Can’t figure out what’s wrong with this, the state value shows values > 0 however the displayed icon is permenantly showing the “wifi-strength-alert-outline” icon.
What am I doing wrong ?
sensor:
- platform: wifi_signal
id: wifi_sig
name: Signal
- platform: template
name: "Signal"
id: wifi_bars
entity_category: diagnostic
on_raw_value:
then:
- lambda: |-
if(x==4.0) id(wifi_bars).set_icon("mdi:wifi-strength-4");
else if(x==3.0) id(wifi_bars).set_icon("mdi:wifi-strength-3");
else if(x==2.0) id(wifi_bars).set_icon("mdi:wifi-strength-2");
else if(x==1.0) id(wifi_bars).set_icon("mdi:wifi-strength-1");
else id(wifi_bars).set_icon("mdi:wifi-strength-alert-outline");

Im not sure exactly what value X is at the time your lambda test happens but based on your structure you’re falling into the else clause because nothing matched.
Is the data type on X a number or a string value?
Thanks, I have re-written this to use a string value, the template set’s it’s state value based on the signal strength from wifi_sig.
sensor:
- platform: wifi_signal
id: wifi_sig
name: Signal
update_interval: $refresh
text_sensor:
- platform: template
name: "X Signal"
id: wifi_bars
entity_category: diagnostic
update_interval: $refresh
on_raw_value:
then:
- lambda: |-
ESP_LOGI("main", "Value of my sensor: %s", x);
ESP_LOGI("main", "State: %s", id(wifi_bars).state);
if(x=="4") id(wifi_bars).set_icon("mdi:wifi-strength-4");
else if(x=="3") id(wifi_bars).set_icon("mdi:wifi-strength-3");
else if(x=="2") id(wifi_bars).set_icon("mdi:wifi-strength-2");
else if(x=="1") id(wifi_bars).set_icon("mdi:wifi-strength-1");
else id(wifi_bars).set_icon("mdi:wifi-strength-alert-outline");
lambda: |-
if (id(wifi_sig).state >= -30) return (std::string) "4";
else if (id(wifi_sig).state < -30 && id(wifi_sig).state >= -67) return (std::string) "3";
else if (id(wifi_sig).state < -67 && id(wifi_sig).state >= -70) return (std::string) "2";
else if (id(wifi_sig).state < -70 && id(wifi_sig).state >= -80) return (std::string) "1";
else return (std::string) "0";
Strange thing is although the state of the sensor reflects the correct state of “0” to “4”, when I log the variable x or if I get the sensor state instead, it is not the state value:
[14:31:50][D][sensor:127]: 'Signal': Sending state -62.00000 dBm with 0 decimals of accuracy
[14:31:54][D][text_sensor:067]: 'X Signal': Sending state '3'
[14:31:54][I][main:046]: Value of my sensor: 0\xca?
[14:31:54][I][main:047]: State: 0\xca?
I think that value is hex and is the actually signal strength in dB (assuming a signed int): -54. That’s why it executes the if that gives 3.
Even this does not set the icon, yet the number of bars values (“0” > “4”) are set correctly !
- platform: template
name: Wifi Signal"
id: wifi_bars
icon: "mdi:wifi-strength-alert-outline"
entity_category: diagnostic
update_interval: $refresh
lambda: |-
if (id(wifi_sig).state >= -30) {
id(wifi_bars).set_icon("mdi:wifi-strength-4");
return {"4"};
} else if (id(wifi_sig).state < -30 && id(wifi_sig).state >= -67) {
id(wifi_bars).set_icon("mdi:wifi-strength-3");
return {"3"};
} else if (id(wifi_sig).state < -67 && id(wifi_sig).state >= -70) {
id(wifi_bars).set_icon("mdi:wifi-strength-2");
return {"2"};
} else if (id(wifi_sig).state < -70 && id(wifi_sig).state >= -80) {
id(wifi_bars).set_icon("mdi:wifi-strength-1");
return {"1"};
} else {
// id(wifi_bars).set_icon("mdi:wifi-strength-alert-outline");
return {"0"};
}
Are you certain you can change the icon at “runtime”? Does HA even support that?
You might be onto something, so I Googled: Icon template with ESPHome cover .

Well I’ve always assumed that this whatever state / attributes changed would be reflected in the UI ?!

Hi,
I have added following to the yaml file
- platform: wifi_signal
name: "Wifi_signal_db"
id: wifi_signal_db
update_interval: 5s
entity_category: "diagnostic"
- platform: copy
source_id: wifi_signal_db
id: room1_db
name: "Wifi Signal %"
filters:
- lambda: return min(max(2 * (x + 100.0), 0.0), 100.0);
icon: >-
{% if sensor.room1_wifi_signal >= '52' %} mdi:wifi-strength-4
{% elif sensor.room1_wifi_signal < '52' %} mdi:wifi-strength-3
{% endif %}
unit_of_measurement: "%"
entity_category: "diagnostic"
I am gettting following errors
Icons must match the format "[icon pack]:[icon]", e.g. "mdi:home-assistant".
As adanced users here can see, I am new to home assistant, can somebody guide me in solvoing the problem ?
Thanks and Regards

Once , I upload the file to ESP after validation , I am able to see the icon change, but it happens only once.i.e
Thanks and Regards
