      @soloam no it should not affect the readings too much if you make holes near the sensor and you have a bit of space in front of it so that the air can flow. For light sensor check BH1750 or MAX44009

      @neverdie Hi, it is not clear from the message, if a movement occurs, will the battery data transmission interval be saved?

      @Nca78 FWIW, I used 1.55mm holes. There may be no perfect diameter since we don't even know for sure yet which lens will turn out best.

      I liked domoticz (was very easy to set up and use). Together with dzVents scripting wasn't that difficult either. But I also had some problem with it lately, so I was actually thinking about switching to openhab (2).

      "So as soon as i've checked this is working as before, i release gerbers, and ask for a mini pcba if people interested." Just in case it was not clear in the other thread, I am If the quote you get for PCBA is reasonable of course, else I'll shift to the power hungry versions with bigger batteries until I feel confident to solder 0603. Or to re-make the design with sized-up components The PIR sensor is pretty cheap, but I guess it's already too high for most breakout board sellers on aliexpress who want to keep the price ultra low. I'm just surprised companies like Adafruit or Sparkfun never did anything low power and just resell the 1$ SR501 at 10$ Only DFRobot claims to have a 15Β΅A PIR which is already a great improvement but I can't get it shipped to Vietnam without shelling out 20$ for express mail Happy new year to you too !

      Here's a random question, has anyone made or considered if possible even, an RFM69 radio version? I'm considering moving to RFM69 from NRF24 due to some range issues.. maybe.. Will need two gateways or something along those lines to keep using these fantastic nodes, have 3. Any thoughts back would be terrific, is there for example some show stopper I'm missing or just a matter of space and creative wiring!?

      @scalz VoalΓ‘! 5.2uA consumption with flash in Ultra Deep Power-Down! Will have to test OTA functionality though (waking up from Ultra Deep Power-Down), but in my experience this is going to be very hard on a coin battery.

      @bjornhallberg can you measure the voltage on your batteries it will be great to know what you're voltage are.
