Hi Sara,
I have looked at this project and I am still not convinced that this is the right project for me.
I follow the ESP32 Web server e-book and use Item 2.2 which has 4 on/off buttons which control 4 outputs on my ESP32 via Computer IP address or on my Mobile Phone which works fine indoors. What do I need to do to control the same but anywhere outside of my own WiFi.
Many thanks

Hi.
Check the variable type and if it is not introducing any non-visible characters like /n , or ”
You may need to convert to char or string.
Regards,
Sara

Hi Sara santos
It would be really helpful if u can reply to this query, I have tried many times it’s not working.
If we hardcode the esp32 with telegram bot id it works, but if we hardcode that using wifi manager it’s not working, can u please help.

Hi Sara,
here I am … again !
I made a gruop of 10 sensors, light controller, yard controller and so….
All run perfectly (thank U so much)
Now, I wanna ask U: it’s possible get a multiple command to the members of the group?
For example can I ask the temperature ( /temp ) and I’d like all the members get an answear.
Is it possible, cause i did some tests …. for nothing.
Thanks a lot Renzo from Italy

Hello there,
I programmed the WeMos d1 mini as shown and it works ok when I enter the commands in the telegram app both on my iphone and Android tablet.
My 3d option is to use VBA Excel to send a message to the telegram bot. When I do this I see the instructions appear in telegram, but the led will not switch on or off on the WeMos d1. Also I don’t see anything in the serial monitor when I use the excel macros.
Anyone any idea how to solve this?

Recreated this project with ESP8285 and 6 LEDs – worked like a charm. Thinking about creating an RC car for my group just for fun

hey,

Does someone know if i can get the name of my bot with a command? For example bot.messages[i].from_name gives me the name of the user who send a message but i want to get the name of the bot (for example @my_bot).

kind regards
