Code esp8266

[Azza1979]

Hi

Could you please tell me how I get the code onto the nodemcu. I have homebridge up and running on raspberry pi but just have little knowledge of the esp8266. Any help would be great Thanks Aaron

The nodeMCU has a micro USB port that you can plug into your Mac. I used the Arduino IDE to upload the code onto it. You'll need to install some stuff to be able to upload to it but a simple google search will help. If you have a barebones esp8266 you'll need a Serial to USB adapter (Google CP2102). Good luck!

Ok so I'm sort of there, but now I have done the code onto the Nodemcu and go to this address http://enter_ip_address/temperature (but with my IP address) it comes up with this {"temperature":263}.

I have installed npm install -g homebridge-http-temperature and updated my json but now when I run homebridge I get this

[4/20/2017, 8:53:42 AM] [Mum & Dad Temperature] Requesting temperature on "http://192.168.1.69/temperature?format=json", method GET [4/20/2017, 8:53:42 AM] [Mum & Dad Temperature] Error processing received information: undefined

Any suggestions

The only thing I can think of is that either HomeKit or the plugin is rejecting the high temperature. If I remove my sensor the temperature value either drops to -83479825 or 2147483647 and HomeKit displays "No Response". Maybe try removing the ?format=json after the URL but apart from that I have no clue. Could you paste your config.json (remove passwords, etc if there are any)?

Does it mater that I'm using a DHT22 sensor ?

[Azza1979]

Ok so I just took the data wire off and now it works properly reading -50. So Im thinking it has to do with the dht22

[greenywd]

Ah, check the code in the DHT22 branch then - I got one myself yesterday and added the code for it. You'll need to install the Adafruit Sensor Library if you haven't already to get it working (I'm lazy 😅).

Bit of fun information, the temp sensor i was using before was analog so I had to do a bit of witchcraft to get it working (not really, but it was a fun thing to mess around with). The DHTxx is digital so connecting the data pin to an analog pin probably doesn't work the way it should 😛

As the DHT22 supports humidity, you can swap to the homebridge-httptemperaturehumidity plugin to get a humidity accessory as well. The sensor I was using before didn't support humidity, so I had no need to use it.

I got it all going thanks for the help mate really appreciate it.
