Thought I’d add my experience with the triple click WiFi
First the clicks require to be pretty rapid, or they may be interpreted as single ones.
Secondly, initially it wouldn’t work. This was because I already had Wifi set up in wpa_supplicant.conf for auto connection, and this stopped the script from starting the access point correctly. The solution was to clear out the wpa_supplicant.conf network information I had added so that on startup WiFi was NOT automatically connected to my existing wireless hub. Then the triple click got the access point going correctly.
The pisound is a great bit of kit. I’ve just ordered a second one!
