ESPHome Blitzwolf SHP2 configurations

I have a couple of Blitzwolf SHP2’s and I noticed that they are different from each other. So these are my configuration files. The difference is in the GPIO numbers.

First configuration:

substitutions:
  plug_name: switchbw_1
  plug_ip: !secret switchbw_1_ip
# only change upper plug_name and plug_ip  
# put a secret.yaml file in the map with switchbw_1.yaml
  plug_gw: !secret gw
  plug_nm: !secret nm
  plug_dns_1: !secret dns_1
  plug_dns_2: !secret dns_2
  wifi_ssid: !secret wifi_name
  wifi_password: !secret wifi_code
  current_res: "0.00221"
  voltage_div: "955"
  api_pw: !secret api_password
  ota_pw: !secret ota_password

Thanks for taking the time to document this!

Was struggling with my Teckin SP23 until I finally found your post detailing the GPIO pinouts!

You’re welcome!

Hi there!
I’ve just registered to say thank you for this. very nice.

Though I have a question, is there a way to have the total energy sensor? This is important so that the utility_meter component can work and calculate the “today, yesterday, this week, last week, etc” energy sums.

Hi Andrew. For as I know there is no total energy sensor or attribute. You probably have to create your own sensor.

Thanks!
Actually I found out that the utility meter component works the same way with a daily energy counter, which solves my problem :slight_smile:
