Mine arrived today. Holey shit that app is bad.
I cant even get my Shelly EM to connect to a local wifi network.
I connected to the EM’s local network.
Under user settings in the app I filled in the batch wifi update settings (2.4GHz network SSID and PWD) and selected both power meters that appear. Hit update but nothing appears in my DHCP server.
EDIT: I deleted the app and just used the web settings.
EDIT 2: Also if anyone is looking for an RSSI sensor, this works:
- platform: rest
name: Shelly EM Wifi
resource: http://10.1.1.24/status ### Edit to use the IP of your Shelly EM
username: !secret shelly_usr ### Only required if you have set a password
password: !secret shelly_pwd ### " " " "
authentication: basic ### " " " "
value_template: '{{ value_json.wifi_sta.rssi }}'
scan_interval: 180 ### Feel free to make faster, 30 or 60 sec would be fine
unit_of_measurement: dB
Edit 3:
Another trap for players, who the flock uses Watt-minutes? Ugh. Fix:
- platform: mqtt
name: "Tariff 31 Energy"
state_topic: "shellies/shellyem-B9E940/emeter/0/energy"
value_template: "{{ value|float / 60000 }}" # Fix for Watt-minutes
qos: 1
unit_of_measurement: "kWh"
icon: mdi:chart-bar
- platform: mqtt
name: "Tariff 41 Energy"
state_topic: "shellies/shellyem-B9E940/emeter/1/energy"
value_template: "{{ value|float / 60000 }}" # Fix for Watt-minutes
qos: 1
unit_of_measurement: "kWh"
icon: mdi:chart-bar
EDIT 4:
But ignore those sensors because they wont work with the Utility meter if you want a daily energy used sensor (they reset to 0 if no power is used for a minute). You need to use a rest sensor to interrogate the yearly totals like this:
- platform: rest
name: Tariff 31 Total Energy
resource: http://10.1.1.24/status
username: !secret shelly_usr
password: !secret shelly_pwd
authentication: basic
value_template: '{{ value_json.emeters.0.total | float /1000 }}'
scan_interval: 300 # no point updating faster than this. The Shelly only updates this every 5 minutes
unit_of_measurement: kWh
- platform: rest
name: Tariff 41 Total Energy
resource: http://10.1.1.24/status
username: !secret shelly_usr
password: !secret shelly_pwd
authentication: basic
value_template: '{{ value_json.emeters.1.total | float /1000 }}'
scan_interval: 300
unit_of_measurement: kWh
Used in the Utility meter:
utility_meter:
daily_light_and_power:
source: sensor.tariff_31_total_energy
cycle: daily
tariffs:
- peak
daily_heating:
source: sensor.tariff_41_total_energy
cycle: daily
tariffs:
- offpeak
You can omit the tariff configuration. I only needed it as you cant use the reset service without them and testing required a bit of resetting.
All of this shenanigans could have been avoided if Shelly provided a daily energy used total. Like every other freaking smart power meter on the market.
