We do this with all of our ceiling fans in bedrooms. Have a 8 KPLs on the wall where a switch was, give it power and leave load disconnected to the keypad. Renders the ON/OFF unavailable as it has nothing to control - however allows you still to use the buttons just the same.
In regards to ‘delay’ - there is a delay, but it’s within a second or two max and I have a wired Bond Bridge Pro. There are times where the light and/or fan will get out of sync with the Bond but haven’t seen that being an issue with the latest firmware released last week/earlier this week. Still watching it. Worse case you can always correct it in the Bond App.
In the bond app click on the bond pro under my bonds: see IMG910
At the bottom hit advanced: see IMG913
local token should be the second field: see IMG912
