Making your home smart may be expensive even if you start with small devices. Because it’s a relatively new trend, most smart home gadgets are still quite expensive. You can start with lesser-known brands, but we don’t recommend that as they don’t always last as long. Therefore, their long-term value is lower than popular brands such as Wemo, Philips, Ring, etc. You can begin your smart home for as low as $40 with a smart wall plug, but a full-house setup for an average house of 1,800 sq. ft. costs between $1,000 and $5,000.
