Oh just remembered @Farmer-Ed’s work with NodeRed: farmOS, NodeRed, Home Assistant etc - #11 by Farmer-Ed
Specifically:
So, I’ve been experimenting with reading and searching logs with Node Red and so far it’s going well, I created a flow that searches observations for the term “Due Date” and updates a Google calendar with the dates. Some thing simple to start with.
The flow is here: FarmOS-Node-Red-Flows/Calving-Calendar-Flow.json at main · Farmer-Eds-Shed/FarmOS-Node-Red-Flows · GitHub
Perhaps that could be an alternative to explore, in lieu of (or while waiting for) iCal integration in farmOS itself…
