Domoticz

Hi,

Noob to arduino here.

Currently working on a small project to get the aquarium into domoticz via arduino nano, starting with temperature, then gonna add on flow on the pump and such.

Getting readings on the temparture from a waterproof ds18b20, and started now on how to transmitt it using a 433 mhz china transmitter (you know the cheap ones ). But then it strook me, how can i send the data so that the RFLink Gateway and domoticz understand it. If i remember correctly the modulation on the transmitter is supported by RFlink.

Anyone here who has done something similiar? Or have a tip on how to transmitt the data so it doesnt get lost in translation ^^

hardware being used:
Temp sensor: http://www.ebay.com/itm/201544352532?_t ... EBIDX%3AIT
ArduinoNano
433 transmitter http://www.ebay.com/itm/5pcs-433Mhz-RF- ... Sw6EhUN9s-

The transmitter is fine. You need to use a script for your Nano that sends it with one of the known protocols.
I have some samples.. mail [email protected] for more info

Sweet, thanks in advance

HI, I would also need some sample script to understand how to transmit temp and door sensor states to Rflink through 433mhz cheap transmitter.
Thanks

Hello

I am looking for the exact same thing : door sensor state / temperature & eventually switch a relay.
Thank you for your support ( link to tuto...)
Have a nice day

French user got one great howto but in french language : http://easydomoticz.com/forum/viewtopic.php?f=7&t=1956

Works like a charme and battery friendly.

Looking at exactly the same here to control my floor heating pump (should only be running when there is temperature coming from the boiler through Domoticz, at the moment I have it running on a small PCB doing that but this can not be monitored) Switching the pump will be through a 'klik aan klik uit' switch.

Any chance to post the script here Stuntteam ?

Cheers,

Redmer

Did you consider using an ESP-8266 based board for this rather than an Arduino? This will transfer all data via WiFi, and is probably cheaper than an Arduino Nano + 433 MHZ module (I paid around 2 Euros for mine). After flashing it with the ESPeasy firmware, communication with Domoticz is set up in just a few clicks. I'm pretty sure it supports your sensor out of the box.

Looks like a very nice option.. also for making my washing machine start by wiring a contact parallel with the start button to make it start from Domoticz when my PV system is generating enough power to cover the power demand... Thanks !!

Can you make and guide about this ? Or is there allready one somwhere ?

I would start here:
http://www.letscontrolit.com/wiki/index.php/ESPEasy
It describes all possibilities and the different ESP versions that exist. You can buy them from e.g. EBay or AliExpress. Once you have it, you have to flash the ESPEasy firmware on it, this is also described on the Wiki. Here's a page that describes using it with a DS18b20:

It's not an out-of-the-box solution, but also not very difficult to build. Hope this info helps!
