Falls du dies noch nicht getan hast, solltest du damit Für die eQ3 Thermostate gibt es auf Github verschiedene Einer der Einträge wird als „CC-RT-BLE“ gelistet. More sophisticated thermostats have replaced the mercury bead with electronics, but the signaling method remains the same, just a simple contact switch.This makes the thermostat the prime target for an aspiring home automation hacker. What I mean is that I have personally shocked the crap out of myself unintentionally fiddling with “power pairs” from a Telco. The actual hardware is a Raspberry Pi 3 B+, booted over PXE, with the official 7 inch touchscreen, mounted on a 3-gang wall box. I’ve just had better luck with the arduino for reliability. The bottom line is that there are usually some alternative and backup operation options for these things as people get angry when their HVAC goes down.I DIY all my home automation gear, but I was reluctant to build my own thermostat because of the consequences of failure (especially where the outside air temp is below 32F for most of the year!). Bei unserem eqiva Thermostat ist ein Adapter dafür beiliegend, der genau passen sollte (eine kleine bebilderte Anleitung liegt ebenfalls bei). [ome.event.ItemCommandEvent] – Item ‚thermostat_wz‘ received command 4.5hab den Fehler gefunden, in Zeile 3 muss man nichts reinkopieren in der PhP.nachdem ich den „doppelten“ Pfad quasi gelöscht habe, lief das Script einwandfrei !

A Raspberry Pi isn’t really an embedded device. Time is very important in how much those stats save you. Alle nötigen eQ-3 Bibliotheken und Voraussetzungen sind auf dem Raspberry Pi erfüllt und wir fangen nun an.Im ersten Schritt kopieren wir das Skript, welches wir gerade getestet haben, in das Apache2 Verzeichnis und benennen es um:Gespeichert wird mit STRG+O, den Editor beenden wir mit STRG+X.http://openhabianpi/eq/php/eq3.php?mac=00:1A:22:0F:C4:DD&temperature=24.0&mode=manualStatt openhabianpi kannst du auch die lokale IP Adresse nehmen. Now have the RPi2, so I have two of them doing nothing. As you all know, however, I have committed to a Partway through the build, I did run into a very strange problem. Nasty stuff very hard to clean off if you don’t have a proper solvent. One thing it does, is “learn” the time constant of the house and heating system, so it doesn’t come on unless it’s needed. This is where one of those ARM cortex boards shine. Now that we have access to that data, what do we do with it? These include a 24 volt AC power wire, leads to switch the heater, air conditioner, and fan, and finally an optional “common” wire, which is often used to power a smart thermostat. “Alright, type ‘sudo furnace.py -settemp 72 -fastheatup'”The pain of running a LEAF router/firewall and then ClarkConnect, still run deep. Also, this data will be important for tuning the thermostat to avoid “short cycles”, when the system doesn’t run long enough to reach full efficiency, but turns on and off several times in short succession.Now that we’ve sorted the connection to the heater, temperature monitoring, and database, it’s time to put them all together. The stakes are much lower when talking about turning a light on/off or unlocking a door (burglary is not really a concern in my small town).I agreed that a microcontroller with some sane defaults in between the PI and the relays to act as a watchdog would be a solid improvement to this projectThere’s a really simple solution here, which most people with vacation homes do anyway: you have a separate, mechanical thermostat for freeze protection, wired in parallel with your fancy-pants unit. Hint: if minimizing standby power is important, you can use a 277V input transformer on 240V, just keep in mind the output voltage would be about 15% lower than rated.Solid state relays would work great for this one line in one line out 0 to 10 volts to control the output. I’ve also turned an arduino into a stat for a garage heater (didnt hook up wifi but did make it bluetooth). For a long time, I wanted to do something with my original RPi B (the one with 256MB) but never found the time.
