SCOTT WILLIAMS (ID: 000000d82259b593) Voted 5 ★ - Updated 12/05/2022 This made me so happy on discovering it! I am on my first cycle, notifications on and it is repeating the off trigger (appropriate for batt%, but every two minutes). I'm on CromeOS FLEX—updated—running on old DELL Vostro. I'm going to turn off notification. But, ya got any advice?

Nom De Plume (ID: 000000fe2dde62ae) Voted 5 ★ - Updated 07/04/2021 I think as long as you have an outlet that can be directly controlled through IFTTT or indirectly controlled by some other hub or service that has IFTTT support, this extension should work well. Many thanks
