Dew Heater Noob issue

[Deepblue12]

As a total noob to coding in general, i'm really struggling with getting the allsky_dewheater.py to work.
I running a DHT22 temp/dew sensor on pin 7 and a relay to my heater on pin 12.
"arguments":{
"type": "DHT22",
"inputpin": "7",
"heaterpin": "12",
I'm stuck with what setting to add to "extrapin""", and "i2caddress": "", For the 12c i've run i2cdetect -y 1 but no addresses are showing.
I know both relay and temp sensor work ok as i have tested them through Raspcontroller.
Biggest issue is when i run allsky_dewheater.py via Thonny i get this error:

%Run allsky_dewheater.py
Traceback (most recent call last):
File "/home/gary/allsky-modules/allsky_dewheater/allsky_dewheater.py", line 19, in
import allsky_shared as s
ModuleNotFoundError: No module named 'allsky_shared'

Any assistance greatly appreciated.

Few things here

1. The modules are configured using the module manager in Allsky, there is no manual editing of anything required. For the dewheater

• Goto the module manager and in the periodic flow add the dewheater.
• Select the DHT22 in the drop down
• Set the pin in 'Input Pin' that the DHT22 is connected to
• Under the 'Heater' tab set the pin you are using to enable the heater

2. The modules cannot be run outside of Allsky, they are not designed to run standalone or via Thonny
3. Whilst there are i2c DHT22's available most are not so you wont see anything in the i2cdetect unless you have an i2c based DHT22. I am assuming you dont as you mention its only connected to pin 7

Hope that helps :-) There is quite a lot of info in the documentation on the modules so have a read of that as well if you have not

If not please feel free to ask any questions.

something a bit strange. I have my heater relay on GPIO18 (Pin 12) but when i select it on the GUI screen, GPIO10 (Pin 19) is also highlighted at the same time!
If i save it this then displays Heater Pin 18 on the control settings page?

Thats a bug which I have just fixed ready for the next release see AllskyTeam/allsky#4071
