Automating Mosquito Control with Shelly Outdoor Plug S Gen3

Overview
During warm months, mosquitoes can become a serious nuisance, especially in outdoor spaces like patios, gardens, and balconies. To ensure a peaceful and pest-free environment, many households use electric mosquito diffusers. However, running these devices continuously is not energy-efficient and may result in unnecessary repellent consumption.
This use case demonstrates how the Shelly Outdoor Plug S Gen3 can be used to automate a mosquito diffuser, ensuring it activates only when needed—typically from dusk to dawn—optimizing its performance and reducing waste.
Challenges
Manual Operation: Most mosquito diffusers need to be turned on and off manually, which is inconvenient and easy to forget.
Wasted Resources: Running diffusers during the day wastes repellent when mosquitoes are typically inactive.
Power Inefficiency: Continuous operation leads to unnecessary power consumption.
Pest Discomfort: Missed activation windows can lead to outdoor discomfort from mosquito bites.
