i’m working on something like " smart laboraory " , so i’m trying to make a smart voltage sensor that can read voltage and monitor it on a mobile phone using openhab ( through mqtt ) .
my imagination is to use a voltage sensor with esp8266 module communicating e.g. via MQTT with OH.
i need any help about :
- the circuit diagram of the sensor and esp
- the program that would be loaded on esp
- config of openhab ( things , items , rules )
see the other thread.
When I did my thesis work I did the complete research/development on my own.
Not sure if I even already had internet access at that time. At least not for the research/development part.
Use one of these, and flash it with Tasmota (Google it). That’s your first two demands (esp+sensor, firmware) finished.
When you’ve got those done, then come back with your attempts at integrating into openHAB and we can help.
Please don’t open multiple threads on the same topic.
