You said “openHAB system getting a false message that a station has turned off immediately after being commanded on” — can you elaborate on that? In what way does it get a false message that a station has turned off? The HTTP API only returns a status code after a command has been sent to it. If you send a command to open the zone, it should send back a {“result”:1} if it’s successful. The message does not carry any information about whether the zone has turned on or off. Or did you mean that you are using OpenSprinkler’s IFTTT notification to notify OpenHAB? I am just confused in what way is the controller sending back a message to OpenHAB?
