Tasmota: No DHT22 sensor selectable

Created on 23 Feb 2018 · 5Comments · Source: arendst/Tasmota

Hi,

i am on 5.12.0c and use the "Generic Module" on a bare ESP8266.
On GPIO0 i have a DHT22 sensor, but i cant select it in the configuration menu.
Is this not available with the module i use?

EDIT: I compiled with this enabled: env_default = sonoff
Thanks!

Use "03 SI7021", that's the DHT22 sensor too.

See master/v5.11.0:

Add support for iTead SI7021 temperature and humidity sensor by consolidating DHT22 into AM2301 and using former DHT22 as SI7021 (#735)

Thank you.
I did not find a mention of this at https://github.com/arendst/Sonoff-Tasmota/wiki/Sensor-Configuration

There is: see subsection Single wire sensor - DHT22 (3), AM2302 (3), AM2321 (3), SI7021 (3) are all the same sensor (=3) type.

Hint: Use also github _Search_ function

@dYna77 if this is solved please close this issue

Issue is closed, but answer should be corrected to say he/we should use the AM2301 selection when using the DHT22, if you go look at the issue referenced with the quote, the longer explanation helps better clarify which should be used for what. Apparently, the AM2301 uses the same handler as DHT22 so they "consolidated" them into one selection. Then took the old DHT22 selection and changed it to the SI7021.
