WiFi signal strength and ON/OFF icon

[tomik671108]

Hi.
Would it be possible to add the value of the thermostat's WiFi signal strength to the upper left corner?
My entity:

` sensor:
- name: "heater_WiFi_B_gabinet"
icon: mdi:wifi
unit_of_measurement: dB
device_class: signal_strength
state_topic: 'BHT_B_gabinet/rssi'

`The second request is to separate the NO/OFF thermostat power switch icon as a separate entity ?. The current version doesn't work for me.
My entity:

switch: - name: "heater_OnOff_B_gabinet" icon: mdi:power state_topic: 'BHT_B_gabinet/1/get' command_topic: 'BHT_B_gabinet/1/set' <<: &buttons payload_on: '1' payload_off: '0' availability: - topic: BHT_B_gabinet/connected

Thank you for your great work.
