The only smoke/co detector that isn't utter garbage is nest protect. It's the only thing i even consider. I don't know exactly what you require for the 'ecosystem' part but you don't have to pay them anything Ò€¦

Or, crush it up and put it back in spoon with water and remelt it and cook the oil all the way. Now, 8 years later, i smoke 10 a day bc iÒ€ℒm between jobs, which means a lot of free time and boredom at home. I donÒ€ℒt plan to quit in the near future because it helps with my anxiety and i donÒ€ℒt want to Ò€¦
