I’m looking for a way to trigger an event when the difference between two different temperature sensors exceeds some threshold … without having to write scripts or code. Is that possible with HS3? I don’t own a HomeSeer hub, but am considering buying one for this use; hopefully something not too expensive, like maybe the a HomeSeer HomeTroller Zee S2.
For the temperature probes, I’ve been looking at Ambient Weather, such as their WS-0265, WS-8482, WS-2801A, or WS-50-C. Does the Simplex/Ambient Weather plug-in for HomeSeer support any or all of those models?
Here’s more about the specific application we’re considering: we have an uncooled space where our big freezer is. We only go in there occasionally (maybe once or twice a day). We use fans in the windows, bringing in air from the outside, to keep the space from overheating and have been just been manually monitoring the temperature (not using thermometers, just how hot it feels), turning it on when it seems like it is probably cooler outside than inside. Basically, we often just turn it on and leave it running all day or all night … not very efficient.
It would be great if we could put the fans on a smart outlet and setup a rule to do this more automatically, with one temperature sensor inside and one temp sensor outside. The rule would be something like “If the temperature from the inside thermometer becomes more than 5° above the temperature from the outside thermometer, then turn on the fan” and a second rule that says “If the temperature inside becomes less than 3° warmer than the temperature outside, then turn off the fan”. I would expect we would experiment with the actual values of those differences, to get the hysteresis value correct.
Any advice on the best way to do this would be welcomed. By ‘best’ – I mean least amount of work, while still being an economical solution. I’m willing to spend a bit more to save time and effort making it work, but still it is not worth spending hundreds of dollars on this project.
Thanks.
