I have one scooter, using arduino and rf 433 receiver, I remotely started it with a 433mhz control. When it is 10 meters away, only behind a wall, it does not pull and the engine does not work. There are many products, so I am confused, which product would you recommend to buy?
NRF24L01, nRF24L01+ PA 2.4,
Cc1101, Hc-12 which one should I choose?
I want to start it from home and let the engine warm up until I get to the scooter, it's only 10m away from the balcony but a wall cuts the signal, it's not open space
ESP32 @ 200 meters.
A strange member of the forum chose to make fun and be offensive instead of helping, and I complained to the management as a result, those comments were deleted by the management, that's why the comment numbers look like this.
Returning to our topic, esp32 does not work for me, I want to work on Rf 433, not wifi.
Hello turqut74
for a long time I have been following the topic with the use of this type of wireless module and the associated software functions.
For wireless projects I recommend the use of the HC12 module.
What are the advantages:
- no external functions from a library are needed.
- the development of a communication protocol is in your hands
- the necessary development steps can be programmed and tested without using the wireless module
- the radio module can be easily configured for the project requirements
- both transmitter and receiver are contained in one radio module.

Have a nice day and enjoy coding in C++.
You said in post #1 this does not work at 10m. ESPNOW can give you 200m. But if you want to pursue 433... okay... I can not.
[late edit]
This is from a ESPNOW web site. I read it as "not WiFi":
Espressif, the makers of the ESP8266 and ESP32, have developed a protocol that allows all these devices to create a private, wireless network using the 2.5GHz transceivers. This is a separate network from the WiFi network and can only be used by ESP-type microcontrollers.
I bought the model with NRF24L01 + PA + LNA SMA Antenna
The scooter stays within 4 meters of the area indicated by the arrow.
Scooter with a trunk????
maybe it is lost in translation, but that key fob is for a CAR with a trunk open feature... so how does that work for a scooter??!
Yes, for the car, but I use it on the scooter, the seat was opened manually with the key and I did it automatically, the trunk button opens the seat, I used the remote start and other keys as the engine electrical lock.
ah... starts making sense why to what to keep using the 433MHz receiver!
you probably need so kind of antenna setup if you want it penerating walls. Found this discussion on the forum which I found insightful

hope that helps....
