Hi,
maybe it is a silly question, but i couldnt find anything for it. Is it possible to submit sensor values from a network device to the openhab2 server?
I have an Arduino with ESP8266 here and want to send some temperature values to the openHAB-Server.
My best idea was to create a webinterface, where i submit my data and get them via exec-binding. Is there a better or easier way to get the temperature value to openHAB?
Alternatives: MQTT and/or HTTP
Edit: some examples:
Reset ESP8266 via http (ESPEasy firmware):
Switch RebootESP8266_3 "Reboot" { http=">[ON:POST:http://192.168.X.XXX/?cmd=reboot]" }
Read temperature via MQTT:
Number Temperature "Temperatur [%.1f °C]" { mqtt="<[mosquitto:/esp8266four/temperature/shadow:state:default]" }
If you search the forums for ESP8266 you’ll find a number of people who have worked through the situation in a few different ways.
The joy of OH is it’s ability to work well with many different methods. Find one you like and run with it!
Thanks for all the Replys. I think i am going to write my own little PHP-Script, because i have a Web-Server with mySQL running and send my Sensor-Values to the PHP-Script.
OpenHAB just needs to pick the values then from the Server via Exec-Binding or HTTP-Binding.
I would second MQTT and ESPEasy. Made to do exactly what you want to do. No need to reinvent the wheel.
MySensors is also a good option for battery powered sensors.
Thats my Solution i made today so far:
Not perfect but simple.
Submit SensorData:
index.php?controller=submit&sid=abc&var=123 //Submit SensorValue 123 under the SensorID abc
Get SensorData:
index.php?controller=get&sid=abc //Get Sensor Values from SensorID abc
Example Output:
<sid>ds118</sid> <var>22.33</var> <updated>1488312335</updated>
This can be filtered with regex to get the right value.
The table gets created automatically on the mySQL server if it not exist. Sensor-Values will be added or updated if the sid already exists.
