No, you just need the Amazon Alexa app, then activate the Home Connect dishwasher skill in the respective Alexa skill store and set up the service. You will be notified then via mail and via voice when dishwasher tabs are running low.

To set up smart reorders you make all settings directly in the Amazon Alexa app. Each step is explained here

Please make sure that you have a registered Home Connect account and paired connected dishwasher.

After set up in the Amazon Alexa app, Amazon knows how many dishwasher tabs are left for your Home Connect dishwasher and will remind you via email and voice to reorder tabs through Amazon marketplace when you are running low. You can select your preferred dishwasher tabs from the Amazon marketplace with the same low prices, great selection, and convenient delivery that can be found on the marketplace.

For any issues with Smart Reorder set up via Alexa, please contact the Amazon Customer Service
