            @MisterT Hello again, I noticed that have changed the row “setInterval(function() {” to
            “setTimeout(function() {”

                Hi, I come back again because @sdetweil send me a MMM-Domoticz module. This module works with user and password of domoticz. So if you want see your domoticz devices on your MM you can use this code below.
                Just copy it on text editor and save it as domoticz.js in your MM module folder and in a domoticz folder

                /* global Module */

                	}
                });
                

                After this in your config.js just add for exemple:

                		{
                			module: 'domoticz',
                      			position: 'top_right',
                      			header: 'Températures',
                      				config: {
                            				apiBase: "http://xxx.xxx.x.xx",
                            				apiPort: "xx",
                					apiUser: "xxx",
                					apiPw: "xxxxxx",
                            			sensors: [
                                  			{
                					idx: "183",
                					symbolon: "fa fa-thermometer-half",
                					symboloff: "fa fa-thermometer-half",
                					customTitle: "Cuisine",
                					},
                                  			{
                					idx: "5",
                					symbolon: "fa fa-thermometer-half",
                					symboloff: "fa fa-thermometer-half",
                					customTitle: "Raspberry Domotique",
                					},					
                					]
                					}
                   		},
                

                And it works
                Thanks @sdetweil for your help

                  Hi, everybody
                  I used this old thread because i have a other problem with this module. I update my magic mirror to 2.8 and now this module doesn’t work properly. the error is:

                  Domoticz.js:260 GET http://1xx.1xx1.3x:xxxx/json.htm?username=RmFiaWVu&password=ZmwwNjA2ODVEb21vdGljeg==&type=devices&rid=334 net::ERR_FAILED

                  I think the json request doesn’t match with the good domoticz request

                  http://1xx.1xx1.3x:xxxx/json.htm?username=RmFiaWVu&password=ZmwwNjA2ODVEb21vdGljeg==&type=devices&rid=336

                  ip and port are good but all these after are bad.
                  @sdetweil is the most contributor of this code. have you an idea?
                  i use the same code that the code is above this post

                  thanks for your help
