I'm wondering if the device limitation for some of these Alexa ESP emulators is due to the authors are using the GPIO pins.

Since my ESP-01 is limited to 2 pins (unless I do some extra coding) I would be limited to two devices using the pins.

However if the limitation is not related to the number of available pins but overall calls that that too is a bummer.

I currently have Alexa setup to control 3 X10 devices in HG via my ESP-01, none are using GPIO pins.
I don't wish to code in more untill I've had a chance to test the responce verses my HA-Bridge setup.
I'm sure A Wemos D1 will perform better then this ESP-01.
In any case my ESP-01 will make a nice "Lite HG Client" with or with out Alexa.
