Hi Marksev1,
Thanks for the question, I agree I do not know how safe or stable in fault situation the setup is. I solved this by adding a traditional timer valve upfront on the groups. Meaning there is a specific time slot wherein the groups can be used to irrigate the plants.
My appologies for the late response, and a good question.
The code btw runs like a charm except that exception catches have not been addressed (quick and dirty). Meaning if a device isn’t available the BLE stack could get bogged because I did not add a timeout/retry counter.
In the summer I will look at these functions. If you like I can post a version combined with myflora sensors.
Kind regards,
Roy
