Re: [weewx-user] Best Davis station for my buck, and purpose?
I've fiddled with all the pieces individually on raspi Used rtl_433 to listen to Acurite and have done rtldavis+weewx for the VP2 as well as Gary's gw1000+weewx for ecowitt. All worked fine for me, so cobbling them together would seem to be reasonable if you like that many rtl-sdr dongles. Seems like a perfect thing to do with docker on a pi4 or small intel box since individually they're lightweight. - one docker instance for each radio and weewx instance - one for a MQTT broker - one for Home Assistant to build a dashboard and/or do automation - a small Kindle Fire for an always-on display FWIW - that's how I do my automation currently, including HA reading my Zwave door/window sensors. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

Scaled Instruments is a great suggestion. I just ordered a Davis 6312 console, he has a few left.

As this is how weewx users can get data, I think limited discussion is reasonably OT.. I am running 4 rtl-sdr dongles and am part of rtl_433 upstream. My view is that to get reliable data, you need to have a receiver on each frequency. I have one on 433.92 for Acurite devices, one on 915 MHz for Ecowitt, one on 315 for TPMS (not weather) and a second on 433.92 for TPMS (different location) but also picks up Acurite. rtl_433 does not receive Davis but rtldavis does. However, AIUI Davis transmitters change frequency every transmission and the receiver knows the pattern and changes proaactively to match, once synchronized. So I expect that while it might be possible to make this work on an ESP (vs a "real computer" with an SDR dongle), it is likely to take one receiver per frequency, where Davis's hop pattern counts as a frequency separately from normal 915. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

Regarding "phone home" I plan to experiment with such devices next year https://www.rtl-sdr.com/rtl_433-ported-to-esp32-microcontrollers-with-cc1101-or-sx127x-transceiver-chips/ My goal is to capture all the broadcasted values from my devices, cache them locally, publish them in realtime using MQTT and make cached values available using REST. In other words: build my own GW. I didn't find any projects like that so far. In theory, it should be possible to combine any wireless sensor which is broadcasting unencrypted values, into one such gateway. My resources are very limited, so we'll see. I'm still hoping to find something out there, that solved this already in the one or the other way and made it available for the public. It would be more than nice, if one could use his Davis UV/radiation sensor, his ecowitt rain gauge and LaCrosse anemometer to be read by a single device. Sorry for OT! vince schrieb am Dienstag, 19.

Re: [weewx-user] Best Davis station for my buck, and purpose?
Too many options but there are 'years' of recommendations over in https://www.wxforum.net/index.php?board=71.0 if you poke around there. For a $300-800 price range you will likely not do better than Davis but the crazy expensive part is getting it online so you can hook it into weewx. You also need to consider if you want a LAN-only solution like most old-school folks do. These days most vendors (Ecowitt) require a gateway that phones home to China occasionally for software updates or watchdog heartbeat checks. Other vendors have moved to a 'feed THEIR site' model that you can't turn off (WeatherFlow, Davis with the new console) that many people are starting to object to. For a LAN-only solution you can get there for about $600 if you go Davis Vue sensor suite, a old-style Davis console, and their absurdly expensive logger. That would be plug+play with no vendor accounts etc. needed. If you go with a Meteo-Pi third party logger you're down in the $550 range or so although the Meteo-Pi has some setup needs. Both scientificsales and scaledinstruments have been great vendors for Davis gear historically so compare the two re: price. Reason I mention Davis is their gear seems to last forever. If you bump up your budget and go VP2 the pieces of the puzzle are pretty replaceable as things age and stuff eventually fails, but it's really big in size. For integrating other stuff, I use MQTT to feed Home Assistant and display on a 8" Kindle Fire tablet running free FullyKioskBrowser. Works great. Since you have inside sensors you probably don't need the inside console unless you really wanted one, so you could get there with a Vue sensor suite ($300), a Meteo-Pi ($85), and a Kindle Fire when you catch it on sale ($40). That plus whatever gear you'd need to run weewx + HomeAssistant + MQTT and the time value of your labor and blood pressure. Once you have it set up, it would run hands-off. A pi4 would be plenty good enough to run all that stuff, although around here I offloaded HomeAssistant+ZWave+MQTT to a little i3 linux box (under Docker) for performance reasons. I could likely fit everything on the pi4 if needed without too much worrying other than trying to minimize SD writes. Careful with solutions that have the new Davis console. There's no programming API there so you'd need to have the console feed Davis (ET phone home) and then your weewx setup would need to 'query' Davis for your data.

Re: [weewx-user] Best Davis station for my buck, and purpose?
If you're intending on new, check with Scaled Instruments: https://www.scaledinstruments.com for pricing. It's likely he can assemble a package that includes the ISS and the classic 6312 console (the new 6313 console cannot be connected to directly by WeeWX, as I understand it and has a lot of issues to be resolved). You would almost certainly want a third party logger so you don't pay for the Davis software which you'd almost certainly never use, and the Davis logger that only comes with the software. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.

[weewx-user] Best Davis station for my buck, and purpose?
I recently moved and made the conscious choice to leave my Accurite 7 in one behind, intending on a major upgrade now that I'm a homeowner and not renter. Now, I'm overwhelmed by choice. For my purposes, I'm looking for good quality and accuracy, setting my weather website back up, contributing to NOAA, and integrating my homemade temp/humidity/pressure sensors within my house. I'm not trying to provide data for flight/navigation etc., so I'm somewhat in the middle. I want a great system, but not a purely professional system either. Blah, blah, blah... what recommendations do you have for best bang for the buck in that kind of use case? My wallet wants to open around 300 dollars, but will have to slam shut again at about 800. I THINK I want Davis, but am quite willing to look at any others some of you might suggest.
