Here is the answer from @ady624.
Ok, the reason the piston doesn’t do anything is because your piston has an IF condition that can’t be true when executed by IFTTT. The piston will only run when the routine runs. Do you need the piston to be run by both IFTTT and a routine? If so, consider adding a second trigger for the IFTTT capabiity, with an OR between the two conditions.
Works perfectly this way after editing my pistons. Now I can use one IFTTT Google Assistant applet to execute any piston.
