Error subscribing, lost connection

[palmtreefrb]

I'm using the gpio component and it looks like it is subscribing to the topic before mqtt is connected.

component.py

from pysmartnode import config
import gc

gc.collect()
from pysmartnode.components.sensors.ds18 import DS18
gc.collect()

from pysmartnode.components.switches.gpio import GPIO
gc.collect()

ds18 = DS18(pin=27)
config.addComponent("ds18", ds18)
gc.collect()

gpio = GPIO(pin=15)
config.addComponent("relay", gpio)
gc.collect()

I see 2 problems here: 1) How did you make your sensors be registered this early in the program schedule? This is not the correct way. You are not using "components.py" I presume? 2) I should have made that error message a debug message because it is not actually an error. If the connection is lost, the subscription will automatically be attempted again once the connection is available again. So in the following log lines after the ones you posted, there should be lines like "_subscribing breweryaiss/4c11ae713994/GPIO/15"

Yes, I edited my above post to show my component.py

[kevinkk525]

component.py is not loaded by pysmartnode, only components.py but that is probably what you have. I just checked that again and it's correct, the components.py is loaded this early. but as I was mainly using the esp8266 until recently, I had no connection issues because the esp8266 is typically already connected to the wifi at that point.

But there really is a bug, it doesn't subscribe the topics after connecting. I will fix that asap. Thanks for the report.

Sorry, typo it is components.py

[kevinkk525]

I fixed the issue. Was a simple oversight. I updated the mpy archive in the release with the new mqtt.mpy that fixes the issue. However, that module doesn't use variable annotations so it should work as a .py file too.

Ok, it is working now. Thanks!!!
