Thermacell has released a smart mosquito repellent system called Liv. Liv connects multiple repeller units to a smart hub. You can switch the system on and off using the hub, Amazon Alexa or Google Assistant. The Liv+ mobile app also offers control over the repellers. You can turn them on or off from anywhere, set timers and set up push notifications. Using a feature that’s in beta, you’ll be able to monitor the cartridge levels of each device.
Thermacell also offers battery-powered bug repellent units, which says the system isn’t designed to run around the clock. Cartridges should last for a season around eight hours per week for 12 weeks before requiring refills. The repellent uses 5.5% metofluthrin as the active ingredient, and the units heat the cartridges to emit a small amount of fog. says the fog is odorless and provides a 20-foot radius of protection from mosquitoes.
Thermacell had been teasing the system for a while and it’s available to order now. Liv starts at $699 for a pack of three repellers, plus the hub, cables, standard mounts, and ground stakes. Thermacell claims the $799 four-pack will cover 1,260 square feet and the $899 five-pack will cover 1,575 square ft. The system can connect up to five repellers — adding an extra one will run you $150. Refills, meanwhile, cost $120 for a pack of six.
