Domoticz

Hello
Has anybody found something for this :
a temperature sensor to place/attach/clamp onto the surface of a pipe/radiator etc to report temperature to Domoticz
-> I'd measure surface temperature of pipes in/out of my heating system, of radiators etc

Like the Digoo R8H but with a kind of external probe ?
Digoo R8G: https://www.banggood.com/Digoo-DG-R8H-4 ... 78108.html

Been looking on Banggood and Aliexpress but no luck so far - I maybe have the wrong keywords

At worst I guess I could desolder/add cable/resolder to get the sensor outside the R8H casing, but would rather not..


Thanks !

Well there are several approaches

1)if you have a few Arduinos + NRF24L01+ modules and some DS18B20
Use Mysensors and create 1 gateway and a sensor/node. The sensors can use DS18B20, this temp sensors you can attache to your pipes with strips

DS18B20 temp node:

serial gateway:

2)
If you have an ESP8266 wifi, then you can use this approach instead of using mysensors:

3)
If you have your RPI with Domoticz close to where you want to measure, then you can cable DS18B20 directly to your RPI

Thanks, I will read up on material you provided me with ! wifi or 433mhz are both good for me

I am just not great with electronics and was hoping I had overlooked a simple battery enabled sensor

In fact I'd rather not be dependent on power network because I want to move around the sensors to check different things in the house

Check also NodeMcu with EasyEsp firmware. You can attach which sensor you want, like the mentioned dallas DS18B20. You can put this all together in minutes.
