why mysensors is based on nrf24?

[chbla]

Why based on nrf24? I came to the party late, but started with RFM69/433 - you are not bound to 2.4ghz in any way, it's just what people used to start with.

hi all friends . thank you for answer .
i mean about this , i think the combine mysensors network and domoticz controller is the best home automation . even better than fibaro , vera and etc...
In addition to the "cheap cost" reason , we are build every thing which we like. build sensors and devices that is not in brands for example my multi sensors. i can increase or decrease my multi sensor with every sensors in one node and one device.... for example i want have a gas and motion in one room and have gas and motion and temp/hum in other room...
these is excellent feature that there is not in home automation brands...

so i mean that is with this excellent features , with many trying from mysensors team(for design mysensors core) and members, why there is some weak in connection between !? i dont told nrf is bad ( i use this in my network several model but just a expensive model is work well for me and this is worthy for mysensors library :) other model work a few distance ) but with this excellent library and this excellent idea, nrf is not excellent choise .

why base of mysensors is not Mhz frequency (315 , 433) ? for report sensors or send command to relay and ack... are we need to Ghz frequency ?
i dont use RFM69 until now , but if RFM is better than nrf why mysensors is based on nrf? with RFM we are broader scope? with wall and more distance? RFM have repeater feature?and other feature?

[chbla]

It is not based, you can use a RFM69

[Reza]

we can build a network but this is not very easy and choose desired place for our nodes . or we must choose special place for better connection and signaling, or we must use repeater in special place ( perhaps there was not good place or wire power and etc... for repeater) also we must use a arduino and a radio for repeater just for weak in connection. so is this better that we have a connection with for example 20 meter in home with wall and if we want use more than 20 meter we must use repeater...?
now if i want have just 5 sensor in each corner in my home , for example i need 5 repeater or more :) :)
now domoticz have a excellent connection with each wifi device. for example milight and etc... so this is worthy that connection in mysensors network will be excellent even if cost will be more ( A little) :)

@chbla
do you use RFM69? this is work better than nrf? about distance and wall
RFM support repeater feature? and we can choose different channel ?

[chbla]

I'm using RFM69 yes, and it has no problems.
I don't need repeaters at the moment, as far as I know it's software based?

[Anticimex]

@chbla you are correct. The radio is fully supported and the repeater feature is a library feature, not a radio feature. It is a feature of the MySensors protocol.

[Reza]

thank you friends for answer.
about channel? MY_RF24_CHANNEL
can we use several channel with RFM ?
generally RFM work better than NRF ?

[Anticimex]

@Reza how about you read MyConfig.h?

[chbla]

@Reza it depends on the use case I think, peope are using both, both are working. NRF24 is easier to set up and seems to have more support. Just try it :)

[Reza]

for help to my friends that use NRF. i test several model. but most are not really range.this model was best of NRF. with this model i have connect with 60cm wall and 10meter distance.
if you want have a good connection, so use this model:

but i think NRF is not worthy mysensors and efforts of mysensors team :pray:

[Reza]

@Anticimex said in why mysensors is based on nrf24?:

@Reza how about you read MyConfig.h?

i am weak in english sorry i know repeater feature is in mysensors library, but i think about channel i think this is just for nrf. is that right ?

@chbla i am very happy with mysensors. i have very sensors and relay and every day i am try to build a new sensor and a new devices :) if there was a stronge and good and easy connection so this was very more intresting

[tbowmo]

I think you have missed a couple of details @Reza

When mysensors started out, the cheapest / best approach was to use the nRF24L01, rfm69hw was not available. So the project evolved around this radio. The RFM69 came in at a later time.

Unfortunately a lot of Chinese saw easy money, with counterfeit chips, and started to create less than optimal fake versions. That will probably also happen to rfm69hw (and are probably already there).

So we keep nrf, as it is there in the core.. It's up to you and other hackers, to decide what you want to use

hey dear friend,

be like water ;)

[Anticimex]

@Reza If you read MySensors.h you will find what configuration possibilities the various radios have. Try looking for information instead of just begging for it all the time.

[Reza]

@tbowmo
oh thank you for explain :pray: and thank you all mysensors team. really thank you. mysensors is intresting really. i try to found best and easy and without any trouble of solution for connection . we are easy to build all sensors and relay(with mysensors library) so this is intresting more to easy , very easy connection between rooms... :)
again thank you all mysensors team and hero members :pray:

@Reza so, topic closed?

@Anticimex dear friend , i am trying for learn and work well with mysensors library , arduino and radios...
believe me i trying every days. now for 1.5 years. i am trying every days. but some time i dont know where found my problem and my question. i start learn arduino with mysensors library. because i am Interested very very. now i can write each sketch for sensors and relay. this is for your help .thank you

[Anticimex]

@Reza have a look in the file. It's designed to offer clear understanding of the various configuration options. And gives you a good overview of what settings you can place in your sketch to configure the library to your needs (what radio to use, what channel, transmit/receive power, pin assignments, etc.)

hi. yes thank you. i see forum and site every days and read new topics and Newest Articles and Recently Updated :)
i hope mysensors development every days in all of world , and the team be healthy always.
thank you
