@mfalkvidd Than I'll order a first prototype if this version. I might even swap the buck converter for an AMS11173V. I always thought it would draw much more current when sending.

My production Gateway is still on a breadboard with a normal NRF24L01+ radio - so not the long range. After 11 years it's time to get rid of that breadboard setup- as it's collecting dust - and make a final PCB for it, so that I can put it in a decent housing. Also a good moment to upgrade from MySensors 2.0.0 to the latest release as I haven't upgraded that Gateway for years.

My plan is to power the gateway from the barrel jack on the Arduino UNO and I also want to replace that normal NRF24L01 with a PAN LNA version. Now I know that extending the range consumes a lot of power. That's why I wanna power the Arduino from the power jack as it can handle 2 Amps. And then use a buck converter that grabs it's power from the VIN pin on the Arduino, to lower the voltage to 3.3V for the radio.

Well that is the plan at least. The official documentation says that you can provide power through the barrel and use the USB.

Here's the schematic for my Uno shield
:

My question is: How much current does the NRF24L01 PAN LNA draw when set to RF24_PA_HIGH?

For now it remains Work In Progress xd

@KevinT Any idea how much current that sensor is drawing? I came across one circuit that consumes 1 micro amps regardless if the tank is empty or full. Still struggling to get it to work. But that's my low knowledge of electronics

@nagelc I'm thinking about making some kind of shelves with PJON built in. The shelves will have a wireless charger and with PJON I can communicate "Wireless". So on that shelf I can put some things like small candles, maybe a modified humidifier.

Things like that xd

@tekka Thank you

@mfalkvidd Is the PJON support in current release? Pjon is something that is on my wish list

You don't check for which sensor the message is send - message.getSensor() - and in both cases you set the relays both on Like Skywatch said.

So you could do something like:

if ( message.type == V_STATUS ) { // check if GW send a status change
     if ( message.getSensor() == sensor 1 ) {
          // handles sensor 1
     }
     else if ( message.getSensor() == sensor 2 ) {
          // handles sensor 1
     }
     ...
    etc
}

@KevinT That is a great project. How do you measure the water level?

I did a grep on the source code and found this snipper

#if defined(MY_GATEWAY_ESP8266) || defined(MY_GATEWAY_ESP32)
	// Turn off access point
	WiFi.mode(WIFI_STA);
#if defined(MY_GATEWAY_ESP8266)
	WiFi.hostname(MY_HOSTNAME);
#elif defined(MY_GATEWAY_ESP32)
	WiFi.setHostname(MY_HOSTNAME);
#endif
#if defined(MY_IP_ADDRESS)
	WiFi.config(_MQTT_clientIp, _gatewayIp, _subnetIp);
#endif /* End of MY_IP_ADDRESS */
	(void)WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD, 0, MY_WIFI_BSSID);
#endif

MySensors uses the standard ESP libraries for this. So I expect it to work. But you need to provide at least a bit of source code. Right now it's hard to answer your question. Regarding to MySensors:

• A HTTP hostname can only be set for Gateways that either use Wifi or Ethernet
• For nodes you can provide a sketchname and that will be seen in your controller.

Regarding to static non static IP addresses. I prefer to use DHCP and set that device in my router as a static IP. There I also give it another hostname. So that in case I have to replace my Gateway I can do it all in the router.

Hope this helps. But please provide more info on what you're trying to achieve

@hlehoux As I understand the limitation of the packet size is by the NRF radio. Maybe stop supporting NRF, so that we can get a bit bigger packet size. That would help my current project where I'm using MySensors as a transport layer. I know that is easier with wifi. But I want to use mysensors.

Never mind: If I hexify everything, I can squeeze in all I need so far.
