I know this topic has been discussed before, but all of the threads relating to it that I’ve been able to find are pretty old, so I was hoping there might have been some developments in the area that my Google Fu has been too weak to unearth.
So…does anyone know of at least one good off-the-shelf ST compatible temperature sensor that:
- Has an operating temperature range that extends below 0°C/32°F.
- Can reliably transmit from inside of a freezer (I’d prefer to avoid closing the door on a sensor wire if I can help it).
- Has a reasonable (yes, that’s quite subjective) battery life at freezer temperatures.
I know that RF from inside a metal box like a freezer can be problematic, but I’ve seen several people cite examples of sensors that have done it. And while my hub is about 30 feet away on a different floor (with a couple of walls in between as well), I have multiple repeater-capable Z-Wave and Zigbee devices spread out between them. Combo units with open/close sensing would be nice, but that functionality isn’t an absolute requirement.
So, let’s go the phones. Hello, Albuquerque…you’re on the air.
