Send a text to node

[skywatch]

@Poupoune1974 I don't know about HA, but in MyController it is easy to forward a payload received from one node to another for display. I use it with a weather forecasting node that sends to the controller and then the value is sent to a node in the bedroom to display on oled screen.

@electrik said in Send a text to node:

Does your sketch fulfill the requirements from this page? https://www.home-assistant.io/integrations/notify.mysensors/

The problem is that I have no notify.mysensors service in HA :

I tried to use the sketch from your page, but could not receive any V_TEXT message.

@skywatch HA might not be the ideal controller to work with mysensors. I ordered an ethernet gateway. Once delivered (6 weeks) I'll hope it will better communicate with mysensors.

@Poupoune1974
I also don't have this service but expected it to show up with this sketch. So that didn't show up, after the sketch presented itself to the gateway?
I don't think another gateway will make a difference.

[Poupoune1974]

@electrik When I replace in the sketch :

request(CHILD_ID, V_TEXT);

With

request(CHILD_ID, V_TEMP);

I could receive a message from HA. Very strange.

With another gateway, an ethernet one, I'd like to do use MQTT communication both ways.

What do the logs say?

[electrik]

I guess you are right and this is not working on HA...

[BearWithBeard]

I wonder - have you specified a protocol version for the MySensors integration in configuration.yaml? Because your HA log hints that you are using an older protocol which doesn't support V_TEXT. It is only available with 2.0 and higher and IIRC the notify service was also introduced with 2.0. The MySensors integration in HA defaults to 1.4 if no version is specified.

mysensors:
  [...]
  version: '2.3'

---

For the record - I just set this up myself and it worked fine. I'm using Home Assistant 0.107.7 (Docker) and MySensors 2.3.2

Relevant code in my sketch:

#define CHILD_ID_TXT 98
MyMessage msgTxt(CHILD_ID_TXT, V_TEXT);
void setup()
{
	send(msgTxt.set("#"));
	wait(1000);
	request(CHILD_ID_TXT, V_TEXT);
}
void presentation()
{
	present(CHILD_ID_TXT, S_INFO);
}
void receive(const MyMessage &msg)
{
	Serial.print("Received a message: ");
	Serial.println(msg.getString());
}

This is the HA log after uploading the new sketch to the node:

[Poupoune1974]

Oh yeeeess !

  version: '2.3'  

did the trick ! Incredible ! I still have no notify.mysensors in the services, but it doesn't matter, I can now send infos to my nodes :

2020-04-17 18:01:35 DEBUG (MainThread) [homeassistant.components.mysensors.device] Entity update: Citerne 1: value_type 47, value = -

Thank you so much !

[Poupoune1974]

And after a node reboot, the notify.mysensors service appears too :

TSF:MSG:SEND,232-232-0-0,s=1,c=1,t=47,pt=0,l=12,sg=0,ft=0,st=OK:It works !!!
