I have a few Raspi's runing.
I have had issues once that domoticz would act strange and when i rebooted, all changes i made to scripts and new devices were gone...
This was a card failing, but not fully failing, because when i put an backup back, the system would run for a while until it got to the cells with issues again and gave me trouble again...
so in my case not wearing out, but just bad memory cells on the card
I have a lua time script running in domoticz that triggers a switch 'On" to every node every minute.
the node replies by swtiching the id off again and counts how many times the host send a switch command, every 6 minutes the counter is checked, and in case lower than 5, a hard reset is done.
in domoticz I check if the off command is received and if the off command is not received for more than 3 minutes I trigger a switch "node alive" to off
as soon as the swtiching is received again, i put the "node alive" on again.
this way I can also visualize the uptime of the nodes in my network
when the" node alive" is off, some scripts are disabled because they have interactions between mysensor signals and other inputs, and the dependancies are not valid anymore as soon as the node is not alive anymore
if you run domoticz or an other home automation system, adding a time in bed script could be a next level
https://www.domoticz.com/forum/viewtopic.php?f=23&t=15502
in domoticz I have 2 lua scripts running for the HUE control, 1 time based and one triggered by the device change
next to that I have 1 watchdog script that switches on ID 100 to the node and the node will reply with an off at that ID so the node can be reset if there is no communication
a user variable has to be creased to store the current HUE settings (String)
a dummy text utility has to be created to store the HSV or RGB and dimmer values for the mysensor node to request
The device script contains calculations from HSV to RGB and RGB hex, I tried different formats for fowarding the data to the mysensor node and just kept it in the script in case I might need it later for troubleshooting
-- this script reads the setting of 1 HUE RGB device and forwards this to a mysensor RGB dimmer
-- one script will do this time based and the second script will do this on a device change, in order to capture changed made from domoticz and through the HUE bridge directly
-- HUE stores the values in HSV format where the mysensor node uses RGB values for the RGB LED's so these have to be converted before forwarding
-- a user variable has to be creased to store the current HUE settings (String)
-- a dummy text utility has to be created to store the HSV or RGB and dimmer values for the mysensor node to request
-- additional libraries for lua have to be installed

I have been annoyed by the high price of the HUE LED strips, we have a few HUE lamps at home and one led strip and would like more of the LED strips but not the retail price... The led strips are behind different cabinets in the living and we normally pick about the same color for them and we only set them once or twice a day, so I don't care about latency.
So my target was to make a cheap small copy of the HUE led strip with a wireless connection to domoticz that can copy over the colors of a HUE bulb or other LED strip.
Since I want it wireless mysensor seemed the most easy and since I already have a few other mysensor nodes.
To keep it wireless I decided to use a ESP unit and not a normal arduino with radio, just because of the size.
I made a small PCB with:
I use a CP2102 programmer to program the ESP unit with arduino IDE
and with a little 12V supply I can hook up any RGB LED strip
I have made 2 arduino scripts to control the LED's, one based on the fastled library and one just writing analog output values for the PWM signal
Only open now is to fade in and out when changing brightness, but the start of that is already in the script
the temperature sensor will detect if the unit overheats and will switch if off for 1 minute, if that happens 5 times the unit will go into deep sleep mode and you need to manually reset the unit
The fast led version I also tested with adafruit neopixels... only the small strips with 8 lixed LEDs flicker but the normal LED strip not so that seems not related to my control but to the LED's
In the fast led based arduino code for brightness adjustment I just manually set a percentage that matches on first sight

I run a mysensor gateway on an ESP8266 with some sensors directly connected to the gateway.
On the receiving end I have domoticz and sometimes it happens that the connection goes down and so I'm not sure of the state of the inputs of the mysensor node.
When the ESP reconnects to domoticz, domoticz also requests the version...
how to use this request to resend the current state of the inputs?
ip:192.168.2.200,mask:255.255.255.0,gw:192.168.2.254
.
starting server
Send sketch info
Present temperature sensor
Present heartbeat signal
Setup completed
0;0;3;0;9;Init complete, id=0, parent=0, distance=0
0;0;3;0;9;Client 0 connected
0;0;3;0;9;Client 0: 0;0;3;0;2;

0;0;3;0;9;Client 0: 0;0;3;0;18;PING
0;0;3;0;9;Client 0: 0;0;3;0;18;PING
in my sketch I like to catch the message Get Version to resend the input signals, since sending this right after starting the server is no use because domoticz is not yet listening....
like:
void receive(const MyMessage &message) {
if (message.???==Get Version){
debouncer.update();
value = debouncer.read();
send(msgOpen.set(value==HIGH ? 1 : 0));
....and so on
}
}
anyone any idea how to do this?
@TheoL you were inspiring! and at least made me enthousiastic to share more of my mysensor projects on this forum and pushed me to finish some of my open projects (in order to post them here)
My girl suggested to add an other workshop next time in a room next door... for the wifes/girlfriends/spouses : how to deal new projects or with a low wife approval factor projects 
Great event! thanks for organizing!
Although the experience of the attendents was various levels I think everybody had a great time.
Unfortunately I had to leave earlier than most people I had a great time and hope we can setup an other meeting for a next level work shop on my sensors.
your wiring diagram is not accessable:

It seems you don't belong here! You should probably sign in. Check out our Help Center and forums for help, or head back to home.
i use a DC motor so can't help with stepper motors, but can you share an image of how you setup your rails?
