I will post my thoughts over the weekend. I have no home automation or monitoring presently, and don’t have anything but a smart meter that I could monitor. Most of my big stuff is Natural Gas, with the exception of the Air conditioning. As such I just power fridges, freezers, lights and computers. Lights are all LED so they aren’t very big. Fridges/freezers and computers split the rest of the usage, but they all use power when they use power, so managing the AC would be a big way to keep my average cost per kwh down.
My name is Jaap and I’m from Amsterdam, NL.
I just connected a HestiaPi touch to the central heating in our makerspace.
Since the makerspace is located in an old building without much isolation, it’s nice to be able to adjust the temperature from home before going there. I was about to design something (arduino or pi-based) myself but then I discovered the HestiaPi.
Fortunately I looked at the PCB before plugging it in, because the central heating system would not have survived 220V! I was not expecting that as the default output…
Cutting one pcb powerline and adding a wire solved the problem.
Still have to figure out all how all the OpenHAB stuff works, my wishlist for now is:
- temperature statistics (maybe with extra sensors to monitor remote corners of the space and outside temp)
- simple and safe remote access for all makerspace users
- calendar / scheduling, possibly linked to the existing makerspace calendar
- interaction with the burglar alarm, as a way of knowing when there are people in the space
I’m pretty sure most of this can already be done with the existing software, I just need to read the fine manual…

Welcome! Make yourself at home, we’re a small community but a friendly one 
Still have to figure out all how all the OpenHAB stuff works, my wishlist for now is:
I’m not so hot on electronics, but OpenHAB I can do. Shout out if I can help!
- temperature statistics (maybe with extra sensors to monitor remote corners of the space and outside temp)
Something like this?
I can probably help there… Although I have a Hestia Classic (so my Openhab is separate) the details will be similar.
- simple and safe remote access for all makerspace users
What did you have in mind? If you have some server which is web-facing then I guess an Apache/Nginx proxy vhost with basic auth would do?
- calendar / scheduling, possibly linked to the existing makerspace calendar
I’ll let @HestiaPi handle that one
- interaction with the burglar alarm, as a way of knowing when there are people in the space
Depends what the alarm speaks. OpenHAB has a huge stack of protocols and such that can be used as triggers or presence detectors, so you need to know which one(s) to look at.

Actually, I’ll leave this here …

Welcome Jaap! 
We hope you like your new HestiaPi!
Well myopenhab.org may be just right for you with the minimal effort. Then again, it is an external server you don’t own.
Greg’s suggestion about caldav is your best option right now I think. If you search around OH forums you will see some workarounds (while the official native scheduling is being developed) but may require more time from you depending your familiarity.
Not sure if this is for actual security or simply informative… For the latter a simple bash script that detects ping-able devices on the WiFi network may be enough. Share your thoughts 
Heya! I’m a new user from Italy and I’m currently hacking on my great HestiaPi.
My evil plan: integrate HestiaPi with open source thermostatic valves and slightly modify my HestiaPi touch to work without Wifi and be powered through PoE. Bold plan? 
Hi everyone. My name is Fernando and I love doing projects like this one, I program in python, java, and a few other languages. I am not willing to shell out 300 bucks for the nest since I have two HVAC units one for the lower floor and one for the top floor. It was strange to see water heating for the thermostat lol but I guess other places they do that. Here in the US the water has its own boiler that doesn’t get fiddled with at all.
Anyways It is good to be part of a great open source project! I love the hexagonal case by the way.
Hello!
I’m new here and am planning to work on the US HVAC version of the HestiaPi Touch.
I’m an electrical engineer who has barely any free time to spare but always find a way to spend it on electronic/computer/automotive crap. I have always liked DIY projects, especially raspberry pi ones, and hope to see this one prosper into something more well-known.

Hi my name is Tim ,
I discovered Hestiapi through @gwmngilfen Greg on Mastodon .
I’m Extremely interested in this project as I’m about to have Gas central heating installed and this is something I would like to incorporate into my Home automation setup .

My name’s Sam, and I’m in the US (in Minnesota). We bought our first house last year and have been gradually updating it to more modern standards. I’ve started running cat-6, we’ve repaired and repainted our deck, and soon we’ll be wanting to replace the old, crusty thermostat with something smarter.
I found HestiaPi by searching for “open source smart thermostat” on google. I definitely didn’t want to buy some closed source thing that I’d be relying on large corporations for - I trust them to be neither good nor supportive. I joined because, while I’m not yet ready to set HestiaPi up (we have a four-wire cable, so I’m hoping to rewire with a five wire cable first … although it’s tempting to get one of those four-to-five wire adapters instead), I’ve got some questions to work through and whatnot.
I’m https://github.com/nelsam - typically a go programmer (also elm when I write web UIs), but generally good at distributed systems and chaos testing.
I’m also a nerd in general - miniature tabletop gaming, craft beer and cocktails, comic books, and video games are all passions of mine.
Welcome to the club @valczir !
This is the best place (erm… in a new thread) to ask all your questions and find out what HestiaPi can and cannot do

hi Arden here
found this while Googling around
have caught the diy home auto bug
already have an existing openhab pi with mysensors
in the process of building some motorized curtains using 3d printed parts
Please elaborate
Does your mechanism allow “manual” control of the curtains, aka “by hand” ?
in still playing around with the config
idea is to set limits and then define it as “dimmer” in openhab then can say set to say 50% ect
Was more curious about the mechanical aspect of it and if it can support what I described 
it should be easy to add an open close button
been able to pull the curtains would cause problems due to lost position
Hi everyone,
My name is Esther and I’m from the Netherlands. Data Scientist by day, tinkerer by night. I’m diving into HestiaPi as a kick start project to overhaul my house with home automation. So far I’ve worked on projects on the wearables spectrum, so I look forward to connecting with you all over home automation!
Cheers,
Esther
I suppose I should chime in. I’m Rich and live in Colorado. I’m a long time user and supporter of openHAB (I’m @rlkoshak over on the openHAB forums). I’m a computer security engineer by trade but have had openHAB and home automation as a hobby for around five years now. I don’t think it would be too arrogant to call myself an openHAB expert, at least from the user’s side, so if there is any general openHAB question that George can’t answer I’m certain I can.
I learned about HestiaPi when it was announced on the openHAB forums which was right around the time Google announced the end of the Works with Nest API. I figured what the heck and decided to replace my Nest with this one which I can tinker with. I’ve a number of HVAC behaviors I currently implement on my main openHAB that would better be implemented on the thermostat itself (e.g. turn on the fan when the top floor is warmer than the basement in the summer).
But before I do that, I noticed that this little guy takes a really long time to boot so I thought I’d see if I could apply my openHAB expertise and see what I can do to improve that. I’ve a couple of PRs already submitted that brings it down to ten minutes from white screen to operational, at least for me, others will need to test it to verify. Next is to add in hysteresis for the heater, cooler, and humidifier/dehumidifier and then to tackle scheduling which has been mentioned on this thread. My hope is to make everything either a PR or a tutorial posted to the wiki or this forum.
