GPIO Pins not working for Relays

undefinedbrewing

Morning, relay's aren't working with my 8266 board and it keep saying it can't be connected to. Any tips? I know that GPIO are working because the relay's work with a different sketch and the DS18B20 I have connected works within Brewbench.

Thanks!

Hi. Did you find a solution to this issue? I seem to be having the exact same problem with the 8266 board. The DS18B20 works perfectly but not my relays. I keep getting this error:

Connection error: http://192.168.0.111/arduino/digital?dpin=D2&value=1

Thanks

So I bought a new esp2266mod board today and have the same issue. However, I realized the SS relay is rated 5v input, so I'm wonder if the issue is because it's not a 3v input SS relay?

Hi all,

So spend many hours again troubleshooting. Things I've tried:
Install previous IDE version(from 2018) on new PC, reloaded all driver etc
Used the exact same ESP8266MOD board and drivers as stated in tutorial
Tried previous Brewbench builds ie v4.1.0 all the way to v4.2.0
Used an LED on D1/D2 ports to see if it lights up and communicates

Installed a simple sketch to confirm D1,D2 ports are working via webserver/URL(tested 100%)

Not too sure what else to try other than buying an Arduino Yun.

.... anyone with any ideas? Thanks
