Would possibly also work to use a RestFul command but that will end up as an service that you then need to handle:
Thanks for this post! It really helped a lot!
Thanks to everyone else who contributed as well.
I can now control a shelly device that is NOT on the same network as the Home Assitant instance, and receive status updates from the shelly.
Great use cases are:
- Garages or gates that are out of range (Though some internet connections is still required.)
- Garages or gates you have permission to access, where there is internet but no Home Assistant. (Offices, family member homes)
- Basic Monitoring of remote properties
NB: Always beware of the security risks of putting access control onto a cloud system. If you don’t understand them, don’t do it.

Can anyone give me some help?
I’m trying to get the voltage from a Plus Uni
rest:
- resource: https://shelly-77-eu.shelly.cloud/device/status
method: POST
payload: 'auth_key=123456789abcdefg&id=AAAAAAAAAAA'
headers:
User-Agent: Home Assistant
Content-Type: application/x-www-form-urlencoded
scan_interval: 5
sensor:
- name: "Caddy Battery (Cloud API) - Voltage"
value_template: '{{ value_json.data.device_status.voltmeter.100.voltage }}'
device_class: voltage
unit_of_measurement: 'V'
Im sure my value_template is wrong
With recent HA updates this is broken now… not sure how to resolve.
Logger: homeassistant.helpers.template
Source: helpers/template.py:2652
First occurred: 09:41:21 (21 occurrences)
Last logged: 09:51:21
Template variable error: dict object has no element 0 when rendering '{{ value_json.data.device_status.ext_temperature[0].tC }}'
I used to be able to get reading with this, but it is not working anymore…
- platform: rest
name: "Solar Battery"
device_class: voltage
unique_id: solar_battery_id
resource: "https://shelly-31-eu.shelly.cloud/device/status?id=12345678&auth_key=12345678"
method: POST
value_template: "{{ value_json.data.device_status.adcs[0].voltage }}"
unit_of_measurement: "V"
actualy it works, but it is not updating.
Temperature is not working…
{{ value_json.data.device_status.ext_temperature[0].tC }}
Looks like shelly output is different now… Voltage works now, i found that shelly cloud server changed, now updated yaml. Temperature is still not working.

Is there a solution to this?
Interestingly, the switch (relays) works, but the temperature (ext_temperature) does not.
Template variable error: dict object has no element 0 when rendering ‘{{ value_json.data.device_status.ext_temperature[0].tC | round(1) }}’
You probably need to make it ["0"]
Hi,
I tried all the suggestions what you’ve all posted here, but nothing works.
I have a Shelly Plus Uni and want to see the Voltage in HASS.
Here is the code:
sensor:
- platform: rest
name: "Trabant Garage Batterie"
device_class: Battery
unique_id: trabant_garage_batterie
resource: 'https://shelly-118-eu.shelly.cloud/device/status?id=123456&auth_key=ABCDEFG'
method: POST
value_template: '{{ value_json.data.device_status.adcs[0].voltage }}'
unit_of_measurement: 'V'
When I add the complete ressource string to the address bar in the browser I see the data, this is working.
In HASS I get this:
I would be glad if someone can help me to solve this.
Many thanks in advance 
Has no one an answer how to solve this?
It still will not work and I don’t understand why.
Is there anything further to do in HASS to activate REST or something?
Did you try what I posted just above your comment?
Yes, but still not working.
I tried all solutions in this article before I raised my comment.
Do you have any other idea?
I have this in my configuration.yaml
- platform: rest
name: front_water_tank_rest2
unit_of_measurement: "v"
resource: https://shelly-76-eu.shelly.cloud/device/status
method: POST
payload: auth_key=insert your key&id=insert your id
scan_interval: 30
headers:
User-Agent: Home Assistant
Content-Type: application/x-www-form-urlencoded
value_template: "{{ value_json.data.device_status.adcs[0].voltage | default('N/A') }}"
This creates a sensor called sensor.front_water_tank_rest2 and returns the voltage. I have cloud enabled on the device.
