Hello @ all,
i have three 4262 temperature sensors and i want to get three temperatures to transmit them via mqtt to my iobroker server.
I have got this table from the manufacturer of the senors.
Can you give me an advice if this is possible with an esp8266 d1 mini (or any other device) for example with espeasy (or something else)?
Thanks a lot in advance for your help / support.
should be possible - how easy depends on the existance of support libraries etc - do some web searches
e.g. if there is no existing Arduino library which supports the 4262 sensor you will have to implement your own - could you give a web reference to the device?
using ESP32 microcontrollers I have used MQTT to send data to the remote cayenne desktop and to Node Red on a local PC
Hello,
i just got this information from the manufacturer (Bosch) from the sensors:
This is the device:
Bosch digitales Thermometer 7747201004 | wärme24.de (waerme24.de)
I have three of them. I want to cut the cable, connect it to a device (e.g. ESP) and then transmit the temperature to iobroker (via mqtt).
Sorry, but i could not find a weblink or anything else. Getting the information i have, was already a little bit difficult ;-).
ask Bosch for a datasheet which describes the interface etc, e.g. RS232, RS485, I2C, SPI, ????
without that you are lost!
also do they have example code in C or C++
Is is not simple the resistance value of the ntc which delievers the information? I want to cut the cable (i think 2 veins in the cable) and connect them to the ESP.
I think there is no interface. Or am i wrong there?
