It's hot here in Germany at the moment, and I've found a new hobby: experimenting with different ways to keep the flat cool. Unfortunately, right now I'm doing that mostly on gut feeling, and I'd like to add some data to the mix so I can pretend that this is Serious Research™.

Does anyone know of some good smart thermometers that I can use both inside and out, and that I can regularly take automatic readings off? My main criteria are roughly:

• Reasonably waterproof and battery-powered - I'd like to put at least one on my balcony which isn't covered, so I want to be confident that it survives out there.
• Relatively cheap - I want around 4-6 different thermometers spread around the inside and outside of the flat to see how the sun's position affects the temperature, and I don't want to spend more than around 100€ on this project in total.
• Scriptable - for the data collection, my plan is to be able to run a script on a spare Raspberry Pi to download all of the data and potentially send alerts when something changes or when it makes sense to start opening doors and windows to cool the flat down.
• Not too complicated - looking around, some thermometers seem to require smart hubs and online accounts and things. Ideally, I can avoid all that - I want something that I can connect to from my home network and download data from as I need.

Right now, I've found a few different smart temperature sensors that I can buy off-the-shelf, but these seem to be on the more complicated end of the spectrum, and require central hubs and uploading all the data to clouds and things like that. Ideally I can avoid that. Alternatively, I have some RPi Pico boards at home, so if I can buy some sensors that I can connect to those, I could get those set up more simply. But with the DIY route, I'm worried about weatherproofing, especially if the temperature sensor needs to remain fairly exposed for an accurate reading.

So: do you have any recommendations either for simple smart sensors that I can buy, or for sensors that I could easily stick to a Pico and leave outside for at least the rest of the summer months?

Has anyone out there hooked HomeAssistant up to a local LLM? I'm very tempted:

• Alexa integrations fail often. HomeAssistant integrations tend to be rock solid.
• Alexa is rule/pattern matching based. LLMs can understand natural language fairly well. The "magical incantations" required by Alexa are awkward.

Other than the software, the device side seems challenging. There are $50 fully-baked POP devices. I'm less sure on the DIY front.

Also, I desperately want my house to speak to me in the voice of the NCC-1701D computer. I've read enough now to know this should be achievable with a modicum of effort via OSS voice cloning tools or training a new model (same difference except "voice cloning" seems to often refer to doing this without training a whole new model?).

Thoughts? Experiences?

I've seen several pages that have led me to conclude this is tenable:

Hey folks - I've been wanting to go whole hog on automating my home, I read through this smart home automation - tips and tricks thread started by @Merry and had a lot of useful information.

Some of the things I took away from it:

• Home assistant is pretty great (if you don't mind tinkering)
• Getting something that will boot back up after a power failure is great
• Use smart plugs / switches vs bulbs
• Maintain it's usefulness if there is an internet outage

Like I mentioned I'd really like for this to be privacy focused and mostly self contained. Sure I'd love to be able to control stuff from my phone while I'm home and also recognize that I'm home or away.

I just am a bit smooth brained when it comes to even seeing "would something like this work with the wiring / circuity that I have in my home already?"

If there are any good guides to follow or really specific advice / steps I could follow to begin this process I'd really appreciate it.

Next week, I will be closing on my first ever home (hello Michigan tilderinos!). One of the projects I want to tackle and work on after I move in is setting up a smart home ecosystem that is sustainable long-term. I saw the open-source Home Assistant but I think I need to do more research on it and find compatible products. For now, my wishlist of projects are:

• Controllable lighting from my phone or computer
• Carbon Monoxide/Natural Gas detection
• Water leak and usage monitoring
• Thermostat

Are there any other use cases that you use home automation for? If you use Home Assistant (or used it in the past), what are some things I should consider? Any products that you bought in the past and regret now?

I've been idly browsing for a home weather station for a while, hoping to contribute to the local sensor network for a region that's got lots of microclimate variation. I saw this one from Seeed Studio today, and was hoping for some reviews and advice. Seeed Studio devices are known for open source software, and I wouldn't mind playing with writing a tie-in for sprinkler system automation so we're not irrigating when it's about to rain. It wouldn't be situated so far from the house that we'd need to use the LoRaWAN feature, though.

Concurrently, we just had an inch of rain dropped on our house in the space of 15 minutes, with winds that were taking down tree branches. The weather report says "light rain", weather stations a mile away continue to indicate that everything is bone dry with quiet air. This rainstorm breaks a nearly month-long drought. I'm finding it nerve-wracking that climate change makes it impossible to use past local weather as a predictor of what to expect for gardening, home maintenance, and outdoor activities, and local weather reports are so inaccurate. So that's (hopefully) where the weather station might come into play.

That being said, any chat about your local conditions and reporting from your station is welcome.
