💬 Wall Socket Insertable Node

when can we buy your pcb's ?
@Cliff-Karlsson Custom transformers samples have been produced. I hope to receive completed devices samples in two weeks.
-
Unfortunately everything that could go wrong went wrong.
So sample transformers are ready, sample boards are ready too. But I am expecting package with all my new boards and components only next week and hope to start testing soon.

Hi, will it also measure voltage or just current? Because to calculate power you need voltage as well? Is it possible to add dht22 and one wire temperature sensor to it as well, then it could replace all the temperature controllers for heating cables.

Hello. RFM69 module has built-in temperature sensor. If you look on the board carefully you will find a lot if arduino pins. You can use it for any sensors if it is critical for you.
What controllers are you referencing to?
About voltage... I think you know voltage in your sockets without any sensors with enough accuracy :smiley:Boards and components are under customs clearance now... Expecting :)

Check out this interesting topic on accursy for power measurement:
GregDo you have data on the inbuilt temperature sensor?
Frankly speaking I had added current sensor last night before test board production and I had no goal to measure power very accurate. The main goal of this sensor is ability to check fact of load (forget iron for example :)). Of course I can improve it in further versions, but it is not the main feature now.
I tested this temperature sensor and it works fine. I'am not sure mysensors library supports it. If it doesn't support it I will try to add this ability after hardware testing.

@Koresh Ok, I am looking forward to hear how your board turns out. So what I am looking for is something to replace this temperature controller. I was thinking about using esp8266 wifi chip instead of the radio, since power is not a big issue since its connected to the power line. Then people like my parents can use it with IFTTT and do not have to add a gateway. I was also thinking about adding a connector for a nextion display, just in case you want to display the temperature, use it as input to set temperature etc. It should also have a better temperature and humidity chip then the one inbuilt I think. Screw terminal to connect floor temperature sensor. Measure power accurately. Well if you would like to cooperate on version2 of your board let me know. I would like to make 20 units or so for now.

And some photos after soldering of the main components and slight washing.
Relay trick :)

Hi Koresh. Interesting project ! Are you planning to sell some assembled parts too ?
-
I just bumped into these too:
https://www.openhardware.io/view/102/Wall-Switch-Insertable-Node#tabs-instructions
So interesting ! will these be sold too ? -

I will make a small presentation of new boards tomorrow in Breda. Of course I will try to start mass production asap :) You can check estimated prices of all boards in button size radionode thread. -
Hi, it's a very intersting project but what about the protections of the switching power supply ?
I see a varistor but neither fuse nor Thermal Cutoffs.

@tonnerre33 do not worry. It will be in final version + we can use temperature sensor in rfm modult to switch of the relay.

Very nice to see this device today live in Breda ;-)
-
Very nice project. Looking forward to buy it. It would be nice to have possibility to trigger switch via local button (as in Fibaro) and not only via radio. It's possible from software point of view but board should be modified slightly. Is it in your todo list @Koresh?
