Compiling of OnlineHumidifier-openHAB.ino gives error

[semaf]

Hey,

There are missing some libraries and compiling has problems. Would you fix that?

cheers

Hi semaf,

Thank you for issuing first report on this repository :smile:

Please post the compilation log so I can check where the problem is. What version of ESP8266 core you are using? What is your version of Arduino IDE?

Well there are a lot of Errors due the DHT, RF433, Emoncms etc.. I would say you should make a clean Sketch without additions of RF433 or anything else.. Just DHT22 + ESP8266 + OPENHAB + MQTT and that would be clean enough.

Errors: #1 just compiled:

OnlineHumidifier-openHAB:31: error: 'D2' was not declared in this scope
OnlineHumidifier-openHAB:44: error: 'D1' was not declared in this scope
OnlineHumidifier-openHAB.ino:45:37: note: in expansion of macro 'RF433_TR_PIN'
'D2' was not declared in this scope

2 corrected Pins to 2 and 14 instead D2 and D14:

If I begin to clean all Errors it will take more time than to write a new one :dancer: Thats why a clean version would be great :)

I see your point and thank you for taking time to document it. This is a good opportunity to expand this repository with another section (Just DHT22 + ESP8266 + OPENHAB + MQTT).

• Removing Emoncms is easy to justify. Charts may be done directly in openHAB.
• What about RF433? I need to provide some reasonable way to automatically turn humidifier on and off for closed loop control. What would you provide instead?

A delay is also fine. Mostly Humdity and Temperature Sensors are never going to be turned off but adding a delay would be enough.
