Electronics retailer Best Buy is re-evaluating its partnership with smart home company Vivint, reports Bloomberg. The companies first began working together in May 2017, in a joint attempt to expand sales and reduce some of the issues with smart home setup and use.

Now, Best Buy is apparently unsure whether to continue with the partnership, with the retailer reportedly pulling goods from store shelves — as well as its online store — and removing Vivint employees from the sales floor. This change of heart represents a shift in strategy that could provide some key takeaways for players in the smart home space.

The partnership between Best Buy and Vivint involved bringing knowledgeable smart home employees into Best Buy retail locations to assist customers in evaluating needs and to facilitate installation. Vivint employees took to the sales floor in about 400 Best Buy stores to offer advice on what sorts of hardware and services a customer exploring the smart home might need.
