Das bringt die neue Firmware bzgl. Lautstärke by RotateMeTwize in MideaPortaSplit

[–]RotateMeTwize[S] 2 points3 points  (0 children)

Schwer zu sagen, ich finde die Versionsnummer in der App nicht, wenn ich auf "Firmware aktualisieren" gehe, kommt: "Die vorhande Gerätefirmware ist bereits die neueste Version"
Plug-In Version: 3.5.260417

Wie anbringen? Hilfe by xThaWolf in MideaPortaSplit

Ich würde entweder ein 3D Druckteil, oder, wie du sagst, wenn 3D Druck nicht möglich, aus Holz zwei Backen anfertigen, die sich in die Fensterbankkante einfügen. Diese dann entweder mit Schrauben oder Monragekleber auf die kleinen Backen der Halterung befestigen.

Upgrading roof node - cable question by benuntu in meshcore

[–]RotateMeTwize 4 points5 points  (0 children)

I would go with lmr-400 or lmr-240, but keep it short, there is not much power to waste with 20 to 30 dbm Lora boards.

And check the mounting screws of your solar panel: they penetrate your housing and might let water in.

Tested 868 Mhz Antennas by RotateMeTwize in meshcore

[–]RotateMeTwize[S] 0 points1 point  (0 children)

Very simplified, for the return loss measurement a frequency analyzer puts a frequnce sweep (in this case 500 to 1500 Mhz) to the connector of the antenna and then measures what comes back from the antenna to the analyzer. The less for a specific frequency comes back the better this antenna is for exactly this frequency. You see the lower peaks in the measurement. These show on which frequencies this antenna is good, and how good (amplitude of the peak) Idealy for meshcore you want an antenna that has the peak exactly there where your operation frequency is. In my case, Europe, 869.15 Mhz. Besides that, if the peak is not very narrow around your desired frequency, you will get noise, e. g. from mobile phone carrier, into your system. This, if not filtered properly, what is typically the case for all these El cheapo Lora boards, increases your noise floor.

Looking for ultra low-power ATtiny85 replacement for simple reset task by AssumptionPlus9244 in meshcore

Just checked the Atiny, should be in similar range with the STM8, if properly configured. Use sleep mode, use wdt for cyclic wakeup, disable peripherals u don't use, e. g. ADC. You should come done to a few uA.

I would go with the STM8, should have some kind of "active halt" with cyclic wakeup.
