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

RE: About the relays
@barnabás-králik said in 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]
@David said in WiFi instead NIC [Mervis]:
Hi @Havor,
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.

Copy protection
Just wondering, is there a way to have a copy protection to protect the process parameters you made in Mervis, from people easily copying what you created.

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
Hi @tomas_hora
Any answers/suggestions on what type of controller I should use?
-
RE: Mervis & Stepper motor
@tomas_hora
Hi TomasWhat 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.

RE: Mervis & Stepper motor
@tomas_hora
Sorry, I did not see your reply, so I was thinking it could not be done.Here is what I wane do:
I wane use the UniPi also as a feeding computer, that can control the amount plant nutrients, in our greenhouse.
I wane control 5 peristaltic pumps with 12v Steppermotors, 1 big peristaltic pump, that pumps 5 ~ 900 ml/min water, and 4 small peristaltic pumps 0 ~ 25 ml/min, that add the nutrients to the water (I need to ad 0.25 to 3ml/L of different type of nutrients), where they get mixed and then distributed by hoses and controlled solenoid valves to the plants.
Peristaltic pump:
I would like use this board to drive the stepper motors, as it is a very affordable solution.
And it comes whit this software to control the stepper controller, but it I think that software is not easily gone work whit UniPi.With most other solution is also using a Windows driver, so I am up for any other controller solution, if you have any affordable recommendations, I only need to control the rpm's, the 4 small pumps uses 0.75A and the big one 1.8A with both in a 12 or 24V current version.
Is there a way to this with MERVIS, or one with one of the other software solutions supported by UniPi?
For information, here is what I also wane do with the UniPi for determining the best software solution:
I also wane measure the soil moister content whit this sensor, to adjust the amount of watering.
(there is also a RS485 version for if I wane use L503 Neuron, and the maker is also thinking/developing a 1wire version)Next, to that, I wane control some relays, led drivers and a fan, both with 0~10V, and 1wire U1WTVS and a temp sensor for the water temperature.
I also wane make a weekly feeding schedule, where the amount and/or type of nutrients gets auto adjusted as the vegetables grow.

RE: How long are the UniPi 1.1 and its Extension modules gone be supported
@skorp said in How long are the UniPi 1.1 and its Extension modules gone be supported:
8 channel expander has really small number of selling, we will make Neuron S100 with 2 channels, which should be enough for the major part of our customers.
Would you not consider a Expander unit, ware you can hookup the 4 remaining wires of the RJ45 to be used as free power lines?
Like a 12V + 24V, 5V + 12V or 2x 5V/12V/24V, to power 1Wire sensors and devises, then you don't need of running extra power wires if they need extra power.
Would be handy for things like steering a remote relay whit a DS2405.
Tho i don't know if the 1Wire hub can handle those power lines.

How long are the UniPi 1.1 and its Extension modules gone be supported
Short question, how long are the UniPi 1.1 and its 3 extension modules gone be supported.
As i see in the shop both the 4-AO 0-10V extension and the 8channel 1Wire expander have both less the 5 in stock, are these outgoing products, or are they they bin ordered new?
Or are they gone be replaced by more expensive Neuron parts?

Bigger relais board
Would UniPi consider building a b bigger relays board?
If you would use these small 8A relays (1x NO €0.77), you could fit about 32 relays on one extension board the size of a UniPi board holder.
I think that most people that need many relays, only need 1x NO relay to use for steering valves or DIN rail relays and so on.

Mervis & Stepper motor
Is it possible to control from Mervis a Stepper motor, and if yes whats the recommended way of doing it, Modbus, I²C?
I want to control 4 small stepper motors.

RE: Lots of documentation missing
@tomas_hora said in Lots of documentation missing:
You could make a demo for every part on the software you like to use.
And send a demo package whit All the parts to different software developers that are willing to also make a review and demo hoe to use it whit there platform, as hoe grate the hardware May be whitout software support its useless. -
RE: Lots of documentation missing
I still dont see any documentation on how to do a software setup of the different software solutions that could be running on the UniPi.
If you really want this hardware to go mainstream, you should at least have some how-to video's on how to setup the different software solutions, as of now i don't dare to to buy a UniPi, as i don't know if i be able to set it up.
The same go's for the AddOn boards, jst have video's how to install the AddOn boards in the software, and a basic over view of how to work them.
In mine example, i wane use Domoticz as a platform, probably most non nerd users wane use that software, to do some home automation.
I wane control:
- A couple of mean well LED drivers 0-10v or PWM.
A couple of radiator thermostats drivers for the central heating 0-10v.
A house fan also 0-10v or PWM.
Some relays for light switches.
Some one wire sensors
I started looking at UniPi, as it got all i want on the the hardware side, but after looking at it more and more, the software is just not documented enough for me to spend €400~500 on UniPi hardware, that i maybe never be able to use.
- A couple of mean well LED drivers 0-10v or PWM.

RE: 4AO extension and PWM for dimmable LED driver
Hi i have a MeanWell led power supply that can be controlled in 3 ways.
@1r4uc702:
Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance.Can i use one of the 12 the PWM open collectors from the 4AO to dim the LED PSU, or do i need to use the 0~10V analog signal?
