I’ve been noticing that, on occasion, maybe once a week or so, OH2 cannot communicate with my Wemo devices. I have a Wemo link communicating with 3 Wemo dimmable bulbs, so it may very well be the communication with the link is lost. I can still use the iOS app to control the bulbs when this happens, but I cannot control them through OH2. Their state is not reported correctly and attempting to toggle their state fails. A restart of restart the OH2 service resolves the issue and everything works fine for a couple of weeks. Is this a known issue with OH2/Wemo link running on RPi3? If so, I can set a cron task on my RPi 3 to restart the service weekly. Just curious if there might be something else that might be the matter.
Just to give a more complete picture of my setup:
I use a python script via a cron task to toggle the lights morning and evening and it logs its activity to the console. The script is indeed launching, as the logs report, except when the problem occurs, the lights do not toggle as expected. Manually running the script fails as well.
