@GaryStofer said in Error sending switch command, check device/hardware !:
I cant change the Controller to anything else , not that I think is controller related -- The customer is happy with Domo and has many man hours invested in scripts and interfacing.
Sure, I'm happy with Domoticz too it wasn't me suggesting you to move to other controller. I suggested just to keep Domoticz, just upgrade it new version
. But I can understand the upgrade may be difficult, if customer has developed many stuff around currently installed version and most of them is working fine...
