  • Lithium batteries last 5-10 years, regular 9v alkaline batteries last about 12-18 months. Some sources recommend changing the batteries every 6th month but i personally think that’s a bit excessive.

    I only have a small 2 room apartment so i just got myself a cheap-ish optical smoke detector with a built in lithium battery. The battery should last 10 years which is how long smoke detectors last before they should be replaced.









  • I have a TP-link Tapo D230S1. It comes with an indoor chime that acts like a hub that has an sd-card slot. The hub supports up to 4 compatible cameras and 64 other devices. It’s also pretty affordable and easy to set up. It is however battery only, but it lasts for several months between charges.

    I don’t know of any smart doorbells that can also open doors. Maybe you could use a shelly relay or something similar?
