I’m running hass.io 0.61.1 and are seeing these issues in the log.
ERROR (SyncWorker_4) [homeassistant.components.sensor.speedtest] Error executing speedtest: Command '['/usr/bin/python3', '/usr/lib/python3.6/site-packages/speedtest.py', '--simple', '--server', '2229']' returned non-zero exit status 1.
They didn’t begin after upgrading to 0.61.1, they been there for quiet some time now…
