First off, here is the latest State of IO post from Todd:
Here are the stats for the past week:
* 30.21 million inserts of logged data in the last 7 days * 10,086 users * 7,766 online feeds (21,498 feeds total) * ~50 inserts per second via MQTT * ~5 inserts per second via REST API
After some load testing, it seems that our current server configuration is able to handle more traffic. Our current theory is that the inserts per second aren’t rising evenly with the increased online feed count because users are using IO for real-time interaction, and not data logging. Inserts per second only seem to rise with heavy and persistent data logging projects.
We have been testing the new Feather LoRa Radios with IO, and they seem to be a fantastic pair. We were able to send messages to IO through a LoRa gateway from 1.27 miles away in the rolling hills of central Maryland using a small wire antenna.
Pretty impressive for not having line of sight to the gateway!
In case you missed it last week, another amazing Adafruit Feather product that we just released is the Relay FeatherWing. As you can see from the Relay FeatherWing guide, it is super easy to control higher powered devices with the Relay FeatherWing and Adafruit IO.
A Feather board without ambition is a Feather board without FeatherWings! This is the Latching Mini Relay FeatherWing. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board.
The are two ‘flavors’ of these FeatherWings, this is the Latching relay. This one requires two pins, a SET and UNSET and instead of keeping the SET pin high, you only have to pulse each pin high for 10ms to latch the relay open or closed. You need two pins but save power. Note, if power is lost, the relay will stay in the last setting.
The other type of relay FeatherWing is the simple Non-Latching relay, it requires only a single signal pin.
Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the internet. There are certainly a lot of great services out there for datalogging, or communicating with your microcontroller over the web, but these services are either too complicated to get started, or they aren’t particularly fun to use. So, we decided to experiment with our own system, and that is how Adafruit IO got started.
We also have a blog/changelog specifically for Adafruit IO to keep you updated with the latest changes.
To make it easy for people to get started using Arduino or ESP8266 we have starter packs with just about everything you may want to connect to the internet, with known-working WiFi modules!
