Shelly EM goes Homematic - with original Firmware

SparkyMaster

By courtesy of 66er, i take over the text formatting with the technological routine. (Stefan, express thanks again at this point!))

Hello Homematic Friends,

to integrate the Shelly EM into Homematic, you do not need any third-party firmware, that you have to flash.

Below my solution with the original firmware:

techn. Requirements:

compatible with the Homematic systems CCU2, CCU3, Charly, as well as all offshoots like RaspberryMatic and piVCCU.
installed add-on CUxD in current version

(The knowledge about the handling CUxD, such as devices create, I assume at this point, otherwise "exploded" this guide Thank you for understanding.)

The advantages from my point of view:

all Shelly EM properties are preserved as I operate the actuators with the original manufacturer firmware
all future Shelly EM updates / updates will be usable
Full Shelly app usability in parallel with Homematic automation
Operation as local solution or via Shelly-Cloud, additionally Homematic

I implemented the following functions on the Homematic page:

ON OFF
Update of the current switching state in a freely adjustable interval, regardless of whether the operation is via Homematic or Shelly app or button
Optional monitoring of the online status (accessibility via WLAN)
Optional monitoring of currently power
Optional monitoring of currently voltage
Optional monitoring of currently reactive power
Optional monitoring of currently Total consumed Energy
Optional monitoring of currently Total returned Energy

A view to the connection:

Picture 1

I would like to recommend you to take a look at these threads before the implementation:

At the appropriate place in the manual, everyone has to decide for themselves which route the switching status monitor wants to use.

The implementation:

(On the description of the creation of the CUxD devices I give up at this point, of course there is the CUxD document!)

If not yet available, please create a device (28) System Exec! Above that the commands are issued. (No entries are made in CUxD-Exec!)

Creation of a CUxD (40) 16-channel universal control as a switch

CUxD (40) als Schalter.png

With each channel of the CUxD device, 1 Shelly EM can be mapped.

The settings of the channels:

The Shelly EM has two measuring channels to which two transducers can be connected.

Attention !: However, only one relay / switching output is integrated to control an external relay. When creating scenes or actions, the correct channel selection must be observed!

Einstellen der Kanäle.png

SWITCH|CMD_EXEC: Check mark!

Settings for SWITCH|CMD_SHORT:

Code

wget -q -O - 'http://192.168.178.33/relay/0?turn~3doff'

Settings for SWITCH|CMD_LONG:

Code

wget -q -O - 'http://192.168.178.33/relay/0?turn~3don'

Adapt the IP address of the Shelly EM in each case!

This makes the PlugEM ready for use and can be switched on and off.

Update the switch-state

The update is important, so that in Homematic the switching state is also correct, if e.g. via the Shelly app Pros and cons are described in # 1 linked thread.

For the autom. Updating the switching status we need 1 timer ...

CUxD Timer.png

Update every 60 seconds (time variable)

... that triggers the update program:

Programm Aktualisierung.png

Alternatively, in the IF, it is also possible to trigger on the "Timerevent" of the timer.

Missing only the script for the 1st THEN line:

According to the instructions in the script have to be adapted:

IP of the Shelly EM

CUxD Exec channel

CUxD channel of the Shelly EM

Now, the switching state of the Shelly EM is also updated in Homematic when switching via the app or Shelly scenes.

Optional ads:

1. currently power display:

evaluates the power of the Shelly EM channels, displays it in the CUxD device and of course the value can also be used in programs.

For this we need 2 system variable for the currently power value:

Systemvariable Leistung.png

The variables are assigned to the corresponding channel of the Shelly CUxD device. This makes it visible as shown in Figure 1 in # 1.

In the status updating program (see picture in # 2) we add a 2nd THEN line to update the power data.

Attention:

The names of the system variables must not contain any "spaces" !

In the set interval of the timer, the currently power is now updated.

2. Online Status:

As with all other couplings, the opt. display of the online status is also made using the system variable and CUxD ping device (28).

To display the online status, 1 system variable is required:

Systemvariable Onlinestatus.png

The variable is linked again to the corresponding channel of the CUxD device and thus displayed there.

The online status is monitored and controlled by a CUxD ping channel. That, with 1 CUxd Ping device (28) up to 16 Shelly EM can be monitored. Of course, a free channel of an existing CUxD ping can be used.

CUxD Ping.png

Adjust IP!

Settings for: SWITCH|CMD_EXEC_TRUE:

Code

extra/timer.tcl Onlinestatus_ShellyEM_Photovoltaik 1

Settings for SWITCH|CMD_EXEC_FALSE:

Code

extra/timer.tcl Onlinestatus_ShellyEM_Photovoltaik 0

Adapt the name of the system variable in each case! (here:Onlinestatus_ShellyEM_Photovoltaik)

In the set interval of the timer, the online status is now updated.

3. currently voltage display:

evaluates the voltage of the Shelly EM, displays it in the CUxD device and of course the value can also be used in programs.

For this we need 1 system variable for the currently voltage value:

Systemvariable Spannung.png

The variables are assigned to the corresponding channel of the Shelly CUxD device. This makes it visible as shown in Figure 1 in # 1.

In the status updating program (see picture in # 2) we add a 3rd THEN line to update the voltage data.

4. currently reactive power display:

evaluates the reactive power of the Shelly EM channels, displays it in the CUxD device and of course the value can also be used in programs.

For this we need 2 system variable for the currently reactive power value:

Systemvariable Blindleistung.png

The variables are assigned to the corresponding channel of the Shelly CUxD device. This makes it visible as shown in Figure 1 in # 1.

In the status updating program (see picture in # 2) we add a 4th THEN line to update the reactive power data.
