In India where people buy the devices with lowest possible cost, i have never seen a smart washing machine so far and rarely a smart fridge. The cost of the smart module doesn’t offset the cost of spying yet i guess.
Highly recommended upgrade for anyone with parents. I would now even go to trouble to import a unit with knobs (I asked at a heap of shops before luckily finding someone just beginning with a new line for their shop).
Finding usable devices and buying them for your parents takes a LOT of work, but the work really pays off when you get it right. I also gave them a microwave with knobs.
