Honeywell Round Wifi+Synology NAS

[TheChief]

Hi all,

I installed with succes Domoticz on my DS214SE.
I was first planning to buy a raspberry PI and use it with Domoticz to first control my central heating system.

I'm from the Netherlands and my electric/gas company is taken over by an other company (EON -> Eneco). At this moment im
using a gateway with thermostat from Fifthplay, it also monitors my gas and electric use with sensors on both meters.
The support for online control of my thermostat and to my use of gas/electric stops in a few weeks because Eneco has his own
system.... I asked Fifitplay if its possible to keep the system running, its possible but will cost me 80,- euro.

I was planning to go use Domoticz for a long time and I would rather spend my money on a system that is more possible with!

Some questions;
-Is it possible to connect the Honeywell Round Wifi to my synology NAS? Do i need a cable or a rfxcom?

-I work in shifts, a cycle of 10 weeks, 2 early, 2 late and 2 night. In my curent system i can only make a program for 7 days.
Is its possible to make a program in Domoticz for my kind of schedule??

-Whats better, Synology+Domoticz OR Raspberry+Domoticz?

-Any other tips?

Thanks in advance!

Great post! I didn’t knowral of these resources and I’m going to go check them out now!

After testing Domoticz on my Synology i came to the conclusion that Raspberry PI is a better option for me.
So i bought one last week, its works great! Did install some plugins and looks very good!

If managed to connect the Honeywell Round Connected Modulation to Domoticz (Evohome true Web API).
I get the temperature and can adjust it manually.
But f i want to set timmers i can only choose for on/off, no option to put in a specific temperature?!

Any ideas?

Hai Chief,
Interesting project you have.

Can you tell me how you managed to connect the Honeywell?
I have a Remeha eBase communicating with a remote station and would like to control it via Domoticz as well.

Thanks.

Just add the "Evohome via Web API" by going to settings ---> Hardware
See the screenshot attached. I used my login from honewell to control the thermostat.

Domoticz on Synology will eventually frustrate you. The OS is a very stripped Linux variant with no build environment. That can be a real pain if you do any external scripting in perl or python. I have a 'big' Synology (DS916+ with 8GB) but I don't use it for Domoticz for that reason. You basically want a full-blown Linux OS to do home automation. A Raspberry will do fine but if you want to avoid SD card woes then I'd recommend an Intel NUC. I have one with a small SSD and 4GB of RAM and it works really nicely with Domoticz. Total costs around EUR220. I chose Ubuntu as my OS it's very well supported in the Linux community. But the Pi will do fine too if you can live with SD cards. Just don't get a pi-zero as that is like 20x slower than a pi-3.

Use JSON commands to control the parameters you want - it's documented in the wiki. The syntax looks like this:

Code: Select all

http://192.168.1.12:8080/json.htm?type=setused&idx=106&setpoint=22&mode=TemporaryOverride&used=true

Use that as the ON action of the switch you set a timer for, and in the OFF action use the same syntax but with a temp of 16 or whatever. The idx value for the zone in question will be in your devices list. You can also specify an &until= with an ISO date-time if you like but that's not easy to specify in a switch-action field.
