Hi,

you should use the following YAML format for your filters

filters:
  - lambda: |-
      static float total_value = 0.0;
      total_value += x * 0.01;
      return total_value;

Thanks for the reply. I thought thatā€™s what I had.

Wordblindness is topping me seeing the difference.

Add an indent under the lambda line.

Hello, if the question regarding hardware was for me. I gave the answer Iā€™m a earlier post (September 2019)

i used a Wemos D1 with a A3214LUA-T Hall Effect Switch

I also gave all the explanation regarding the connections to the esp8266.

If needed I can post a picture of my connection pcb.

Hi! Do you have any idea why template platform in your example returns NAN and pretty much doesnt work anymore in HA 2021.12.xx?
It has driven me nuts not being able to get your example working. Any template sensor fails to reference other sensor values with your lambda example

- platform: template
...
  lambda: |-
      static float total_value = 0.0;
      total_value += **id(gaz).state**;
      return total_value;
...
