Multiple ADS1115 on ESPHome

1800Power · October 11, 2020, 4:14pm

Hi,

I´m using an NodeMCU with 4 SDA1115 attached.
All 4 are working (tested wir Tasmota-firmware).
With ESPHome I´m only able to get information of one ADS115 with its 4 channels,
because I don´t know how to build the correct configuration.

Can anyone please help me to get the other three ADS1115 to work?

Kind regards

Frank

My configuration file is:

i2c:
  id: bus_a
  sda: D2
  scl: D1
  scan: True

ads1115:

I have the same problem, is there a solution?

Hi Patrick,
as a got no answer here, I decided to try get a solution by myself.

Here is my working configuration as an example

Thanks for this. Worked perfectly for me once I got through the trials of getting a Wemos D1 Mini Pro to flash with ESPHome. I never have problems with nodemcu’s but I needed the external antenna for this job.

Thanks for sharing. works perfectly with wemos d1 mini and 2 ADS1115.

Thanks for sharing your code, it just gave me my solution
