temperature sensors

I have just installed a DS18B20. I bought it for €0.85, complete with wires. But you need to get a 4.7k ohm resistor, which is not expensive. It is not waterproof and it does not read humidity. It is just a thermometer. Very straightforward installation.

@seychellch
OK but I would measure the temperature of various rooms, so I was thinking about wifi or zeegbee sensors without using the gateway or a cheap gateway -
@s-monti-74
zigbee does need a gateway since it talks on another protocoll than regular wifi (even if it is on the same bandwidth).
try building esp8266 nodes with temperature sensors and run espeasy on them. should cost you around 10-15usd each, without power supplies.
otherwise you have ready made Shelly Temp Sensors that runs on wifi, they are a bit pricey though.Shelly :

@broberg Not bad the “Shelly solution” but with which module can I read the values ?
-
@s-monti-74 Don’t think there are any modules written for shelly yet. It’s not impossible but don’t think anyone have done it.
Same goes for the esp8266, don’t think there are any modules for temperature for those either.

@s-monti-74 @broberg Sadly, I do not have any magic solution for this
-
probably found a solution by next now
but I use a combination esp8266 and mysensors with dht22
-
@ardenking said in temperature sensors:
esp8266 and mysensors
no i haven’t find yet
I’ m trying with openhab and home assistant to read shelly h&t but I don’t understand how to setup
dht22 are connected to the PI ? do you have one Pi in each room ?
thanks -
I have a SmartThings hub and Alexa and I’m looking for a cheap, reliable way to measure temperature across the house. What I’ve tried:
Xiaomi Aqara temperature sensors, which are super cheap but are reliable if and only if they’re close to the hub - they quickly lose connection and won’t reconnect if they’re distant (repeaters make it worse).
Centralite temperature/humidity sensor seems to work reasonably well, but needs CR2 batteries and goes through them quite quickly. Looks like they’ve stopped making them anyway kamukta
Samsung Multisensor, but it seems wasteful to have 6 measurements and only look at one of them
Boesch motion sensor, ditto
VIsonic door sensor, ditto, also only reports temperature a couple times a day
Are there temperature (or temperature/humidity) sensors for Zigbee or Z-wave that cost $15 or less that I can actually expect to work for more than a week at a time?
