If you are handy, and make new hole's could you also replace your Pi your self?

RE: About the relays
I'm thinking about using an L403 for controlling a large number of blinds (apart from other building automation duties) with 2 relays per blind motor.
Why not go for TCP-IP solution, i use a Kincony kc868-h32, a 32 relay solution, that you can steer the relays true a url link command, works fine for me.
There are similar solutions more hobby orientated, and more pro, over Modbus, serial and TCP-IP, there are also 2/4/8/16 solutions out there, so that you can have your relays close by what you wane control, and only have to run a network or serial cable to the relay unit.
A Bulletin Board for Recruiting/Hire/advertise a Software Developer
Could UniPi ad A builtin board for recruiting/hire/advertise a software developer.
I think many people that wane use a UniPi for there project, and see the benefits of the UniPi devices, but lack (some/all) the skills to complete the project they wane use it for.
- It could be they have no or very limited skills, and need a lot of help.
- It could be that they have the skills but need some help (but more then the SW Q&A could solve) whit a problem they are having.
- It could be that they have just need for extra manpower to finish a project on time.
My suggestion would be to have two sections with the same sup sections as in SW Q&A, one ware coders/developers advertise the skills, and one ware people can ask for coders/developers.
It would also be nice if a section for reviews would be added to the profile's.
RE: WiFi instead NIC [Mervis]
I do not understand the relationship between a surge protector and wifi settings?
iVar wants to use WiFi because he fears that he will blow up R-Pi with a power search true his network connect, so instead of paying for a wifi adapter and using less reliable and less secure wifi, he can also use a search protector to isolate his Neuron that way from lighting.
A different approach to the same problem, I got Eaton search protectors, cost €16 per power + network connection.
RE: WiFi instead NIC [Mervis]
Why not just use a search protector, I live in Norway, and where I live we have also lots of problems with lichting, and have before all my electronics a search protector, eider a power brick or a UPS.
Many of them also have network search protection.
Would UniPi not consider, switching over to ODROID-C2 from RP3 as their central unit?
Or at least consider it as an upgrade option, it's only €10 extra, but the eMMC modules would also cost more than a SD.
The ODROID-C2 is mostly a Korean improved RP3 clone.
I was thinking it myself, but also hear from many people, microSD cards are not really the most reliable storage solution for a PLC type of devices, so a move to eMMC, would not really be a bad one.
- It's 25% faster, always nice, but we properly not need it.
- Gbit networking dedicated true CPU not true USB as on the RP3.
- 2GB RAM
- An extra SD slot for back-up/failover or extra storage, and can be used to upload to eMMC card.
- But above all, it has the much more reliable eMMC5.0 storage option, with a nice speed upgrade.(1).
- Runs standard Linux, instead of Raspbian, so you can use more standard Linux device drivers, like USB RSxxx dongles, and maybe better support for Domotica like software?
- And is pin and mostly hardware, and layout compatible whit the RP3, so it could be implemented whit minimum effort.
- Downside, it's got no BT or WiFi, but that could easily be fixed with €10 USB dongle(2), if people really needed it.
It would be nice to hear what others think of this.
(1) eMMC5.0 is something really desirable from a reliability standpoint, as eMMMC5.0 has a real SSD controller (light version from SATA), mutch better I/O performance, and fewer problems whit write amplification, that could crash your storage over time.
(2) Could also be sold true your website.
p.s. your spam filter is really aggressive, and blocks you if you edit your post more than 2 times in one row.
RE: Mervis & Stepper motor
What type of controller works best with Mervis? 1 on 1 direct steering, semi-direct or pre-programmed?
Would something like this Mitsubishi PLC work in slave mode, and would it be more or less plug and play in Mervis, or would I need a other solution?
I think that I would have no real problems whit Mervis itself, but if setting up requires a high-level knowledge of protocols it will get hard for me.
