@metalrooster: you are right that the current IFTTT support in the firmware is mainly geared towards notifications. The reverse direction (i.e. using IFTTT to send commands to OpenSprinkler) actually just requires port forwarding and doesn’t really require firmware support. More specifically, that just relies on the ability of IFTTT server to reach OpenSprinkler, and currently the only way is to go through port forwarding. We actually have a blog post about how to get OpenSprinkler to work with Amazon Echo, through IFTTT:

@wheelw: I believe the PIN_FREE_LIST fix for OSBo is already integrated into the repository:
