@FailForward @el_jefe I'm interested in building this as well, so far I didn't do anything in that direction lol

But I think anything DIY will be more expensive but also more work than just buying it. I'm particularly worried about power, you probably want solar and battery and it must survive hard frosts as well as extreme summer heat and many heat cycles. Plus, water proofing. It's not easy to diy. As far as wireless goes, if you don't need real time data, it should be doable with something like lora. Wi-fi is probably too power hungry and doesn't pass well through metalized windows. Or, you could use irda if it's just about going through the window

@FailForward @el_jefe for the record I currently monitor outdoor temperature with a simple DS18B20 stuck through a window. It works, but isn't accurate in summer when the whole wall of the building is heated up by sun

@piggo @FailForward @el_jefe we bought this thing and it's actually surviving on few AAA cells for more than a year now

@pony Thanks, good tip. Though at that price range, I can probably already get used [Vantage Vue](https://www.amazon.com/Davis-Instruments-Vantage-Wireless-Sensor/dp/B00481TX32/ref=sr_1_12?crid=1D489X93R10NS&keywords=vantage+pro+2&qid=1667761046&sprefix=vantage+pro+%2Caps%2C1142&sr=8-12), which is like second best after Vantage Pro 2 - the top in this class. I was thinking more at the bottom of the barrel side of things 😄

@piggo @el_jefe

@FailForward @piggo @el_jefe yeah, problem is that when you go much lower, you start really losing features, i absolutely wanted to have the data exported/available on an IP network, that seemed to set the price floor quite high already

@pony
I see. And that thing you mentioned speaks some open protocol? Because if there is some semi-standardised protocol around these things and I know the name of the protocol, maybe it will be easier to scrape the bottom of the barrel 🙂 using Google - it's already 90% of the answer if you know how the thing you are looking for is calles.
@piggo @el_jefe

@FailForward @piggo @el_jefe actually i don't know, i use some website (ecowitt.net) it told me to and it's actually pretty good, so i haven't cared much about alternatives, but i don't think it'd be too difficult to do something else, it doesn't seem that interested in keeping the data from you

@pony Also, actually I really don't want the anemometer (wind sensor) as it is always bulky (though there are static versions using ultrasound sensors) and measures only crap on a balcony. I'd need to put it on the roof to be anyhow useful.

@piggo @el_jefe

@FailForward @piggo @el_jefe yeah wind measurements are garbo (we have it covered with a house on one side), but i don't think that's a large part of the cost anyway

@pony @FailForward @el_jefe wind measurements are actually useful, at least to me, you want to detect abnormally high wind speed to warn you to close windows or clear out stuff on the balcony. wind direction is another thing though yeah thats gonna be utterly useless

@piggo

Just a side note on how to do automated IFTTT style automation on weather if you don't mind that you'll get measurements from somebody else and it might be few kms far away - which for wind is OK. There is [APRS protocol](https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System) which many better weather stations (among other things which speak APRS) speak and there is a whole network of open stations out there. You can have a look e.g., here: https://aprs.fi. Now all those APRS-enabled wx stations report to [CWOP network](https://www.weather.gov/cle/CWOP) and their data can be scraped from findu.com - you just need to look up the correct callsign. For instance this one is in Prague 6 (Studentska ulice): https://www.findu.com/cgi-bin/wxpage.cgi?call=fw4588

I did some things this way in the past. But now I am looking for my own gadget.

@pony @el_jefe

@pony It's bulky, that's my problem. I don't want anything protruding more than 2-3cm from the wall. Firstly, I don't care as I said, secondly, it takes space, fourth, I am sure I would just rip it off or break eventually by some stupid move around, and fifth I live at a place where we do have pretty strong winds few times a year, so if badly installed (which is almost a given with my DYI skills), the thing would just fly off the wall eventually.

@piggo @el_jefe

@FailForward @pony @el_jefe lol reminds me how my bird feeder fell from the 5th floor and hit a bench on the street (bench came out unharmed, the feeder needed some fixing but still works). luckily, nobody was sitting on the bench

@piggo 😄 @pony @el_jefe

@piggo Thanks. Well, no DYI really, that was exactly _not_ the idea. Why I am asking is that for like 10 years I had something similar to this sort of a thing: https://www.amazon.de/-/en/Dostmann-35-1162-54-Wireless-Temperature-Radio-Controlled/dp/B09J8N75S6/ref=sr_1_9?keywords=wetterstation&qid=1667761117&sr=8-9 for like €20-€30 surviving typically about 2+ years on 2 AA batteries. So I thought that maybe as technology advanced, somebody would sell me just that outdoor sensor (as I don't care about that tablet display, or whatever that is). Maybe somebody reverse engineered the protocol such little things speak to the "tablet" and just maybe with a small USB dongle I could receive that stuff indoors. Or so I though... 🤔
