I have reinstalled the plugin multiple times, checked the config.JSON seems to match your examples.
Desperate to get this first raspberry pi project working.

from homebridge-dht.

That instructable is out of date and doesn't match the current configuration

Updated instructions are here - https://github.com/NorthernMan54/homebridge-dht/blob/master/Build.md

But with that said, this error means that the plugin did not install No plugin was found for the accessory "Dht" in your config.json.

Did you get any errors during the install ?

from homebridge-dht.

No errors installed perfectly.

from homebridge-dht.

I checked the GitHub instructions too still no joy. I have also reinstalled the plugin multiple times

from homebridge-dht.

i have completely flashed the imageback to the pi and started again, now when installing bm2835

humm, what is in this file src/test-suite.log ?

from homebridge-dht.

from homebridge-dht.

Sounds like a permission issue with /dev/mem, try running the test again with sudo

from homebridge-dht.

Update:
Library installed.. took another re-flash of the micro Sd and not to install the web ui until after.

See logs now not temperature readings

This version should not use [cputemp] cputemp function failed: Error: spawn cputemp ENOENT for the DHT Temperature. What is in your config.json ?

The error Error: [Error: failed to read sensor] is coming from the library node-dht-sensor. Do you have the wiring correct ?

from homebridge-dht.

Wiring is exactly to your specs
