PiOT is the name I have given to a Raspberry Pi image I have made. Like many I imagine I have been experimenting with home data collection for several years, micromites, ESP8266 but more recently Raspberry Pi. I tried the RPI with mmbasic some time ago and that was successful but since I have spent a lot more time playing with Linux itself, that opens up a whole lot more possibilities. So to PiOT, silly name but i had to call it something! As the basis of the image is a PHP app called EmonCMS which is part of the Open Energy Project in the UK but it is a terrific application for logging data, it also has great facilities for Visualizations and Graphing. EmonCMS coupled with Node-Red , mmbasic and a Simple but Powerful CMS (Typesetter CMS 5.1) for a Web U/I. All this wrapped together as a "ready to go" RPI image , for me , makes the basis of a nice Home Automation System with fairly limitless functionality but could also easily be a quick way to a logger/controller for many other projects. The image is running Raspian Buster and is pre-configured as a headless system it has MMbasic installed which starts in a screen session on boot up so at the very least the img is an easy way to try Picromite. I will make the image available if any one want to try it anf will start some documentation on my website. Mike Here are a few screens from my working system.        Codenquilts |

Hi Mike, I have yet to make a start on remote monitor and automation. This looks like something I could try over xmas. Cheers Andrew |

Please do post the image. Does it have to be Buster? Would Buster lite suffice? On a pi-zw? How much of what your screen shots show is canned and what work is mmbasic doing? Nice job. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Hi Lizby, mmbasic plays no part in the Web interface. It is just one of the tools available in the "compilation" . In my case, for my current project for example , mmbasic performs some processing of my Grid electricity and roof PV supply data , it collects the data via UDP transmissions from the sensors, calculates then saves the results in a file. Node Red then reads the file and passes them on to the logger. Data from different sensors can be stitched together , logged , displayed etc by using the various applications as required. The image is based on Buster, I have not really tried a Zero , I think it would be asking too much . I will be posting the image tomorrow with some documentation. Codenquilts |

>I have not really tried a Zero , I think it would be asking too much . What about it is time consuming? I have a stretch lite pi-zw receiving udp messages and serving web pages now, with mmbasic doing some processing. Nothing to prevent my just flashing a new micro-SD, though. I assume your headless image would require editing of wpa_supplicant.conf on the PC before inserting into the pi? PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

>I have not really tried a Zero , I think it would be asking too much . For the Pi Zero, Single core and only 512 MB. Yes if you want to use WiFi you have to edit wpa_supplicant.conf , ssh file exists. Mike Codenquilts |

The Piot image is available you can download here , you will need a 32gb SD card and flash the card with Etcher. ssh should already be enabled but you will need to add wpa_suplicant.conf if you want to use wifi. user/passwords: Root is pi:emonpi2016 Emoncms piot:Happy@2019 TypesetterCMS admin:typepi2019 you should be able to access mmbasic by typing screen -r in a ssh terminal window.
