Oh dear. Approval Factor is down the pan.
I got some temp sensors to set up alarms if the fridge or freezer get too warm.
After a few readings that were obviously a bit "out" a train of thought ensued...
- Find something to compare them against & then implement an off-set.
- Off-sets are more accurate when done at the target temperature.
So I confidently set forth and grabbed a Philips Hue motion/temp sensor, placed it inside the fridge alongside the other sensor and sat back waiting for some comparison data.
This data ALSO seemed to be out of whack. Not by much, but enough to potentially affect a fridge keeping the contents properly cold.
So again, I confidently set forth and placed a cabled food probe (which I KNOW is calibrated) in the fridge and, once more, sat back. The problem with this is that people keep opening the damned fridge so I had to keep waiting until it had been left closed for a while...
AND THEN I GOT SIDE-TRACKED!
Wind forward a couple of days & my better half asks why the kitchen lights keep turning off. We've been down this road with motion sensors before, but I was quickly told that "waving my arms around makes no bloody difference!"
It was only then that I remembered. It wasn't a SPARE Philips Hue sensor that went in the fridge. The lights switch on when the kitchen door is opened, but rely on the movement sensor to STAY on.
I explained what had happened which was met with a peculiar expression that can only be translated as "for the love of god!"
Unfortunately, and at the worst possible moment, my "man brain" then took complete control of my mouth. "You could have opened the fridge to turn the lights back on."
So, I've invented the world's biggest light switch and earned myself several thousand negative Brownie points along with the (hopefully veiled) threat of "hoping the sofa is comfortable."
