Hardware

That's why I bought shielded modules

@Technovation Welcome to the MySensors forum! This is an awesome first post! :+1: Hope to see a lot more in the future! :yum:

@Yveaux Works perfect now, thanks. Now I just need to research calling this as a transaction. Just brainstorming a bit, I will most likely have a function written to grab the value from the sensorand begin and end the transaction there, but since I have never worked with transactions, I will need to research how to write the code to do that.

@zboblamont Thanks for the advice. I have been looking for a circuit diagram of the sensor to determine how adjusting it could change the beam. I would love if the beam was not as wide.

Is any of this code archived someplace? Any direction to get started? I want to shut off my tv via Vera Edge.

@Gus8 Do you either have a pull-up resistor in place, 4k7 to 10k, or possibly have the internal pull-up resistors enabled for the data line that you have it connected to?

@zboblamont It may be a board that they use for a few different sensors. They make these as boards with the necessary pull-up resistors and things to minimize the need for extra components when breadboarding a circuit for testing or other purposes. You could potentially unsolder the DHT22/AM2302 from the board if it didn't fit your design. You would just then have to remember to include the pull-up in your design.

@NeverDie said in Any users of LiFePO4 batteries ?: @Nca78 No links. Just the usual "burst into flames" safety concerns. I see, then I'm not too worried. Soshine seems to sell a lot of batteries and I didn't see any report of explosions or related things. And when charged and discharged quickly (for capacity testing) they seem to stay much cooler than even my brand name 18650 cells. The guy from Lygte has tested a bunch of batteries and results are good for all the soshine, and it means capacity measurement on my charger is not bad, I measured 600mAh for the LiFePO4 AA and he has 550. Every other battery brand that is available on AliExpress and he tested has completely bullshit claims about capacity. What's worrying is they also lie about having protections, and some brands like TrustFire rewrap some old batteries from powerpacks and hide marks/rust/... with new tops and bottoms, this is mainly the case for 18650. Old rusty batteries without protection, and all different despite behind inside the same wraps :o Page for small batteries : http://lygte-info.dk/review/batteries2012/CommonSmallIndividualTest UK.html

@gohan said in Wemos XI: So is this board really not good for battery powered sensors? IMHO not at the moment and I don't think it will change soon as doc from wemos or the chip manufacturer are still very poor. I fail to see the interest of the this board compared to a pro mini clone, except saving 0.5$. There's no obvious way to make it really low power and you have a different pinout so you can't use any of the existing PCBs.

@mfalkvidd I can have it output in either 12V or 24V - my choice. I have various SRD-12VDC-SL-C octocoupler relays, but I have no idea how to set it up as a sensor instead of an actuator. :( @gohan see my reply to mfalkvidd I had a look at the Power Meter Pulse Sensor but I am clueless on how to transfer it to my components. Thanks again for taking the time to help.

You can use only 2 interrupts on pin 2 and 3, calling 4 sleep functions is useless

well yes, that will do the same, but i think that using for example MCP1640C (you can check the example project here https://www.openhardware.io/view/279/Adjustable-Boost-Converter-with-Pass-Through) will result in simpler schematic :)

@mfalkvidd Thank you. I was more concerned about VIN 5V I think in my IOT only few rfm69hcw would draw 130mA and maybe nrf24l01+ pa lna, but it has a different power feed

@mfalkvidd > Seems like leds are only able to convert about 10% though. 10% !! What a bummer. For being so efficient, can you imaging how low power the next step in lighting will be? Time to invent the next version of LED.:sun_with_face:

I'm using these as a reset button on some wireless solar nodes: https://www.aliexpress.com/item/10Pcs-SMT-3-6-2-5-MM-Tactile-Tact-Push-Button-Micro-Switch-Momentary-2-Pins/32648604590.html?spm=2114.13010608.0.0.gOyHck They have a nice solid feel to them.

For anyone who is interested in this topic, I posted some comments about the am612 on this other thread: https://forum.mysensors.org/topic/5986/pir-am312-412-612 It may have some relevance to the am312.

Oh thanks everybody, I'll try it today.
