Can guests use my smart lights without messing up my settings?

Sharing access usually means a guest role, not the admin login, so he can toggle stuff but can’t reset anything. That said, I’d still check what the guest role actually allows before trusting it, since some setups let guests rename devices or remove them. Worth a quick test with his phone before he settles in.

If he only needs the lamps and plugs, a guest invite is the way to go. My in-laws had that for a few months and they could turn things on and off fine, but they couldn’t get into any of the deeper settings. Just double check whether the guest role lets him add new devices, because that part seems to vary a lot between systems.

My sister stayed with us for about three weeks and it was genuinely fine with a limited guest setup. She could flip the kitchen light and the plug for the coffee maker, but nothing deeper than that, and my routines stayed exactly where I left them. I’d just make sure the invite only covers the rooms he actually needs, because scrolling through a whole house of devices gets confusing fast. I once spent ten minutes trying to figure out why a lamp wouldn’t respond before realizing it wasn’t shared with me at all, so yeah, that was fun.

I’d rather set up a separate guest network for the devices than share any kind of account access. My preference is keeping the main setup completely separate from what visitors touch. That way there’s nothing to accidentally reset in the first place.

Sharing through the app’s own guest access has been enough for me, though I only hand out access to the plugs in the living room and leave the rest off the list. The one detail I’d check is that his phone stays logged into his own account, because switching accounts on the same phone is where things get messy.

My cousin stayed with us last summer and I tried the whole guest access thing through the app. It actually worked fine for the week he was here, he could turn the porch light on and off and mess with the living room plug for his phone charger. The one thing that got annoying was he kept adding his own schedules to the plug so my coffee maker started brewing at like 5am on weekends. Nothing broke and my main settings stayed put, but I had to go in and delete his little automations after he left. So it does the job for basic control, but if your brother is the type to poke around in settings you might end up cleaning up after him anyway. Not a huge deal, just something I didn’t think about beforehand. Are you mainly worried about him resetting stuff or just changing the schedules you already have set up?

The guest invite thing in the app is probably the easiest route. My sister had the same worry when her in laws visited and she just shared the lamp and a couple plugs with them, no admin stuff at all. It took her like two minutes to set up 😊

The bigger issue for me would be the automation routines, not the lights themselves. I set up a few things where the porch light comes on at dusk and the coffee maker kicks on before I get up, and anyone poking around in the app can break those without even realizing it. So even if you give someone limited access, I’d check whether they can touch the schedules or scenes, because that’s where the real mess lives. A lamp being turned on at 2am is annoying but fixable. A routine getting deleted is the kind of thing you don’t notice until the next morning when nothing works.

I’ve also found that people who aren’t used to smart home stuff tend to treat the app like a remote and just start tapping around. They don’t mean any harm, they just don’t know what half the buttons do. So whatever access you hand out, it’s worth walking your brother through the two or three things he actually needs and telling him to leave the rest alone. That’s usually enough for a couple of weeks. The controls themselves aren’t complicated, it’s the extra stuff hiding behind them that gets people in trouble.

Sharing just the specific devices is the route I’d take. I did that with a house sitter and it kept the routines untouched since they only had access to the lamps I picked out.

I actually like giving guests a bit more than just the wall switch. When my cousin stayed over, I shared a couple of lamps and a plug with her and she figured it out in a minute without touching my scenes. It was less annoying than me having to turn things on for her every night.
