Hardware

So nobody has done it yet? What about mosfets? Can the same schematics be used as with led strips? But how to limit the power fed to crees?

@mfalkvidd Oh! Yes thank you very much. The fact is that a typo in the description of the product I bought (838 != 868) is what confused me. Now thanks to you I realized it. I'll stick with 868 and see if I can work with it. I live near a frontier with Portugal and those guys here doesn't care about pirate radio emissions and I get strong interferences in radio, wifi and over all 2.4ghz. 433mhz even doesn't have more than 2-3mt of range for me. 2.4ghz only around 7mt @ sight. Bluetooth headphones have dropouts even carrying the phone with you. All of this living in the country. It's very annoying.

Thanks both. I will try the gateway with version 2.2.0 first.

@sola yes, you are correct that the calculation is form2xAA. See the comment inside loop() on the example at https://www.mysensors.org/build/battery for the required calculation, and this part for the voltage divider: The ADC is set to use the internal reference value of 1.1V - so Vmax at ADCmax = 1.1*(16+4703)/4703 = 3.44V You'll need to change the resistors in the voltage divider to handle voltages as high as 8V.

can you login to the mqtt server with any mqtt client for computer (like mqtt spy or similar)?

@Anticimex @tbowmo an #ifndef made it work and sketch compiled.

It is possible to use RFM69 radio via SoftSPI which allow to build gateway with W5100 or ethernet shield. You need to change RFM69 driver and MyConfig.h configuration file. I put modified these files at github repository: https://github.com/gieemek/RFM69_softSPI-for-MySensors-2.1.1 You can find instruction how to prepare gateway sketch at this repository too. My gateway (as MQTT client) with ethernet shield and RFM69 radio via SoftSPI is working for 10 days without any problems.

nice... i got this reset stack now: CO2 level: -10 ppm Soft WDT reset ctx: cont sp: 3ffef1f0 end: 3ffef3d0 offset: 01b0 stack>>> 3ffef3a0: 00000000 00000000 00000001 40202281 3ffef3b0: 3fffdad0 00000000 3ffee39c 402022ac 3ffef3c0: feefeffe feefeffe 3ffee3b0 40100114 <<<stack<<< ?⸮⸮⸮⸮DH⸮⸮⸮CO2 level: 395 ppm CO2 level: 395 ppm CO2 level: -10 ppm CO2 level: 405 ppm CO2 level: 405 ppm ...

@Ron said in 433MHz Transmitter FS1000A stops working when connecting antenna: I could try it with a cable of length 170mm but I am not sure if that is anything >else than with the antenna. Yes you should experiment to see. That is the best way to find solutions when you are a "Maker" Does the transmitter also needs more voltage when an antenna is connected? Sorry I am not an RF engineer so am not sure on that, although I would have thought you would achieve best results with an antenna of the correct length connected. As i said previously I know they work better with a higher voltage. From memory (you should check) I think they are good up to 12v At the moment i just connected it to the 5V output of the arduino. Maybe that is >too low for the transmitter with antenna. You should use a multimeter to check the actual voltage. The clone arduino's are sometimes prone to be a bit low on their 5v line as are some computer usb ports, especially if you have a few other devices (keyboard , mouse, speakers etc.) connected as well. Power problems are a common source for causing trouble I always try and power my nodes from a dedicated supply to eliminate this issue. I ordered some boost converter to test with higher voltage. Maybe that helps a >bit :) Your simplest solution may be to power the test node from a 9v battery. You can supply 9v directly to the arduino VIN pin and also 9v directly to the FS1000 power pin instead of the 5v line. This will at least let you know if it is a power issue. It is also not unusual for these type of remotes to fire off a burst of on or off signals instead of just one transmission. This gives them a better chance of getting the message through. So if you are not doing that already you could try sending a few times separated by around a 10 ms delay. You may need to experiment a bit to see what works best. I know one remote I was working with sent the message 6 times separated by 13 ms.

Separately from this, you can find a local 3d-printing service on 3dhubs.com - I found one local to me this way, who did my first print, which got me onto the 3d trail (I subsequently bought a Prusa i3 MkII kit).

@d00616 Curious when these might be available for purchase. I like this idea.

@mtiutiu I also assumed that I can spell and proofread. Thank you for this info. It is more helpul than a month of reading google translated russian sites about livolo.

I can't help much, I always used ethernet GW or MQTT as to me are much better

@javizzz Great work so far! I was looking at doing similar and using a RFM69 instead. I had taken a few days off next week to get stuck in. I was thinking I might use a small battery LiPo that I could charge from the AC side. Your work is a huge head start. Thanks!

That's why I bought shielded modules

@Technovation Welcome to the MySensors forum! This is an awesome first post! :+1: Hope to see a lot more in the future! :yum:

@Yveaux Works perfect now, thanks. Now I just need to research calling this as a transaction. Just brainstorming a bit, I will most likely have a function written to grab the value from the sensorand begin and end the transaction there, but since I have never worked with transactions, I will need to research how to write the code to do that.

@zboblamont Thanks for the advice. I have been looking for a circuit diagram of the sensor to determine how adjusting it could change the beam. I would love if the beam was not as wide.

Is any of this code archived someplace? Any direction to get started? I want to shut off my tv via Vera Edge.
