Hi guys,
I´ve just purchased the Shelly 3EM device and connected it to the Home Assistant.
The entity itself is working properly and fine, but I have few problems:
As I am measuring 3 phases and I need to calculate all 3 phases together, I created a helper (sum of devices) - which calculates all 3 phases as a sum AND a template like this:
template:
- sensor:
- name: "Kotel"
unique_id: kotel_energy_total
state: >-
{{
[ states('sensor.shelly_celkova_spotreba'),
] | map('float') | sum
}}
availability: >-
{{
[ states('sensor.shelly_celkova_spotreba'),
] | map('is_number') | min
}}
unit_of_measurement: kWh
device_class: energy
state_class: total_increasing
The problem is, that when I add the entity (the helper), it shows me correct data.
Total measurement for all 3 phases together.
For example now I have 134,33 kWh.
When I look at the energy dashboard, there is a different number.
At the same time as above, it shows 130,99 kWh.
And - I selected the fixed price - 2,43 CZK / 1 kWh.
And the energy panel shows me 111,68 CZK.
This of course is not 2,43 * 130,99.
It should show 318,3057 CZK.
I have waited till the second day that maybe the prices will be fixed by itself, but no success.
Can anyone guide me, what could be the problem?
