Hello I would like to know if you can connect an lcd to the gateway, print in the lcd the value of a sensor connected to a node so that both the value on the domoticz lcd controller and the lcd. Do you give me an example? thank you all
Hi
This is a typical homer project in that I spend half an hour here and half an hour there so it moves very slowly!
What I have so far:
Plan for 10-15 zone heating control based on standard Y plan heating system. I need to generate control signals for:
Boiler on
DHW valve on
Heating valve on
*12-13 radiator valve heads (24v DC)
a) Domoticx setup based on a list of zones - the lua scripts are maybe 75% done and working so far - needs tweaks and tidying up before its shareable sensibly.
b) Battery powered sensor/ display node arduino based. Has dallas DS1820 temp sensor, 128 x 64 Oled display and three buttons using mysensors 2.4Ghz radio. It links with domoticz, displays (on demand) the room temp, setpoint and the buttons allow local control - boost/cut temp to xDeg for 1 hr. The sensor runs off 2 x AAA cells and takes 11uA standby with pulses of 25mA so could just run off a coin cell for 12-18months. The code is 80-90% complete but haven't started a PCB yet.
c) Dallas one wire sensors for some rooms where I am not bothering with a local display node. Also to be used for DHW and outside temperature for display/prediction.
d) Some 24vDC thermal actuators for the radiators - that's the biggy and now won't happen till next year and the heating is off. I also need to replace some valve bodies on some radiators so it will need (at least) a day off work at some point to do all the plumbing.
e) Android front end based on Netio - tried open remote but found that a bit long winded. This is 20% complete - just done 2 zones to prove the concept. This will drive a wall mounted tablet replacing the old room stat and also be the interface from my phone etc when away from home.
f) I haven't started boxing up the RPI - it needs a 24cDC 2-3 amp PSU for the radiator valves and wiring to all rooms - yuk!
This may wet your appetite but it is very much a work in progress and wouldn't make much sense if I published it yet. I'll post bits as they become meaningful - but its a way away yet.
If nothing else it tells you what's possible. That has taken me quite a bit of experiment to get this far.I've tried at least 5 different home automation packages and have now settled on Domoticz and Netio front end. At least - now I am on the implementation phase!

I had to get domoticz beta version to get scene/group available, can't remember what version I had previously.
Anyway group is exactly what I wanted ....
Do some debug on the node and on gateway and check if data is actually sent from the node and received by gateway. Also use wait instead of sleep if you are using it as a repeater and relay actuator.
Good to know, indeed my setup is working now with stable libraries thanks to this helpful community.
I'll go back later to development libraries to see if I'm able to work with it as well.
@esfnl said in RPi 3 with Domoticz and RF-link (RFXcom) 'TSP-fail':
MySensors is supported
MySensors is supported if you connect an NRF24 to the RFXCom as instructed in the link, did you ?
As explained, it can only receive information, so as you seem to have no gateway to assign node ID you will need to define your nodes as passive nodes and hard code node id :
#define MY_PASSIVE_NODE
#define MY_NODE_ID 2
#define MY_PARENT_NODE_IS_STATIC
#define MY_PARENT_NODE_ID 0
