Adding more pins??? #17

Open kskenyon opened 7 years ago

kskenyon commented 7 years ago

I tried adding more pins by editing config.json in homebridge but I get an error starting up homebridge. I can't figure out why. Any ideas? It works fine without the added pins in config.json

I'm trying to control the LEDs on an Explore Hat from Pimoroni

Can you try clearing cachedAccessories? (As per this thread: https://github.com/rsg98/homebridge-gpio-wpi2/issues/12)

I figured out that I can only use GPIO2 and up for "name:" and have it work. I have four outputs working now. I'm not sure how many "name:"s I can add without experimenting. I'm not much of a javascript programmer to understand what configuration setups will work. I'll try the cache removal and see what happens. Thanks

I just figured out how to fix this problem you have to delete all the text in the file called cachedAccessories in the "/home/pi/.homebridge/accessories" there the file is. when you have entered the name you want, and then it should work. ;)
