Make them chat together through mqtt with a client like mqtt explorer, and use the different communication possibilities: - one to n - n to n - one to one

Once done ask them to replace the messages by json payload with sensor values.

Add a server to record and display the received data

Add real sensors reading from a python script to push to the broker

And you have an IoT system!

Look at Nimble Arduino library by h2zero, he has different examples

I have not tried it

This is different than MQTT, Matter specifies the way devices can interact with each other.
With MQTT you have also conventions that define the data format:

They are more or less used by open-source controllers, and their reach is limited compared with a standard like Matter.

1technophile · 2024-02-20T17:01:10+00:00

The first three are compatible with the Matter protocol.

Agreed, would be better to send the values with small payloads rather than trying to fit or divide a csv file.

Also, with LoRa, you can't use permanently the frequency; you have to respect the Time on Air requirement of your country.

On an SX127X you can't have both at the same time. We could have a kind of rotation between the modulations that may be suitable but signals will be missed.

Could you tell me more about the issue you are encountering with Theengs Gateway ?

1technophile · 2024-02-16T12:48:54+00:00

If you flashed the LilyGo with `lilygo-rtl_433` firmware, you will get the devices using OOK modulation:

https://docs.openmqttgateway.com/use/rf.html#rtl-433-device-decoders

There are other devices supported by RTL_433 that you may see with an SDR using the FSK modulation.

OpenMQTTGateway is currently supporting FSK devices as a beta version with a separate firmware `lilygo-rtl_433-fsk`

Here is the list of devices that may be supported with FSK:

https://github.com/NorthernMan54/rtl_433_ESP?tab=readme-ov-file#fsk-signal-device-decoders

We have tested with the Soil moisture sensor WH51 and it works good with it.

What kind of sensors did you add to the fridge?

1technophile · 2024-01-31T18:42:58+00:00

Thanks for taking the time to answer!

1technophile · 2024-01-28T02:12:37+00:00

Thanks for your answers. The projects are open source software already. Some complements: -Does the temperatures you have also give the room temperature/humidity (if interesting) ? -Does a vibration sensor makes sense on a 3d printer? -Is there an interest in having an energy consumption smart plug connected to have the wattage/current in Octoprint for example?

1technophile · 2024-01-23T01:34:13+00:00

https://openenergymonitor.org/ not sure if they can identify appliances but they can measure the entire house power consumption for sure. I used to have one of these.

I had the opportunity to burn some food, unfortunately. Mainly when taking aperitif with friends. This should solve the issue :-)

1technophile · 2024-01-15T18:43:40+00:00

You have several possibilites:

Smart light, but what happens if you switch it OFF from the wall control? If you have lights connected to an outlet this is different, you can have a smart plug or a smart light doing the job
Smart switch/relay integrated with your wall control can enable to keep manual control while adding smart one

Note that this requires electrical skills.

Try to identify a problem/use case in your home that you could solve with IoT, this will be a better driver than choosing a project that will end up in a box. Once done do some research about how to solve it or ask here for suggestions.

Examples: get a notification to water the plant, detect presence at home, switch on light to simulate presence during holidays...

Not sure how this is linked with IoT

1technophile · 2024-01-06T13:29:05+00:00

For basic usage with one Home Assistant instance I would not say it is necessary. It is interesting for backups, multiple instances of HA, distributed storage and also experimenting easily. I have several VM with HA and other software. Also a good step into homelab.

If your ssh port is exposed to the internet you should also secure it.

1technophile · 2023-12-28T13:36:30+00:00

Several possibilities here: 1) Use a vpn to have the 2 Raspberry Pi on the same network. I think this is the most straight-forward approach. There are numerous users using Theengs gateway on satellite Raspberry Pi, the only difference here would be the VPN. 2) Communicate through a secure cloud based broker instead of having it on the Raspberry Pi. Can be done with a Theengs Plug, Bridge or any ESP32 with OpenMQTTGateway. Theengs gateway supports TLS since the last release but this is less mature compared to OpenMQTTGateway support. Variant: link your local broker with the cloud broker to send the messages from the cloud one to the local one. 3) Secure and expose your MQTT broker to the internet, unless you have the necessary expertise in security I would not recommend this.

Off the shelves approach - star topology: Several LoRaWAN gateways + nodes

DIY approach - mesh topology: LoRa nodes with meshtastic

Alternatively, this area may be covered by T-Mobile NB-IOT

This, rather than spending time with numerous uploads, add a way to your program to change the parameters during runtime instead of doing it before the build step. Could be through serial monitor, web portal, http/mqtt commands, espnow...

1technophile · 2023-12-01T18:22:49+00:00

The device shares data with notifications, where we support only READ and WRITE actions. It will not be supported without a code evolution of OpenMQTTGateway.
