Using 8 relay HAT

[t4islander]

Hello, starting with total newbie to this :)

I have a Raspberry PI that I have connected to a 8 relay output board, its a HAT I think because I have landed the RPi directly to the board. I'm able to toggle relays on and off using some pretty generic Python scripts but when I installed SIP and run the program none of the relays are activating. I have been using the following code to test with in Python as an example:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)

GPIO.setup(26, GPIO.OUT)

GPIO.output(26, GPIO.HIGH) #relay off
time.sleep(.5)
GPIO.output(26, GPIO.LOW) #relay on
time.sleep(10)
GPIO.output(26, GPIO.HIGH) #relay off

Is there a configuration somewhere I can change to use this board? I have GPIO PINs 5,6,13,16,19,20,21,26 that are working in my own Python but would rather not try to invent something that already exists and is really well built!

ok, so quick update - I installed the relay_16 plugin and now when I run manually SO6 fires relay 4, SO7 fires relay 6, and SO8 fires relay 7 on my board. Is there somewhere I can update the GPIO mappings? I looked at the relay_16.py file and see the mapping there. I was thinking I could list the GPIO PINs I'm using there but I can't update the file, and don't know if I should. Any help much appreciated :)

Ok, trying to incorporate the Weather based plug in to moderate water use I am getting the following error from the service. Any ideas on how to overcome?

Weather-based water level encountered error:

That plugin was modified by several contributors. I am testing but this may take a while to debug.
I will let you know how it goes.

For now it would be best to disable it and get the rest of your system running.

I was able to run the plugin successfully.

When I deleted the Openweather API Key I got a 401 Unauthorized error.
When I deleted the location info I got a 400 Bad request error like you got.

Make sure the location info is formatted as described in the Help page.

Thanks Dan - again really appreciate the help with this. I went ahead and connected up the relays to the sprinkler valves and it's working like a champ. I'll double check my settings and continue to troubleshoot.

Update: Well I went it to check the settings and the call was successful! Looks like I'm on the path to green lawns! Thanks again for the help and responses, have a great day.
