My First version of curtain control Node is ready, installed and tested. Some work is pending, which I'll complete on my weekend.
Edit: Code for the Node:Curtain Node
Curtain Control Node.

Please share your feedback so that I can improvise.

@mfalkvidd Thanks for your suggestion. It works great.

Can I use i2c EEPROM for OTA bootloading with DualOptiboot or it has to be Serial SPI. I was not able to find any documentation on it. I brought a breakout board and it seems to be i2c, and i2c chips are easily available where I live.

Its a Geared DC Motor with Voltage Rating of 6-12V and 100 RPM. I am using a L239 to control the motor.

Thanks @mfalkvidd and @gohan . That helped.

@ahmedadelhosni Hey, I found this article. Seems like the guy has used i2c for remote flash. I was not able to extactly understand whats going on, maybe you can help.

@franzelare Great. Good Luck with the build.

I'll be posting my HW design and Code as part of Contest on openhardware.io

@mfalkvidd I have hit a dead end. The issue described in the thread is stii not resolved. Any advice on what can help figure out the issue would be helpful.

Thanks

Any Moderator or Admin here who can help me, please.

@rejoe2 I am using 2.2.0 on both gateway and node. Using NRF24L01+ with Caps . Strangely one of my node running on 2.1.0 is able to communicate with the gateway. Let's hope Mods have some answers. Appreciate your efforts and time.
Thanks

@rejoe2 I have already tried 2 different RF modules, the known good ones. So RF can be ruled out. I am running it with Domoticz, usually I don't have to change any setting, on presentation the node is shown in Domoticz and I just add it to my UI. Also tried the option Allow discovery for 5 mins in Domoticz that did not work either. So kind of lost here as to what's happening.

@rejoe2 I tried as suggested. Cleared EEPROM using the sketch from MySensors example folder, tried auto ID assignment and also predefined ID. None seems to work.

This is the log when no ID is assigned.

Please advice if there anything that could help me understand the issue and fix it.
Thanks alot.

@rejoe2 Will try that. I did tried assigning ID manually, but that did not work.

@rejoe2 oh, I am sorry. I use the sketch from EEPROM Lib in Arduino. Not from MySensors. I am doing it right?

@rejoe2 I have used the Mockmysensor example sketch from Mysensors.

I updated the gateway to 2.2.0. I have one sensor on 2.1.1 which able to communicate fine with my gateway. I tried testing a node on 2.2.0. I flash the MockMySensor sketch, but its not able to get a node ID from gateway. I also cleared EEPROM and replashed , tied to assign ID to node but did not help. The ID:4 we see in the gateway log is my node running on 2.1.1. Need help in understanding what could be the issue/fix. Thanks
