ChristianI need ideas about an outside thermometer. Requirements: It should join the wlan, ideally POE (okay, yeah, I know). AC is available. No cloud, local API or MQTT.

Krahabors@chris Any version of ESP8266/ESP32 with tasmota on it. Easy for anybody familiar with soldering iron, but a lot can be found ready-made. Works with MQTT, automatically recognized in home assistant, etc.
I have about 30 such devices in multiple locations.

alinkenbach@krahabors @chris did just that today with an ESP32+BME280 and had a go at connecting it via Matter instead of MQTT. Easy peasy.
@alinkenbach @krahabors The more I read up, the more convinced I am to use a ESP32. Sigh.
@chris for simple things esp8266 works well, as long as you do not need encryption etc. @alinkenbach
@krahabors @alinkenbach I am so bold to wager that my outside temperature are not that sensitive of data. I might get away with this. Barely.
@krahabors Yeah, I bought myself a starter kit with assorted stuff, ESP board and a DS18B20. Heating up the soldering iron...
@chris the simplest way is to use "Wemos D1 mini" or it's clone - it's tiny, it has everything onboard, it can be stacked. You just need to connect sensors or whatever needed. Most already have some old micro-usb chargers in their drawer for power and only a micro-usb cable needed for flashing.
Make config backups, these fail sometimes. Noisy or unstable power may cause loss of config or ROM contents completely.
