mqtt vs serial gateway on RPi

hasemar last edited by

Hi all, first post! I'm hoping this is the right category for this question. (There should really be a newbie question section!)

I currently am running a RPi 3 with Home Assistant (hass.io) installed. I used the image download for RPi3 on the website.

I also set up the MQTT broker via the hassio interface. I have successfully been able to control a few Sonoff Basic switches via MQTT commands.

I now want to integrate some sensors, I have a few Arduino Nano's and some nrf24l01+ radios that I want to use.

After reading through the MySensors getting started turtorials, I am still confused about the gateways.
How does it integrate with my controller? Should I use a MQTT gateway or a serial gateway?

I think the concept I am stuck on is the transfer of data from the radio to the RPi.

I'm sure this is a common question but after searching the forum, haven't found a post that really clarified it for me yet. Thanks in advance!

Ryan

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Thanks for the offer @TheoL ! I have moved on to a differenct project. Also, a lesson that I have learned many times, "If it works, don't fix it!" -OSD
No merge into master in the last 5 years, should we use development?

For me almost all I need is in Master. For some nice to haves I have some custom libraries, like a message and a presentation queue. The only wish I have is dual led support.

LiFePO4 batteries are a great choice because they have a long life cycle and are much safer than other lithium-based batteries. However, you need a solar charge controller that’s compatible with LiFePO4 to prevent overcharging and maintain efficiency. A good MPPT controller can significantly boost energy harvest from your panels. Also, ensure your solar panel output matches your power needs. If you're in solar ireland, you might find some local companies that offer tailored solutions for maximizing solar efficiency in lower light conditions.

@eiten Ran into the same error but of course the community is always at hand, ready to help! Great! I'm using MySensors 2.3.2 release version. Downgrading the ESP8266 board library to 2.7.4 as suggested by @OldSurferDude did the trick. I'm still clinging to MySensors. So simple and inexpensive to use! All sensors and other stuff connects over three MQTT GW in three locations back to my Home Assistant. PS: Get well soon! Regards, Gunnar

@Shirkit I agree. I have a lot of unifinished projects. Most of them still on breadboards. But as we will do a big reno on the house I need to finish them. Pretty sure I wouldn't be able to figure out how they worked if I store them in boxes during the reno. I have some light projects, A garden controller just an improved version of what was posted many years ago. And some more generic things that are probably not interesting to most people. And I also have a hub node the allows you to use cheap rf modules from AliExpress to control rooms very easy. I transformed a for channel remote module to a 15 button remote. Without this site I wouldn't be able to keep making MySensors stuff
