A real life example

[sanderlv]

Hi, thank you so much for creating this piece of hardware! It is now so handy to overcome the "issues" I had with the original print. the fact the fan would always auto turn on to 100% >65% hum was annoying and hard to change. I had "arne mauer" his print to arrange thing outside via HA but this did not always work as intended.
Now with this ESP board I can from within ESPhome create automations and turn on "auto" (or off :-)).

I have to change some internals on sensors to get a "fast" reaction on automations. By default in the SHT20 file this was set to 30000. I changed that to 5000 (5 seconds). then I created new sensors for HA with a throttle to 60s.

The result:

I may not be able to quickly react if questions are asked. Don;t be mad then 👍
disclaimer: This is my setup. Feel free to use or copy. But do no blame me for anything going wrong. It's your responsibility.

the change in SHT20:

  // the temperature 5s-30s. So lets poll at 4s, or half the response time.
  SHT20() : PollingComponent(5000) { }
  //was origineel 30000
