Start or not...?

 Sorry guys, 
 exist a wireless sensor (WiFi, bluetooth,etc…) that transmits the temperature to the Raspberry?
 Maybe there is some MM module that manages the communication …Thanks 
 Good night! :sleeping_face:

 @egnos said in Start or not...?: exist a wireless sensor (WiFi, bluetooth,etc…) that transmits the temperature to the Raspberry? Pi 3B has WiFi and bluetooth built-in. Pi 2B needs a USB dongle, but they’re not expensive. If you want to display your house temperature, you need a smart thermostat like a Nest or an Ecobee. There exists a module for Nest, but I don’t know about Ecobee. Maybe you would relay that through Home Assistant? If you want to display the weather outside, there are a bunch of weather modules available. I’m sure will suit your needs well.

 I use cheap Xiaomi sensors in all rooms in my house, displayed on MM.

 If you want to display the weather outside, there are a bunch of weather modules available. I’m sure will suit your needs well.I would like to display the “real” outdoor temperature, if possible using a temperature sensor. 
 I would like the real external and internal temperature (the internal one I will take from a smart thermostat) always be visible on my MM.
 The temperatures acquired by the various modules are estimates…correct?@peter said in Start or not...?: I use cheap Xiaomi sensors in all rooms in my house, displayed on MM. 
 PeterWhich module for MM do you use? 
 Which xiaomi sensor do you use?I have another questions: - 
I bought the “Sonoff 4ch pro r2” but I do not understand how to make the Sonoff work together with the physical switch. 
 Example:
 STEP 1: I turn on the light 1 with Sonoff
 STEP 2: I turn off the light 1 from the physical switch
 STEP 3: I turn on the light 1 with Sonoff
 It’s possible?
- 
Is it possible to receive feedback from the “Sonoff”? 
 Example: I would like to know if the house gate is open or closed or if the garden light is on, etc …
- 
the “Sonoff 4ch pro r2” has a 433Mhz receiver (I think it is used to open the automatic gates …) and I would like to use it using a 433Mhz transmitter. 
 Are there transmitters with 433Mhz for Raspberry?
 Have you tested someone?
 Could I use GA to open the gate at home?
 Thank you for your precious help!!

 Hello everyone and happy new year! 
 I returned the “Sonoff 4ch pro r2” because it was not for me!During the Christmas holidays I started the installation of the Magic Mirror with all its modules. 
 These days I’m trying to install the module MMM-Assistantmk2 but I did not understand how to activate the assistant with my voice.
 In the configuration of MMM-Assistantmk2 module I did not find a way to insert a watchword to wake up the Assistant.Can you help me? 
 Do you need to install modules like “MMM-Hotword” and “MMM-NotificationTrigger”?Thanks guys. 
- 
 @egnos 
 MMM-Hotwordis needed if you want to activate it with voice hotword.

 @sean said in Start or not...?: @egnos 
 MMM-Hotwordis needed if you want to activate it with voice hotword.Thanks Sean! 
 So if I only install the module “MMM-assistantmk2” how can I use it?
 So if I only install the module “MMM-assistantmk2” I can not do anything … correct?
- 
 @egnos 
 You can activate it with touching or clicking icon (If you have a touchable/clickable input method like touchscreen or mouse).
 Or You might have another input method like H/W button, or anything else. You can activate with other module which can emit notification. (Yes, Even default calendar module can activate this)
 I wanted to make this universal.
- 
 How can I activate it with the H / W keys? 
 Only for test…@sean said in Start or not...?: You can activate with other module which can emit notification. (Yes, Even default calendar module can activate this) This function be done directly with “MMM-assistantmk2” or should I always install “MMM-Hotword”? 
- 
 @egnos function itself is included. But activating that function with hotword needs MMM-Hotword.
