sensor source

[boelle]

@hugokernel hi, do you know where inside eu i can get the sensors? from china takes to long and i have to pay extra tax

EDIT: i think i will just get a wind direction and speed sensor. I made an arduino weather station and from that i have both rain gauge and bme280

i dont want to get the temp in the sun but if i want to could just add another bme280

Q: could i just repeat like this? i plan to use adafruit sensor and if SDO pin is put to GND it changes from 0x76 og 0x77

i know that pressure will be the same and prob. also humidity, but i'm just looking for working code

  - platform: bme280
    address: 0x76
    update_interval: 60s
    iir_filter: 16x
    temperature:
      name: "${friendly_name} in shade temperature"
      oversampling: 16x
    humidity:
      name: "${friendly_name} in shade humidity"
      oversampling: 16x
    pressure:
      name: "${friendly_name} in shade pressure"
      oversampling: 16x
  - platform: bme280
    address: 0x77
    update_interval: 60s
    iir_filter: 16x
    temperature:
      name: "${friendly_name} in sun temperature1"
      oversampling: 16x
    humidity:
      name: "${friendly_name} in sun humidity1"
      oversampling: 16x
    pressure:
      name: "${friendly_name} in sun pressure1"
      oversampling: 16x

and i forgot to ask, (i cant figure the code yet), but does this part ever reset?

  - platform: pulse_counter
    pin:
      number: GPIO38
      mode: INPUT_PULLUP
    unit_of_measurement: 'mm'
    name: "Rain gauge"
    icon: 'mdi:weather-rainy'
    id: rain_gauge
    internal: true
    count_mode:
      rising_edge: DISABLE
      falling_edge: INCREMENT
    internal_filter: 13us
    update_interval: 60s
    filters:
      # Each 0.011" (0.2794mm) of rain causes one momentary contact closure
      - multiply: 0.2794
    accuracy_decimals: 4

i understand that rain per minute and daily rain are reset, but does the above work as a rain in total that is only reset if mcu is reset(power cycle)

Did you find answers to all your questions?

[boelle]

I think yes

My problem is more checking if my code is right

But not home before evening

But if you have time to check my code for any obvious errors I would be happy

If you change the address, yes, it will work but after that, I don't really see the point of measuring the temperature in the sun ;)

i understand that rain per minute and daily rain are reset, but does the above work as a rain in total that is only reset if mcu is reset(power cycle)

The integration will start again at the beginning but is it really a problem? The assembly may reset often?

i plan to power it from 5v usb adapter so if power goes out it will reset

Temperature in the sun makes sense when summer starts and you want to know if you need a jacket or t-shirt or you can go topless tor. 23. sep. 2021 16.53 skrev Charles R. @.***>:

I think there are much more reliable ways to measure the temperature felt by taking into account the wind, the humidity (dew point?).

[boelle]

good thinking, that escaped my mind totally

will look in to it straight away since i have nothing better to do

EDIT: https://community.home-assistant.io/t/sensor-of-temperature-feels-like/299063/23

seems that its a bit more involved and that everyone has an opinion, its understandable as some will feel cold pretty quick and it also depends if sun is hitting you or you are in shade
