searched PR's as well as the normal sources and do not see this info anywhere - if it exists can I get a pointer to where?
Either way, some elaboration in the docs would be great.

Thank you! Tasmota is an amazing project <3

As of today there is no more than PR #15001 from @FransOv

If I remember the discussion the command is Sensor12 mg
Where mg is a combination of mode and gain:

• m = S : single-ended mode, each channel 0, 1, 2, 3 match idependently each input from AIN0 to AIN3
• m = D : differential mode, present only 2 channels where channel 0 is AIN0 - AIN1 and channel 1 in AIN2 - AIN3
• g sets the gain/range with
  • 0 : 6.144V full range
  • 1 : 4.096V full range
  • 2 : 2.048V full range
  • 3 : 1.024V full range
  • 4 : 0.512V full range
  • 5 : 0.256V full range

For exemple Sensor12 S2 set single-ended mode with 2.048V full range while Sensor12 D1 set differential mode with 4.096V full range

Thank you for the explanation! This is helpful and what I needed to finish my project. Great work all around by group Tasmota :D

Do I have to save the mode?
Sensor12 S3 works fine for me, but after a restart it is always S0 again.

Thx for reply, I tried:
Rule1 System#Boot DO Sensor12 S2 ENDON
Rule1 System#init DO Sensor12 S2 ENDON

the rule has been confirmed in the console

I will send the console output later

You did make sure to also enable the rule set?

[FransOv]

Thx for reply, I tried: Rule1 System#Boot DO Sensor12 S2 ENDON Rule1 System#init DO Sensor12 S2 ENDON

the rule has been confirmed in the console

I will send the console output later

Command should be:

Rule1 on system#boot do sensor12 s2 endon

In addition to fixing the bad command, also make sure to also enable the rule set
Rule1 1

Thanks alot Mates,

You are right @FransOv I miss the "on" after "Rule1" -.- so the rule was done after startup but not on the trigger and that confused me.

Its fixed :)
