Send a text to node

[Poupoune1974]

I have about 20 mysensors’s node, who send their values to HA, through a USB gateway.
This way is OK.

But now, I need to send infos from HA to my nodes (for LCD displaying, etc.)
I tried with notify.mysensors, but I cannot get it to work : there is no sevice called like that.
And it seems to be abandonned :

https://www.home-assistant.io/integrations/notify.mysensors/
https://forum.mysensors.org/topic/10488/homeassistant-mysensors-notify-does-nothing-alternatives/7

Does someone have a workaround or knows how to integrate the that service in HA ?

I'm using node red for this purpose. This makes it easy to send data to nodes, without even following the integration guidelines for HA.

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

@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:

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?

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:

The notify.mysensors service appeared right after presenting the new V_TEXT/S_INFO child. Sending custom messages from there works aswell.

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 :
