Although the Brilliant Smart App has IFTTT support, the usability of IFTTT is dependant on the product and whether or not it has the IFTTT support.
This is because the products that do work with IFTTT have been registered by Brilliant on the IFTTT platform. So just because the Brilliant Smart App supports IFTTT, it does not mean that other branded products will be able to work on Brilliant Smart AND IFTTT.
It will all depend on whether or not the other brand has registered the product with IFTTT or not.
To find out if the product is registered with IFTTT, Brilliant suggests checking out the product on the brands website - the feature should be listed on the specifications or instructions.
