Piot project - Raspberry Pi

Perhaps you want to store data from your Annex projects or want to use MQTT without using a third party server. If you have a Raspberry Pi lying around any Pi will do even a simple Pi Zero W you can do all this on you home network.
I have put together a Rasp Pi image of EmonCMS and Node-Red that you can use on you Home Network for data storage and Visualisation, like OpenHab or Home Assistant but much simpler. You can use it to store data via HTTP, UDP, MQTT or even via serial directly from your ESP running Annex.
Here is a screen shot showing data from my home sensors and also some demo data via MQTT from a ESP8266 ( the power1 entry)
If you want to view sensor data/notifications that you can see when away from home the and don't want to use third party servers (been there , where do all those unwanted ads etc come from) just use an email account The Node Red can do all that for you, sending you alerts, data updates etc, also Node Red has nodes that can "read" an IMAP mail account so you could send commands/requests back to your home to request data , trigger event etc, securely without opening up your router.
If anyone is interested for more info or a copy of the image , just let me know and I will send you a link (its an image so its a big file)
