Scene Controller

[alexsh1]

Bringing back this old thread as I am building the scene controller now.
I am having a problem with a lot of garbage like this:

send: 7-7-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=ok:0
send: 7-7-0-0 s=255,c=0,t=17,pt=0,l=5,sg=0,st=ok:1.5.2
send: 7-7-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
read and drop: 7-7-0 s=255,c=3,t=6,pt=1,l=1,sg=0:0
read and drop: 0-224-0 s=0,c=0,t=0,pt=0,l=0,sg=0:
ver mismatch
read and drop: 0-224-0 s=0,c=0,t=0,pt=0,l=0,sg=0:
ver mismatch
.....
goes on and on

I do not have different MySensors GW/nodes. All of my GW/Nodes have MYS 1.5.2 Where does ver mismatch come from? Also time is not getting pulled into the scene controller from the controller (Domoticz).
Cannot get time from the controller either...

OK, just to revive this project, I decided to modify it as follows:

This would make the transmitter fit between the screen and the adapter

The problem is that this sandwich is super thick. So I got a new screen from itead studio, which can be used without the adapter. In this photo I desoldered D14-D21 pins as they are not used in order to hook up nrf24l01+:

This is a semi finished project. The power is fed via ICSP through 662k (under the red tape):

Now I need to isolate everything:

This is how Mega + the screen looks:

Now I need to figure out how to stick the battery between the screen and Mega :)
Any suggestions welcome!

Additionally, I have recently received a new Enhanced Nextion screen (again from Itead Studio) and a new ESP8266 PCB:

Much thinner :-) so watch this space....

@alexsh1
cool ;) I made one like this some time ago https://forum.mysensors.org/topic/2766/an-esp8266-nextion-scene-controller/5
but it's not with the new nextion rev. i like these hmi screens, easy to use.

@scalz Yeah, I saw your post a few months ago and it made me think seriously about getting my hands dirty with ESP8266. I have just started so do not expect to come up with anything fully working tomorrow as there are many peculiarities concerning ESP8266 from firmware to programming.

You have fully finished integration of your thermostat/scene controller with the controller?
Are you using Domoticz?

[scalz]

@alexsh1 i'm using mqtt and jeedom for this (jeedom has plugin for thermostat etc..) and i have another board which does energy monitoring+heater management. just for curiosity, i have enough pcb lol, but where did you buy your pcb for nextion? or maybe you did it?

[alexsh1]

@scalz I am not that smart yet to design my own boards. Having said that I have made a good progress on C++ and MySensors over a year. So designing my own PCB is a next logical step.
The problem is that my home has been fully automated. I have to challenge myself with a more difficult projects or move on to automate my neighbours house lol :-)
The most difficult part though is finding the right case. Printing on 3D printer is not cheap as I do not have one and finding something of the shelf is literally impossible.

Talking about the PCB, I took the one design by
Peter and Aidan:

However, I'm redesigning the software part to make it a multi functioning scene controller for Domoticz.

A small teaser - quick menu. One has to be a graphic designer to get the menu nailed.

This is still in an alpha state and ESP8266 development may take some time.

This is a TFT screen with the daughter board:
