IoT-OnOff App for iOS devices?

by MiltonConnor on Wed Oct 28, 2020 4:33 am

Has anyone out there successfully connected their IoT-OnOff App to

I have several published feeds from my industrial PLC that are working nicely, and the App will connect to my account in the broker, but when I do, io.adafruit returns the following error message:
MQTT ERROR: <my device ID> <my IP Address> SUBSCRIBE to topic `+/iot-onoff-export-widget/26595702` rejected, not a valid resource topic

This, in spite of me deleting all of the sample dashboards and groups that came with the app.

Trying to figure it out. I believe when you connect to a broker, it tries to connect to your configured feed as well as the export-widget feed. If you malform your AIO feed name, you'll get an error for that as well.

Looks like a cool app, but I can't get it to publish data to an AIO feed. :/

EDIT: Oh! Actually, no, the problem was blindly trusting the FAQ on their website. It says username/seeds/feedname, but it's actually FEEDS, and AIO doesn't throw an error in that case.
