Sunrom Dimmer 1289

Hi
I have just been researching for a new projects and came across this site that has been invaluable.
It has reignited my passion for this side of my life and hope to build a few cool projects with my son.
Down to my question a project I would like to work on is dimming an incandescent 100w - 150w lights. I see there are a number of dimmer solutions however no one seems to have used the sunrom 1289 dimmer module.

Is this a possible solution or am I missing something simple?
Again thanks for such an inspiring site that makes such an exciting advancement in technology available to so many.
No doubt you will hear a lot from us and I hope to share some of our experiences and contribute as much as we can.

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

@skywatch said in Awesome tip: run LinuxFX instead of Windows!: @NeverDie Thanks - Interestingly they show a free version on their site still. Did they revert due to bad publicity? https://www.linuxfx.org/ I stopped following it, but I seem to recollect that the free version was noticeably missing things--otherwise, who'd buy the paid-for version? Anyway, its standing on Distro-watch has fallen considerably. It may seem unfair to niche distros, but I think it's generally better to stick with the more popular distros, unless you have good reason to choose otherwise.

Some humidity sensors are known to lose accuracy with age. For instance, the Si7021 is known to have this problem. If that matters to you, then the best choice is to pick sensors that have datasheets and which have specs as to their expected longevity or accuracy over time. Then buy from mouser/digikey to be certain you're getting the real thing rather than factory rejects or counterfeits. For extra insurance, I avoid electrolytic capacitors entirely whenever possible. I buy only 7XR rated ceramic capacitors that are overspec'd. The difference in price is small compared to a failure down the road.

It has been a long time but I’ve learned a few things that I wanted to share. This library of information (Thank you NeverDie and others) has been so helpful in my hobby developments. Software Defined Radios for signal analysis. With the help of Andreas Spiess explanation of IQ transformations, I learned about Software Defined Radios and I bought one (RTL-SDR). Using this I can clearly discriminate between effective 433 MHz transmitters and bad ones. Not only is the signal density displayed on the software (SDR#) but so is the frequency. Power Profiler Kit II has been indispensable in watching power usage and seeing into the details of the radio transmission. In effect this thing has saved me from buying an oscilloscope for my simple little bench. Tonight, I saw this video: https://www.youtube.com/watch?v=Z9nycymUd-I It describes common PCB errors. It is too advanced for me, but I did pick-up a few ideas about ground planes (tip #6 from the video). I hope this is of some value for folks.

After re-installing the previous 32bit raspbian version, the gateway seems to work ok. It seems to me there is a problem with the 64bit version.
