This is is a short demonstration of a co-simulation between Siemens PLCSIM Advanced and C#.
The goal is simple : have the ability to conditionally change inputs.
We’ll do a proof of concept with a small exemple for a safety relay monitored by a feedback.
The goal of the project is the integration of a Saunier Duval boiler with a Domoticz home automation system.
It’s possible to update a RFLink gateway from your Pi running Raspbian and Domoticz.
Before :
After :
Install Avrdude :
|
1 |
pi@pi:~ $ sudo apt-get install avrdude |

Monitoring my Raspberry Pi network behind NAT is easy using OpenVPN and Zabbix agent/server.
In a few cases, I need to monitor hosts without any possibilities to install OpenVPN and Zabbix agent on it (switchs, routers, wemos, arduinos…).
Continue reading Monitor a host from a Zabbix Agent (ping / ICMP)
Once the server is ready, we can start to configure our agents.
Install the zabbix-agent :
|
1 |
sudo apt-get install zabbix-agent |
Edit the configuration file :
|
1 |
sudo vi /etc/zabbix/zabbix_agentd.conf |

Initial steps :
– OpenVPN server
– OpenVPN client
– Rsync server
Then we are ready for this step !
Create folders for our daily backups for “bart” :
|
1 |
sudo mkdir -p /var/backups/raspberry/bart/daily/{1..7} |
Continue reading Raspberry pi backup using Rsync server and OpenVPN
Create/edit the Rsync server configuration file :
|
1 |
sudo vi /etc/rsyncd.conf |
Here is my configuration file:
|
1 2 3 4 5 6 7 8 9 10 |
uid = nobody gid = nogroup max connections = 50 socket options = SO_KEEPALIVE address = 10.8.0.1 [raspberry] path = /var/backups/raspberry/ comment = Rpis backups read only = no |
RFLink is a great, flexible and opensource RF gateway for 433Mhz devices. I use it with Domoticz. Every few months, a 
new firmware is released and they add a lot of new devices. This post describe how to update an RFLink gateway in a Linux environment.
