Description:

My Wanhao Duplicator i3 printer was still running on its initial firmware. This firmware lacks thermal runaway protection which is an important feature which can prevent fire. Thermal runaway protection stops heating the extruder when there is no temperature increase for a set period. This can happen when your thermistor is disconnected for example. I [ ] I ve created an S0 Counter to measure (Solar) energy using an external kWh Pulse meter. This time using an Arduino Yun which can upload the data to PVOutput.org and provide the data via MQTT.Read the article I ve created a mount for the Sensus 620 watermeter to mount a  LJ18A3-8-Z/BX-5V proximity sensor on top of it. The sensor is connected using the schematic which can be found here. Instead of using a Raspberry Pi, I use a Wemos D1 with Tasmota firmware. The 3D print design can be found on Thingiverse. I am using Docker containers on my Synology NAS to run all kind of different servers like Domoticz, Node-Red, Unifi, Nginx, Mosquitto and so on. Although this is working quite well most of the time, the Docker GUI in Synology is not always the best interface. One of my colleagues pointed out he uses Portainer [ ] Today I found a new app for the Apple watch which allows you to send information to the watch face or complication as Apple calls it. The app can be downloaded from the app store and is named Complicated . The site of creator can be found here: https://mikelyons.org/complicated/ You can use IFTTT, Zapier or other [ ] Over the past years I ve used several brands of WiFi accesspoints. Way back I started with one of the first Cisco 802.11b accesspoints with only 11mbit. Meanwhile accesspoints of Linksys, Dlink and more recently the Apple Airport Express accesspoints have been used. Actually they all offered wifi and at the time of use an appropriate [ ] This post was still in my drafts for maybe 2 years now. Not sure if it is complete, but it did remind me of the nice tool SmokePing . I m using Open Monitoring Distribution as a decentmonitoring setup on my local and some customer networks. It isn t a 5 minute setup though and sometime you just [ ] I finally found some time again to build some LoraWAN Arduino toys for TheThingsNetwork. Basically it s just a temperature sensor measuring outdoor water temperature and sending it once in a couple of hours via TTN to my Node-Red install. I ve used the RN2483 library from JP Meijers which works great. I use an Arduino Pro [ ] An updated version of Open Monitoring Distribution (OMD) is available at the Bananian site here. They ve build it for the ARMv7 (BananaPi, Raspberry Pi 2 3, OrangePi). I ve written a complete install manual for version 1.00 which should work for version 1.30 too. Just make sure you use Raspbian Jessie. The related Check_mk_agent files can [ ]
