Do I need an electrician to hardwire a Ring doorbell?

Do you need an electrician to hardwire a Ring doorbell depends on your existing wiring and comfort level with electrical work. If you already have existing low voltage doorbell wiring from previous mechanical doorbell, typically 16 to 24 volt transformer, you can usually hardwire Ring doorbell yourself without electrician, as it is low voltage work similar to installing thermostat, you just turn off power at breaker, connect two low voltage wires to Ring, and mount. Ring includes instructions and tools. However, if you do not have existing doorbell wiring and need to install new transformer and run wires from electrical panel, that involves working with 120 volt household wiring and may require electrician for safety and code compliance. Also if your existing transformer is underpowered, you may need electrician to upgrade to 16V 30VA transformer. For battery models used in wired mode for trickle charging, existing wiring is sufficient. If you are uncomfortable with any electrical work or local codes require licensed electrician for low voltage, hire one, cost typically $100 to $250 for installation. Many homeowners DIY existing wiring replacement in 30 minutes, but new wiring installation is best left to electrician to avoid risk of shock or fire.
