Device shows wrong temperature after updating from 12.12.4 --> 12.12.5

[Gandalf8266]

I have a ESP8266 microcontroller with a DHT22 connected.
Device works fine so far, but on every update it shows wrong temperature (-99°C) and humidity (0%).

It happens on every update, but now, I made screenshots bevor und after update.
It's easy to fix, I only disconnect from power and connect again, but this is annoying.

The config is here:
{"c":{"o":0},"a":[{"t":24,"b":[],"n":2,"g":2}]}

I have attached screenshots bevor und after update.

It is hardware related. GPIO 2 is pulled up and high at boot. This can not be changed by firmware. Better, use other GPIO.

Hi, @RavenSystem I get this -99 also on GPIO 14.

config -
{"c":{"io":[[[14],2],[[2],2,1]],"l":2,"n":"t_bathroom","i":1,"b":[{"g":0}]},"a":[{"t":25,"s":5,"g":14,"0":{"h":[{"h":"10.0.1.8","p":5556,"m":1,"u":"characteristics",
"c":"{"characteristics":[{"aid":2,"iid":9,"value":false}]}"}]},"1":{"h":[{"h":"10.0.1.8","p":5556,"m":1,"u":"characteristics",
"c":"{"characteristics":[{"aid":2,"iid":9,"value":false}]}"}]},"3":{"h":[{"h":"10.0.1.8","p":5556,"m":1,"u":"characteristics",
"c":"{"characteristics":[{"aid":2,"iid":9,"value":true}]}"}]},"5":{"a":0}}]}

The wires are soldered and changing gpio will be painfull. Any other options I can do?

Strange, but sometimes it shows the correct reading, but sometimes -99. What could this be related to?

I replaced all DHT22 temperature sensors. I no longer encounter this issue.
