I started my system this Monday as the morning freezes were gone and the lawn needed watering.
At the moment I am running with manually setted percentage, set from Node-Red via querying the Weather Service runnning on an RPi and I also monitor the actual percentage on a graph.
I used to run OS with a wired Ethernet connection, but I had some issue and switched over to wireless. The gateway for my Froggit/Ecowitt weather station is also located in the same room and needs wifi anyway.
I also don’t know where to start with the investigation.
I guess I will leave it this way and hope to have reliable operation this summer.
