My Project

Thanks for posting! Sounds at least a little similar to the system recently described by Andreas Spiess, which also uses espnow as well as repeaters to backhaul packets to a central processing station: https://www.youtube.com/watch?v=6JI5wZABWmA

Success! Treating the nRF52805 like an nRF52810 and uploading to it from Segger Embedded Studio's IDE using Nordic's nRF52 SDK's PCA10040e board definition, then pin P.18 blinks using the same sketch that blinked P.18 on the nRF52832. I'm reporting back with this good news, because I haven't seen it tried or documented anywhere before. At least for this modest first attempt, this simple spoof works! At $2.50 each, these tiny nRF52805 modules with their trace antennas are a good value. By the way, the compiler that's built into Segger Embedded Systems is super fast compared to gcc.

@mschro1 I really got inspired. I ordered a flowmeter and the plumbing to check it out. I wrote code that actually works. The 5V from the Arduino can drive the sensor. I'll be putting it all together this weekend. My goal is to determine how much water I'm extracting from the seep on my property. I'm having fun :)

@yoshi824 Most of us have been where you are now! I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn. If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.

@davedeluxe I ordered the PCB from JLCPCB. The design is available here: https://oshwlab.com/jamozu/multi_project_copy_copy_copy_copy_copy_copy And the sketch is available here: https://github.com/jamozu/multisensor

@clivec If you look in the MySensors code, wifi is not an option for the radio transport. You'd have to somehow write your own deal for that, and it would likely get really involved. ESP32 is supported for a gateway, where the wifi is the backhaul transport, effectively, but you would need a separate radio for the MySensors side of things. To use an ESP32 on its own, without a separate radio, you might look into something like https://esphome.io/ This does not allow for interaction with MySensors directly, though. What is your ultimate plan? An ESP32 is very power hungry when on wifi, so it wouldn't work as a battery-powered device very well. They're pretty cheap, and easy to get a hold of, so if you have them plugged into mains power then you could use them alongside a MySensors network. Maybe with something like Home Assistant controlling both and providing a link from one to the other if needed? Maybe you haven't been getting much interaction here because it doesn't fit very well with MySensors. I've seen your previous posts, but since I haven't tried to connect any ESP32 devices to the network, I didn't have any input for you. (I prefer my backhaul to be wired, so the ESP32 wifi was a negative, in my book.) I mean, I have nothing against ESP32 for other things, but for me it has no place in the MySensors network at all.

And here's the completed unit I have not really tested the range yet , but should be good , the receiver units (telemetry units) can work in latching mode and in push button mode easy I am pretty sure this setup will last longer than fibrio key fob , easy to pair receiver with key fob I have 3 key fobs ,, yes why ??? well they will break and I rather purchase few ,for an investment for the future Maybe some can help me with other project the stamp m5 pico trying to program it is a standard switch node https://forum.mysensors.org/topic/11886/and-for-my-next-trick-project-i-mean-m5stamp-pico-any-body-playing-with-these-yet-battery-operated-mp3-unit/2?_=1642356371902 [image: 1642121345885-completed-resized.jpg]

@mrmuszynski Hi, there are some setters for message payload types but none for type String, see: Message manipulation. You need to convert the resulting String into const char* like this: send(msg.set(("string " + String(expectedScratchpadValues)).c_str())); But in general I would try to avoid usage of the String data type, especially for the use case in your code example. You could use e.g.: char str[80]; sprintf(str, "string %d", expectedScratchpadValues); send(msg.set(str)); For Arduino String read more e.g. here: The Evils of Arduino Strings HTH

@NeverDie I used ethernet cable as an audio cable so later I can use those 6 unused pins something else.

Hello, I you are interested in the full integration with Brink Renovent HR, please have a look here: https://github.com/raf1000/brink_openhab/blob/main/README.md The integration is with openhab but similar one can be done with home assistant I suppose (mqtt) It is tested with Brink Renovent HR, but Brink Renovent Excellent has the opentherm protocol available as well...

Merry x-mas (late)

Where can you download these apk now?

@Kai-Bepperling is this product for sale ?

@ncollins Are you currently working with any NRF5x? Do you have a working motion/contact sketch for the NRF52?

Thanks! I'll check it out. Brendan
