Is there such a thing - on BezosCo or Pimoroni et al - as a tiny thermometer module that connects to your WiFi? No display, no controls, just a little blob you stick somewhere and it reports temperature back.
I can't seem to find anything, at least cheaply. Perfectly practical to make, but I'm sure there must be such a device being churned out in quantity, if not on BezosCo, then maybe Alibaba.
@porsupah I have some, but they use ZigBee. It'd be easy to build some with ESPHome
or get one of these, there should be documentation for the api somewhere since Tuya stuff works with Home Assistant https://de.aliexpress.com/item/1005003985772680.html
@porsupah a Zigbee dongle + Home Assistant works great for me, I've got a bunch of lights and remotes (IKEA and others)
@porsupah I have a CC2652P-based stick off of ebay on a Pi 4, with a USB extension to get it away from the Pi's radio
@noiob Ha! Handy. _^ I need to pick up a Pi or similar - got various boards, but they're all work's, and something capable of something like Raspbian would open more possibilities, nice as ThreadX is.
@porsupah the Pi 4 has been a very capable lil device, it's running OpenMediaVault (not ina container) and HA in a container and barely breaking a sweat
@noiob Definitely, it does seem like a genuinely desktop-capable device, within the obvious memory/storage constraints. (Which I'm delighted about, being a long-time ARM fan =:) Thinking I'd like to try a single-user glitch instance, to become familiar with that technology jenga tower and its care and feeding.
(Hm. Wonder if anyone's brought some kind of OS to Red Pitaya.. would love to lay my paws on the basic version: https://redpitaya.com/product/stemlab-125-10-diagnostic-kit/ - Zynq 7000 series at the heart, a large FPGA with a couple ARM cores)
@noiob Ahhhh! That's perfect! Many thanks.
I suppose a Zigbee gateway wouldn't be a big matter either. (I've got a Philips Hue setup, but of course, they tend not to be the epitome of openness)
