Additional values on main menu site

[Toto1308]

Hi all,

I tried a lot of things now, but I do not get it right. Hopefully you can assist me and give a hint.

My settings:

• Tasmota 14.6.0.2
• INA219 as sensor
• use_script enabled
• use_rules disabled

Problem:
I like to use the voltage of the INA219 sensor and do a multiplication and division to get a different value. That value is e.g. a hight. Now I want to show this value directly on the main page of the tasmota page below of the three INA219 values. How can this be done only with the edit script page on the tasmota device?

Please find attached a screenshot of the mainpage.

Actually I use the following script:

`>D
=>volt [INA219#Voltage]
=>hoehe [volt] * 138 / 3.3
=>liter [hoehe] * 5600 / 138
=>prozent [liter] * 100 / 5600

Var1 Höhe=[#hoehe#] cm
Var2 Inhalt=[#liter#] L
Var3 Füllstand=[#prozent#] %`

Many thanks for your help in advance.

Regards
Thorsten

Not using the scripter, but AFAIK, you can use the >WS section to have sensor-like values on the front page, like:

>WS
Temp In{m} %1tempin% °C

The number before the variable name is decimals.

Thanks for the hint. I have tried now the following script, with no change on the main page... Any further suggestions?

>D
hoehe=(%VOLTAGE%*138)/3.3
liter=(3.1416*(230/2)^2*hoehe)/1000
prozent=(hoehe/138)*100

>WS
Zisterne Höhe %hoehe% cm
Zisterne Volumen %liter% L
Zisterne Füllung %prozent% %

I have the script editor active - so do you mean something else?

[sfromis]

No, I did not mean "something else". Of course, you should save the script before it becomes active, but I suppose that you did that already....

The binary I used was not one I compiled myself, but the "unofficial" tasmota-scripting development build, but that should just be normal for having a build including that feature.

BTW, as the docs mention:

Requires compiling with #define USE_SCRIPT_WEB_DISPLAY.

Thx - I now can see the three lines. I build my version again.

Now I still struggle with the calculation. This seems not to work.

Now I get my calculations done with the following script:

>D
hoehe=0
liter=0
prozent=0
spannung=0

>S
spannung=spannung+1
hoehe=((spannung*138)/5)
liter=3.1416*115*115*hoehe/1000
prozent=hoehe/138*100

>WS
Wasserhöhe{m} %hoehe% cm
Volumen{m} %liter% L
Füllung{m} %prozent% %%

How should the line spannung=spannung+1 look like if I want to use the INA219 Voltage. How can I find out the right variable name?
