I am seeing this in the HA log file. As far as I can tell, it is causing no issues, no loss of functionality or anything of the sort, but clearly, something has gone wrong with something, I am just not sure what.

You have done it now; you’re infested with gnomes.
Seriously, the only thing I could find related was this; maybe it will point you somewhere?

Feature requests should go in the forum: https://community.home-assistant.io/c/f… eature-requests
**Home Assistant release (`hass --version`):**
0.18.2
**Python release (`python3 --version`):**
3.5.1
**Component/platform:**
sensor.gtfs
**Description of problem:**
I don't see any _actual_ issue here, but since I enabled the GTFS sensor, I often see in my logs a huge quantity of SQLAlchemy related errors. The component seems to be working fine (both in frontend and from automation rules), but…
**Expected:**
No error in logs
**Problem-relevant `configuration.yaml` entries and steps to reproduce:**
``` yaml
- platform: gtfs
origin: 3347699720881315
destination: 3347699720888336

Best I could do - I found a few other links but they seemed so out of the loop and unrelated I didn’t bother.
Pro Tip: Leave shortbread cookies out near your Pi and then whack them with a newspaper. Gnomes can’t resist shortbread.
Well, you learn something new everyday. I will give that a shot and just take care of it that way.

Did you find a solution to this?
I just set up a clean install of Home Assistant using the all in one installer for raspberry pi and I have this exact same error.
Currently the only thing I have modified is the lat long location and elevation in the configuration.yaml.
Nope, no solution found as of yet. But it wasn’t seemingly problematic either so it was not getting a lot of attention from me either.
