@blacey

You are right.

I don't use eighter NRF24 or RFM69.

I have domoticz server and esp with relay connected only.

All I want to do is switch on or off my relay connected to esp pin from domoticz.

It works for me.

I can see that domoticz sends comands to my ESP.

I can see that receive function on esp side is executed every time I click on domoticz side.

My only problem is "esp restart issue".

I would like to ask domoticz for actual status (is it on or off) in esp setup() function to set my relay connected to esp module.

Now you know my requirements.

1. If you think my code works but I do it in not a proper way please correct me.
2. If you know how to ask domoticz for device actual status please help me.

@blacey

Hi Thank you for hour help.

I do really need to solve it.

I prepared sample as simple as possible:

on ESP:

0;255;3;0;9;Client 0: 0;0;3;0;18;PING
0;255;3;0;9;Client 0: 0;0;3;0;18;PING
0;255;3;0;9;Client 0: 0;0;3;0;18;PING

On domoticz

After restarting ESP (deploy code again)

On ESP:

Then silent

Then After Setup - >Hardware -> Click my device - > Click update

Hi.

Thank you for your reply.

I placed
request(3, V_STATUS);

in setup () and loop()

This code does nothing.

No log messages in domoticz.
No debug messages on esp side.

Another thing:
After ESP restarts it isn't visible in domoticz automically.

To connect it I have to log domoticz console and :

Setup - >Hardware -> Click my device

Then just click update

Just after that I can see on esp side:

0;255;3;0;9;Client 0 connected
0;255;3;0;9;Client 0: 0;0;3;0;2;

Another way is to wait 30 second for domoticz reconnect.

I said that becouse I see that when esp invokes setup() function device is nor connected to device.

Generally speaking I can not see any messages after request(3, V_STATUS);

No receive() execution.

Didn't I miss something ?

HI,

I use esp with relay to switch light.

I integrated my arduino code with domoticz.

Everything works great.

I have only one problem.

After esp restart I want to read actual (just before restart ) status of my light device (was it on or off)

To save epprom I don't want to save device status on esp side.

I know that I can read this status by sending http request : /json.htm?type=devices&rid=3 and parse response.

My question is :
Is there other simple way to read this status ?
