I've always wondered whether you could measure the power usage of the mosquito thingies (perhaps rather the diffuser that takes the bottles with liquid) and then pick up that it might be empty based on the power patterns.Damn, missed this special by a week!
Getting one for my mosquito burner. No more replacing pads every night or turning it on and off. Only need to replace the liquid every 45 days (or we'll see how long we can stretch it with a smart switch). And will set up a push notification after 45 days to remind me to replace. Sorted.
But yeah, the idea to at least time control it more intelligently (i.e. when sun goes down mosquito burner comes online) makes a lot of sense!
