This all sounds very good! Impressive progress!
Will it be possible to stop the blinking colon on the clock?
Thank you for your effort

mmmm... not at the moment, I thought it was something everyone woudl like to have but if you think it's not the case I can easily enable this option instead of making it always ON

I guess it's difficult to please everyone... I'm not that keen about the blinking myself.
I'm the guy that also switches off display of seconds when possible...
But I'm sure others will disagree!

papperone wrote: ↑04 Oct 2017, 13:09 so far "beta" plugins has below functionality under testing:
support already both TM1637 (4 digits) and MAX7219 (8 digits) display

both displays have controllable brightness from device page <--------- Is it possible to control this on individual sections or only overall?

2 "modes": CLOCK / MANUAL
- when display is setup as CLOCK it's automatically updated once-a-second
- on TM1637 it shows just hours/minutes with blinking colon (HH:MM)
- on MAX7219 it shows hours/minutes/seconds with blinking segments in-between (HH-MM-SS)
- when display is setup as MANUAL it can only be refreshed manually sending commands
- already implemented "7dn,<number>" will update the display showing <number> (TM1637 range is 0-9999, MAX7219 range is -9999999-99999999)
current bugs/todo (before to release the plugin):
2 or more displays (no matter if same or different model/chip) can't work together connected to the same module - they generates a crash making the ESP8266 unrecoverable if not erasing flash

"7dn" command accepts only integer number; just for MAX7219 decimal dot needs to be enabled as supported by hardware

"7dt" command to be implemented in order to show temperature (TM1637 --> "-XXX" / MAX7219 "-XXX.XX°")
ideas on formats to be used are mote than welcome but please take into consideration hardware limitation!

as temperature can be negative or above 100 (for F°) on TM1637 no decimals nor symbols will be shown

to add support for 74HC595 4 digit modules (tbd)

See my comment above. It would be pretty nice if we could control the brightness in more detail. Great work though!!!

For quite some time, I've been thinking about using espeasy on a Sonoff TH16 to control a fan/heater in our greenhouse. My idea was:

1 x Sonoff TH16 with espeasy. Used as 'logic' plus relay to control 230V to the heater/fan.
1 pcs. temperature sensor (+maybe humidity sensor, just for info)
1 pcs. potentiometer to adjust temperature setpoint
+ now: 1 pcs. TM1637 to show current measured temperature, as well as show setpoint when adjusting via potentiometer.

I'm a bit unsure if this can be done via rules, but it would be very cool

grovkillen · #36 Post by **grovkillen** » 05 Oct 2017, 16:52

I don't see any reason why this couldn't be done with rules.

Great idea of use!

Looking forward to this plugin. Waiting for delivery still though.

I'm still studing the datasheet of TM1637 as I'm not really happy of the library that is available and I'm trying to rebuild communication in the plugin to have it customized and get rid of library; but so far I saw only a general brightness command for all 4 digits. I'll look deeper this evening to check if this request can be implemented in the chip!

papperone · #38 Post by **papperone** » 10 Oct 2017, 10:45

_P073_7DGT plugin submiteed as [TESTING] on the main branch!

Few notes:
- No libraries needed as I coded all the interface with the modules inside the plugin (and customize them on my needs)
- I dropped support of TM74HC595 display as very limited in commands supported and not easy to handle (and I guess it is as well outdated as TM1637 is a much better choice today)
- TM1637 and MAX7219 fully supported
- Modes: Manual, Clock Blink, Clock No Blink, Date
- in Manual mode the plugin reacts to command "7dn,<number>" and "7dt,<temperature>" to show data and it's adaptive (note for TM1637 if you want to use it to show temperature you need to cover the top dot of the colon

)
- other supported commands: "7don", "7doff", "7db,<brightness> (first two very obvious and useful to turn on/off display when not used/needed, last one to setup brightness without accessign ESPEasy GUI)

Please report to me any issues, bugs, features to be implemented, anything, in order to improve the plugin.

NOTE: Still more than one display is not 100% working and can cause crashes of the ESP8266; I will work on this after the plugin will be stable and all functionality fully confirmed working.

ronald · #39 Post by **ronald** » 10 Oct 2017, 11:34

O, that's great! I really want to try it.
I must admit that I don't know how to test it though. I know how to flash my unit and how to upgrade to new versions/ test versions of the software, but I have never added a new plugin.
I can't find how to do it... Can you tell where to find that?

grovkillen · #40 Post by **grovkillen** » 10 Oct 2017, 19:46

Can't wait to try it out! (About 2 weeks until my units arrive.)

Same problem here

I have found the plugin
https://github.com/letscontrolit/ESPEasy/pull/534/files

No idea about the next step , is there a how to plugin wiki ? link?

papperone · #42 Post by **papperone** » 11 Oct 2017, 09:49

I will post BIN later today with dev12 plus this plugin; I will compile only for 4096 module if ok for you....

ronald · #43 Post by **ronald** » 11 Oct 2017, 09:52

Great, Papperone!
4096 is ok for me.

ronald · #45 Post by **ronald** » 11 Oct 2017, 14:22

Hi Papperone
I already tried the device (a TM1637) and for me it is working great!
I tried these modes:
clock blinking
clock not blinking
date
manual command 7dn
7dn,-1000 = ----
7dn,-999 = -999
7dn,9999 = 9999
7dn,99999 = ----
manual command 7dt
- positive number gives me "22:2o" (with the degree symbol in the upper half of course!)
- negative number gives me "-10o"

Display output is working ok.

I would welcome commands to switch the device on or off, like the LCD has.

I tried it on a Witty Cloud version of the esp8266, which is a bit of a pain in the b*t, because so many of the I/O pins are already taken, but my other device were not available.
I hooked it up to D0 (DIO) and D4 (CLK) and that worked.
Thanks for your effort!

Thanks Ronald, probably you should read this previous comment --> http://www.letscontrolit.com/forum/view ... =30#p19744
You have already "7don" "7doff" and "7db,<brightness>" commands implemented...

no idea, I tryed myself to donwload and open it and I got no errors; as well ronald download and installed it without issue it seems...

grovkillen · #50 Post by **grovkillen** » 12 Oct 2017, 19:10

Try 7-zip.

ronald · #51 Post by **ronald** » 12 Oct 2017, 19:38

I used the free utility UnRAR. Worked like a charm.

papperone · #52 Post by **papperone** » 12 Oct 2017, 20:38

I have WinRAR full license and it works as I wrote...

Will dot matrix displays powered by MAX7216 be supported? Just curious.

it's in my "to-do" list but probably as a separate plugin as this matrix led can be more flexible and customizable

Guys,

Sorry for the stupid questions....

How do you know how to connect the display ?

Is there a how-to page where I can find how to compile a plugin into easyesp ?
I have the tm1638 ,would that work as well? At least the display?

p.s.
with the zip7 I managed to unpack. THanks !

I guess not as plugin has been written using the TM1637 datasheet for the implementation.
I don't have a TM1638 handy but looking at google it seems a fair different module with 8 digits, 8 buttons and 8 LEDs...

Hey Papperone

First, many thanks for your great work here!!

Do you know, is there a wiki or good place to start to get a plugin compiled in EspEasy ?

I have seen the developers wiki , but nothing on Plugin's

Somehow I can't get started.

Again, many thanks for your work here

Frank

grovkillen · #61 Post by **grovkillen** » 17 Oct 2017, 13:52

I will make a wiki that is a simplified version of the development wiki.

If you need this plugin only you can find the BIN of 2.0.0dev12 with P073 attached in one of my previous posts.
About how to complie plugins, if you are familiar with Arduino IDE or PlatformIO it's just a matter to copy the file into the main folder of ESPEasy source files and open it from there in order to complie (assumign you have all the libraries with the right version installed of course

)

grovkillen · #64 Post by **grovkillen** » 17 Oct 2017, 21:26

I just added a section to the official Platformio wiki.

https://www.letscontrolit.com/wiki/inde ... ed_plugins

Not alot but essentially its not that much different from compiling the official FW.

ronald · #66 Post by **ronald** » 17 Nov 2017, 19:59

I'm trying to get the temperature from a sensor that's on the same ESP.
I have never used rules before, just don't know how to get them working.
Anyway, I tried and did this:
- Switch the TM1637 to manual mode
- The Temparature sensor is called 'TempPres'
- I switched on rules and created this rule: on TempPres#Temperature do 7dt,[TempPres#Temperature]
- Does nothing....

When I send a http command it works fine, so obviously there is something wrong. But what? Who can tell me how to do it. And can it be done anyway?
I could send the value I get from Domoticz back to the esp, but I hope to get it done with rules this time.

grovkillen · #69 Post by **grovkillen** » 18 Nov 2017, 08:09

Seems correct. What does the log look like? Does it trigger at all?

ronald · #70 Post by **ronald** » 18 Nov 2017, 08:31

No, nothing happens. The display stays dark. When I send a command by http it works.

grovkillen · #71 Post by **grovkillen** » 18 Nov 2017, 08:34

Try this rule:

Code: Select all

On TempPres#Temperature do
 7dt,[TempPres#Temperature]
EndOn

Your code should work but just as a test.

And please send a log file screenshot for us to see.

ronald · #72 Post by **ronald** » 18 Nov 2017, 12:14

It works!!!
The EndOn must have been the problem.
Or maybe the style of coding.
Anyway, it works now and I'm very glad it does.
Thank you for your help!

Great Job grovkillen!
As far as I've one running since more than a month without issue I woudl consider to move this to NORMAL instead of TESTING but I'd like to have at least some confirmation of stability from other users who maybe using it permanently on their devices...

grovkillen · #76 Post by **grovkillen** » 03 Dec 2017, 00:03

Papperone, thanks!!

I've been using it for a day now

I do miss some log output though. And as I asked on GitHub, is the 4 digit display with dots also supported or is it only the "clock" version?

Let me know which LOG and I'll add them and will evaluate to move to NORMAL plugins...
As per GitHub discussion I will add more displays support to the next release of the plugin (once they will arrive from China

)

When I add numbers manually the log is not populated with this. Commands 7don, 7doff and 7db,<value> are not reported. Just that stuff

Ah ok, that's simple... I normally use logs only during developping/testing then I remove them to optimize but you are right, you can always change logs level/reporting from the advanced settings

I will add it soon and submit a PR
