Hello Niwa!
I was doing maintenance on my home network this morning, and I didn’t notice that my 2.4Ghz wireless AP dedicated to IoT devices did not properly come back online. This occured 4-5 hours before lights off in the grow tent. An hour after the lights were supposed to shut off in the grow tent, I noticed they were still on!
During that time period, the SSID was advertised, but network connection was unreachable beyond the AP. Restoring the wireless network was insufficient, I had to unplug and replug the Niwa for it to reconnect and respect the recipe.
This is the first time I’ve had this situation happen, my network is usually stable. It got me thinking though, I assumed the controller would have a cached copy of the running recipe and still run properly if the wireless connection goes down. But it doesn’t, is an active wireless connection required at all times?
