Perhaps my definition about "controller", is a bit broad here. What could be done, is to have a thin "controller", that receives MQTT from the existing gateway, hands out IDs if they are requested from a new node, and translate the message into homie compliant topics. That is all it has to do, should not care about the rest of the automation at all. Should also be able to translate back from homie compliant to mysensors. This could be written in python, c#, javascript, rust etc. The benefit is that you have (relatively) easy editing of configurations at hands, without re-uploading sketches to your gateways / nodes, if you decide that node X should be named Y instead. And I am in no way trying to treat anyone as a fool!

@NeverDie I have two of them and made some applications using PlatformIO IDE. I like the Wio Terminal. The only issue that I experienced until now is that I couldn't get one of my apps, which is repeatedly posting sensor data to Azure Storage Tables, running without hangs for longer time periods. If you can live with the watchdog it is useable. I didn't try the bluetooth and sd-card functions. A good thing is that you can easily enable debugging with a little bit soldering and a J-link debugger.

@hek From what I've read, to better avoid browser fingerprinting, Brave apparently camouflages itself as Chrome: https://www.ctrl.blog/entry/brave-user-agent-detection.html That would make sense, since there would be less uniqueness if mixed into a larger pool, and Chrome has the largest pool by far. Perhaps that would mean you'd be getting tips from seemingly "out of the blue". Brave is pretty new, but there's a good chance the idea might catch on when people realize it works in their best interests.

Ah crikey, you're right there. Thanks @mfalkvidd, time to dust off the soldering iron. Cheers

@NeverDie said in Advisory: put IOT devices on a separate LAN/vLAN for better security: @monte https://www.ebay.com/itm/X10SLH-N6-ST031-Supermicro-E3-1200-v3-LGA1150-Motherboard-3x-X540-T2-6x-10GbE/184546263249?hash=item2af7d080d1:g:CCUAAOSwoP1gSWhO Lest I mislead anyone, I subsequently contacted to the seller and, despite the wording, it doesn't include an E3-1200 with the board. He just meant that as shorthand to refer to the processor family that's compatible with the board. That said, there are a ton of inexpensive used LGA1150 CPU's on ebay that could serve the purpose.

@Martin_Smith Microwave backscatter can show rain out to some distance. At airports an optical method is used as it also covers fog and snow. It really comes down to why you want to measure distance in rainy days and what sort of distance you intend or need to cover.....

@Eilleesy I suggest you post your code and any error messages you get. A link to the library you want to use might also be useful.

@Westie That feature can also be used with the Arduino Nano, or any other ATmega328P-based board. I had NRF24 + RFM69 running for a couple of days using a Nano as an Ethernet MQTT gateway and it worked fine as far as I remember.

Reporting back: I installed the Gen2 Emporia Vue, and it "just works" on the first try. Ironically, it reports the same amount of power for my refrigerator as the far less expensive TopGreener power module, so I guess the TopGreener is more accurate than what I had thought. At least the Emporia Vue's built in graphing is far superior and involves no switching, so overall I'm glad I made the upgrade. :-)

@Jasonkeel The green is the flex PCB,, as you can se how it' turn 90degree a few times[image: 1616522947005-screenshot-from-2021-03-23-19-08-12.png]

@Julie-Adam Have you considered disconnecting the air-line from the controller and reconnecting it to the air-head ? The cranium woodframe is probably interrupting signals which possibly explains the coupon fascination...

Were you able to find a resolution to this problem? I'm getting a similar issue.

Ok, could not find the root cause for why the embedded forum thread on openhardware.io couldn't detect if user has a valid session/is logged in to the forum. Did a workaround by adding a "Comment" button which redirect user to the thread on the forum.

@skywatch There is also the next "Yet another Arduino with fancy hardware but poor library support" planned: Arduino Nano RP2040 Connect [image: arduino_nano_rp2040_connect-1024x576.png]

Couple of things to think about with capacitors. With electrolytic caps there ESR ( Equivalent Series Resistance) is quite high if you need a lower ESR try going for a polymer electrolytic. Ceramic capacitors, as previously said don’t go for a capacitor that is rated at the same voltage, in my experience at least 1.5 to 3 times the max voltage your working with. So if your working with 5V I would go with a 16V part. The reason for this is the DC BIAS of ceramic capacitors, if you need 1uF of capacitance and use a 6.3V cap the DC BIAS of the capacitor could only 20% to 30% of the stated capacitance. Therefore you would need 3 or 4 capacitors at 6.3V to get the correct capacitance where as with a 16V part you may only need 2 capacitors in parallel to achieve the correct capacitance. Most good capacitor manufactures will have these online in the specifications area of there website. Also be careful depending on the power supply your using they may need electrolytic as the ESR of ceramics is very low and this can cause the power supply to become unstable as the control loop of the power supply can’t cope. These are lessons learned over the years as I alway say you learn more from making a mistake than being told what to do and getting it correct 100% of the time.

@zboblamont & @mfalkvidd - Thank you for that. It never occured to me that rounding might need some help. But now it makes logical sense. @mfalkvidd I guess if you used 'bankers rounding' you would always end up with 0.
