Domoticz

Sorry about the late reply Matt, I have been busy. The temp sensors are on a single ESP12 node mcu board powered by a mains 5v PSU. Effectively, if the fridge mains goes off, all 3 sensors go off, so no need for a battery supply. It's been stable for a while now. 947539730 : DS : Temperature: 36.50 ...

I agree with the Dallas Sensors and ESPEasy, I use a NodeMCU with 3 Dallas Sensors, One Central Heating, One Hot Water
and One In the Fridge, (I had a problem with defrosting for no reason).

Cheap and cheerful, upgradable to more sensors if required, and so much fun to play with.

I didn't know that led*, thanks , will look for it.

Hence when I said about the pinch of salt, I meant it

NickHead

I have just had a look at ESP Easy and I don't think it is possible to integrate the Nextion. It looks as though it has standard routines for the devices. There is no way of managing the data that is received and then putting it out to the Nextion. It looks like it's fixed software, what is has in ...

no problem ayasystems, I was just thinking of an easier route really, MQTT is already part of Domoticz with hardly any overheads like with http and json commands. I know 'cos I have used it and on a system like mine it does drag the system down to a point that lighting and control is delayed, hence ...

Looking good.. Thankz Derik, Just a Mega 2560, Nextion 2.8" and a Arduino Network Shield with a LOT of programming. There is a Raspberry Pi as a MQTT Broker on my system taking the Data from another Rapberry Pi running Domoticz. There are various ESP 8266's sending temperatures about the house. As ...

NickHead

Like I said, and you actually didn't answer.

Use MQTT, here is another one on the same network.

The first ever one I built to test. Not with Nextion though.

This is what I have up to now.

Controlled by my Arduino Mega 2560 but I am now going over to a Raspberry Pi 3 as I am running out of memory.

Use MQTT. One transmitter to many receivers, does not load the system.

I use it in my Nextion Setup and have control over virtually everything .

Code: Select all

from time import sleep

import pifacedigitalio

pifacedigitalio.init()

pifacedigital = pifacedigitalio.PiFaceDigital()

pifacedigital.leds[7].toggle()

sleep(0.5)

pifacedigital.leds[7].toggle()

try running this on the pi and see if it kickstarts the piface

P.S. It is a python script

NickHead

I use a Raspberry Pi with a PiFace for my Home & solar measurements. The PiFace takes the readings from the flashing leds (1000 impulses /kw). I also read the RS422 Data from the inverters and convert with python to show more info and double check the impulse readings. You have to separate the ...

NickHead

I have been thinking of this one. If this was my system, I would use Realterm, a communications terminal, to connect to the Amp on the IP and port itself, using the Telnet section of the program. Run the program and see if it is actually connecting, or has a channel/socket to each other. I know it ...

NickHead

if you can PM me, dont know wether its on, then send me an email and i'll send you the file.

should be in order then

gnite

NickHead

Sorry

if Dstart != "P":
goes directly under global DSTART

all in the same line other then DSTART = (s.recv(1))

I am Soooo tired now, so off to bed, will try again tomorrow
making too many errors now, I have been at work and knackud

NickHead

if there is a colon (:) then there is an indentation on the NEXT line

Python Program Rules

NickHead

if Dstart != "P":
goes directly under DSTART == "WON"

all in the same line other then DSTART = (s.recv(1))

NickHead

wont let me do it for some reason

NickHead

i'll attach it as a file

NickHead

Code: Select all

def ReceiveData():
	global DStart
    	while DStart != "P":
  		DStart = (s.recv(1))		# Wait for a response "Pxxx"
     	DStart = (s.recv(3))			# Get next 3 characters
	if DStart == "WON":

Should look like that
If its the same when i press enter

and it isnt

NickHead

yer, python has to be perfect on indentations

maybe the cut/paste messed it up
