    Those look similar to these:
    https://store.wirelesstag.net/collections/all Bit cheaper.

    I have 5 of them, plus the tag manager. Range is good, I have one in the deep freeze, one in the fridge. Also the one in the bedroom is on the 2nd floor, tag mgr in the basement, no issues.
    Those look interesting but boy would the costs add up fast.

    I think you'd end up spending a lot of the adafruit stuff if if you didn't already have a bunch of spare RPi's around. In the end, it's not going to be cheap with any option. My 5 sensors plus power adapters so they can be plugged in to 120V and the tag manager plus shipping was $275. That's a lot for sure, but there's no additional costs outside of it.

    Anyone build a digital dash for their car yet?
    That's all I'd want to try and do.

    Just checking in to say i have gotten a lot of enjoyment out of my wireless tag sensors. Check them like 10 times a week.

    Today it's got me thinking how my unheated detached garage stays 12c warmer in this extended cold weather.

    Is there a calibration on it? Seems like it's reading high. Or you're reading it high. Buy weed stonks don't smoke or drink them.

    If it was the insulation, I'd expect the temp decline to be slower than the outside temp sensor. Looks like the same decline on both. And I know declines.

    Which adafruit sensor tracks your TP hoard? I assume a weight sensor on the pallets? @speedog is probably interested too.

    I'm full straight edge for Feb, so don't think I'm reading it wrong. It matches the readout from my compustar starter too. But yeah, something seems off.

    Cars have a fair bit of thermal mass, if you park a warm car in there once a day that will keep it pretty “warm”.

    I also used to “poor boy” heat my garage by leaving incandescent lights on for a couple hundred watts of heat. Is someone leaving the lights on?

    Considering where you live, does your garage share a party wall? Perhaps your neighbour has a heater?

    Based on that pattern, looks like @ExtraSlow goes out for a coffee break around 2-4pm.

    Wife goes out to pick up the kid from the bus around 4 daily. Yeah. And we do share a party wall with the neighbors garage, but I'm pretty sure it's not heated. Or if it is heated, it's electric only. They have no chimney anywhere for exhaust. Always fun to play detective on things like this that do not matter.

    Decided to check calibration by moving another sensor into the garage. Will report back in morning once I have enough data to chart.

    Glad they're working out for you!

    I honestly wish I bought more. 5 seemed like a lot, but I could use at least 3 more. Should have bought 10.

    Temp sensors are fun

    Although not happy my exterior sensor stopped reporting at 3am. Wonder if it went out of range at minus 29c?

    Probably should have spent te money on the exterior rated sensor. Oh well.

    Just came across these guys https://www.jemrf.com/ and seem to be fairly reasonably priced.

    $12.95 for the module to use a RPi and then $20 for a temp sensor.

    Executes on the TP sales he's found earlier that day.

    Your neighbour could have a heater in his garage. Bonus for you.
    Interesting the floor sensor vs wall. I can definitely tell you while working in an unheated garage, the floor stays way too effing cold!

    Can you plot this data in a stacked area chart so I can understand it better?

    Well, brought it in, thawed it out and put it back out. It's the version that has constant power through USB adapter, so battery wasn't the issue. Graph looks funky now. I like funky.
