💬 Connecting the Radio
-
@maghac yes, an spi flash chip. It is not a bad solution since the firmware is transferred during normal node operation and if it fails nothing bad happens.
@maghac - EasyPCB rev 10 will probably include spi flash ;)
-
It might be an idea for the "connecting the radio" page on MySensors to point to these handy boards:
https://www.aliexpress.com/item/Free-shipping-Nano-328P-IO-wireless-sensor-expansion-board-for-XBEE-and-NRF24L01-Socket-for-arduino/32298692903.htmlThen people have to just plug in the NRF24 boards. And it also makes it much easier to connect lots of sensors. I wish I had known about these boards earlier, it would have saved me a lot of time.

Just noticed, that MySensors 2.2 changed default RF24 CS pin on Mega2560 from pin 10 to pin 53 (SS) :/ I could not find any reference to the change from 2.2 change log nor from pull request (722)... No wonder RF24 worked with 2.1.1 but not with 2.2 on M2560.
Contrary to instruction above, I wanted to continue with old pins (same as on Uno) and set the pins explicitly to MY_RF24_CE_PIN=9 & MY_RF24_CS_PIN=10. Now transport seems quite good (with combined HW and SW ack, static GW address, no routers) :) -

Looks like the change was introduced in commit b132a8a81e2ba6c81bcc6e2afce7513cdddbe193. I have added a message to the release notes.

@mfalkvidd: Yes that's the page I'm referring to.

While you're at it: maybe tell people about the NRF52 option?
-
@alowhum thanks. That does indeed look lika nifty solution. I'll add it.
For the nrf5x, I don't know which boards are user-friendly, and I haven't understood if MySensors nrf5x support is "production ready" yet or if it requires people to tweak or otherwise do special stuff to get a node working. I don't think I have seen anyone building nrf5x MySensors nodes yet.
-
Lots of people have I think, check the NRF5 thread. I built my own first one this week (BME280 sensor). It rocks.
- Arduino with built in NRF24 for $3.
- The size of a postage stamp.
- Powerful enough to use the simple encryption functionality.
- Antenna socket: just plug in antenna for more range.

My first post at mysensors.org. Sounds like a great tool. Tried to set up an MQTT Gateway with Hardware as described above, ESP8266 and RFM69W with 868 MHz, to connect some Technoline TX29DTH-IT temperature and humidity sensors, without success. ES8266 is working , connects with my wifi network and also connects to my mosquitto server. But I do not get any connection from RFM to technoline. Is there anyone out there who was able to get this running?

@42isjustanumber welcome to the forum!
MySensors uses its own protocol and is therefore not compatible with the TX29DTH-IT.
You can however build your own temperature and humidity sensors from examples on this website and start expanding your network from there! -
@Yveaux: thanks for the information. I thought it's much easier. I heard about LaCrosse Gateway which seems to be able to connect to Technoline temperature and humidity sensors with Nodemcu and RFM69 hardware and connect it to FHEM. I wanted to have a more general approach and just forward data from technoline sensors via MQTT. But if this is a totally different protocol I'll have to look for another solution.
-
That was my misunderstanding. I thought with the hardware and settings mentioned above, I would be able to read the data from any Technoline sensor. There's a YouTube video from Miika Kurkela explaining how to interpret the data from these sensors. But to be honest, I only unterstand half of it.
