Occasionally, when sending my harmony hub a command in scenes, for whatever reason, the first attempt can fail. I’ve never gotten to the bottom of this but ultimately, re-trying the command a second time always works.
I have written some simple LUUP code which checks the state of harmony 5 secs after issuing a command (like “all off”) to confirm it has worked and if not, I send the command again. This is working well but I’m wondering if the plugin already has an in-built re-try mechanism which I’ve not yet discovered? If not, it might be a nice future enhancement if possible.
