there is a Linux version that works great. that way you can alsorunn mqtt server on the same raspberry pi. I am using a 3B for this install
We have a community radio station here on Hatteras Island, NC. Its primary purpose is to provide emergency services to keep both locals and visitors informed on various emergency situations. When the internet and other comms are down, the FM radio station is one way to keep people up to date. It is an all volunteer station. I am one of the engineers keeping the station running. When we are not in "emergency mode" (which is most of the time), we broadcast rock and roll music (primarily from the 60's, 70's, and 80's). Here is a brief view of the transmitter room. You can get more info about our radio station here (we also have a live streaming feed if you are not in the area) https://www.radiohatteras.org/

This is one of my gardens that is a hybrid wicking bed. I use cloth grow bags with soil that allows the roots to air prune. I also have a floater valve that connects to the hose to auto fill with water when needed, allowing for wicking into the grow bags. I also use tiny stones to cover the water line to keep the mosquitoes for using this as their nursery for little baby blood suckers. The video has sound that has some explanation.

I am experimenting a bit with Lora and Meshtastic mesh networking. I wanted to see how it could track me as I did a prone paddle out in the sound. Since I am only a few inches from the water, and the node I was carrying didn't have its antenna vertical, transmitting probably wasn't ideal. But at only 60mW, this aint bad. Looking at the first pic, the red dots with the diamond in them are the beacons. The cluster is home base. The one the furthest north is about a mile from home base. I did paddle well around Brooks Point this morning, so I wasn't getting received all the way home. I just need to find a friend in Brigands Bay who would be willing to put a node out on their deck to add to the mesh 😉
I used a T-Beam lora transceiver on my paddleboard (with the factory crappy antenna). At home base, I have a similar device with a high gain antenna outside. I then have a Raspberry Pi with a Lora tranceiver on it in the house that is part of the mesh. It takes data and then pushes it to an MQTT server that is on the same Raspberry Pi. I have another pi running node-red that listens to the MQTT server and bridges the data over to my ThingsBoard server that has a Postgres database. I queried the DB for the specific node and mapped on Google Maps. Lots of steps, but something easily automated with a little code.

What do you do when there is an onshore wind from the East or the SE? Go paddling on the sound. Super glassy. Water super warm. Awesome workout! Wind almost non-existent. Air and water temp in the mid 60s.

Wind was pretty strong with some gusts almost 20mph out of the west to WSW. I made a mistake to ruck in sheltered areas. Of course the mosquitoes had the same idea.

Geeze. My keyboard went crazy on that comment.
We live onian island total commsoutagess (landline, cell, internet,and 911 service). Plus we are in a hurricane prone area. Plus it isfunn to play with.
Beautiful morning. Soon the sunrise will be early enough to go surfing before work. Temperature is perfect. Light offshore wind. The higher tide keeping the surf from getting to drained out on the sandbars

Just started looking at Garnet. Do you have use cases for this? I can see high speed IoT or blockchain. Just trying to find out what use this would be over "normal" databases.
Some have asked what I have been using for my Meshtastic setup. I have a few things that I am using:
LILYGO LORA32 T-Beam: I am using this for my mobile use since it has an 18650 battery holder. I connect to this either from my laptop or my phone via bluetooth
Heltec V3 (wifi and LoRa): I got a two pack of these form Amazon. I am using 2 of them for different things
- One I am using to connect to a high gain antenna on my roof. This allows me to connect to other devices in my area.
- The other, I have setup for WiFi instead of bluetooth. I am using this to bridge traffic over MQTT. This allows me to have others who arent in my area also subscribe to the same channels and have MQTT send messages from my Meshtastic mesh network to theirs in another part of the world by using the internet as a bridge. (NOTE: the device I am using for this is connected to a Starlink router so normal terrestrial outages of internet wont affect it like cable cuts, etc) -- Another NOTE: I am waiting for a Raspberry Pi LoRaWAN hat to come in. I will be replacing this device with a Raspberry pi to get more capability.
Here is some of the equipment I am using for the antenna for the device that I have up on the roof:
Rokland 915 MHz Antenna
Depending on what type of connector is on your device, you may need to get a pigtail to fit the antenna connector. This is what I got:

what problem are you having? I have one meshtastic device attached to a high gain antenna on the top of my house. with another one that I use with my phone. I have also put one that is using wifi instead of bluetooth so that I can bridge MQTT. I dont have any problems. but I only connect my phone to one of the mehtastic devices. the others are for bridging or the one with high gain antenna is for getting distance to a buddy of mine who has a device about 4 miles away.
wow, 10,000 mAh battery. Most of these things just have made up numbers and arent what they say they are. But, for the price, I had to give it a try. I want to see how long it will keep an ESP32 device running without any solar backup. Especially if the ESP device sleeps most of the time and wakes up every 15 minutes to take a sensor reading, send the data via WiFi, and then go back to sleep. This battery is a hoss though. Almost the size and weight of a cell phone.

We had a decent rain yesterday. Our NWS weather gauge reads 0.285", but I can only report to two significant digits, so I am going to put it at 0.29". Our digital weather station says that the event was .24". So, relatively close. The NWS weather gauge, while analog, has a larger catch funnel and is more out in the open. It is a nice cool morning in the upper 50's. The wind has died down considerably. But, we had some heaving gusts last night around 1am.

I have had with my high gain antenna at my house and a smaller mobile unit in my jeep get about 5km. I have heard up to 10. but, I havent seen it. I am working with another guy here on Hatteras Island and we are looking to get as near to 100% coverage with 20 Lora radios
I am going to get a parts list together on what I have done and post it in the next week.

Resurrecting my mesh network networking project using #meshtastic. got my outdoor unit setup with a high gain antenna and solar charging. Will then be able to send telemetry and messages across the network without the need for the internet. Will also bridge to the internet using MQTT
Calm before the storm. You can really notice the petroleum smell in Buxton. Smells like El Portal in southern California. And Porto was right next to a Chevron plant. I hope they figure something out.

What a difference a day makes. Wind died down. Still in the 40s this morning, but very nice on the south facing beaches. Surf, still a bit sloppy, but cleaning up. Lots of moisture in the air making it a bit foggy.
