Hi,
I’m new to using Luup, and I’m trying to write some code to send an alert when a variable has changed. Specifically, I want to know when each of my battery-powered z-wave thermostats wakes up. Currently, I have added the following to my Startup Lua on my VeraLite (using UI5), which monitors the value of the LastWakeup variable on just one of my thermostats, which has id 141:
local function stellaNotify(lul_device, lul_service, lul_variable, lul_value_old, lul_value_new)
luup.log(“Sending a thermostat wakeup alert”)
local status, result = luup.inet.wget(“http://xxx.xxx.x.x:xxx/?stellaZWakeUp”, 5)
luup.log(status)
end
luup.variable_watch(“stellaNotify”,“urn:upnp-org:serviceId:ZWaveDevice1”,“LastWakeup”, 141)
At the moment, the code doesn’t appear to do anything - no errors appear in LuaUPnP.log - but equally, the alert never seems to get sent, nor do I see the log entries that I’ve added to the stellaNotify function, which makes me wonder if any of the code is actually being called. I can see that the value of LastWakeup changes though - here is the log corresponding to when I manually wake up the thermostat:

I’m not sure what the ‘dongle is in a bad state’ warning refers to, but I’m assuming it’s unrelated to my current problem. Any advice or ideas why this might not be working would be much appreciated! Perhaps putting it in the startup Lua is inappropriate for some reason?
