Let's Control It

dbemowsk

I have a number of sonoff basic modules that I have been running for a number of years. They are running a super old version of ESP Easy firmware. Not sure what version. Out of the 8 I have had running I have only had issues with 2 of them. I have 2 each in my light/ceiling fan setups. I recently re...

dbemowsk

Out of curiosity, why would it reboot?

dbemowsk

So I wanted to share this trick I did to solve an issue I had. I wanted to control my 3D printer setups through Octoprint using a Sonoff S31 plug with ESPEasy firmware. In searching for some kind of Plugin to control the PSU of my printer, I noticed that there were plugins for many different types o...

dbemowsk

You had asked earlier what build I was running.

dbemowsk

So would I call it like this:

V=voltage
I=current
P=power

http://[IP_of_unit]/control?cmd=secalibrate,V,I,P

dbemowsk

Thank you. I will look that over and figure it out. Any ideas on a good resistive load to use?

dbemowsk

OK, so it appears that the U Ref value keeps changing every so often. You can see here that it is now a negative number. The other numbers stay constant as the I Ref sand P Ref at 16345 and 5362 respectively have not changed from the last screenshots I sent. Only the U Ref has changed. https://dan.b...

dbemowsk

Ok, so I cleared those values and saved. This is the values it showed immediately after the save. https://dan.bemowski.info/wp-content/uploads/2023/08/sonoff_s31_clear_1.png After I close out to the devices list and go back to editing the device again, the U Ref stays the same, but the I Ref and P R...

dbemowsk

So I just flashed a Sonoff S31 with ESP Easy. When I initally configured the CSE7766 power monitor and was checking the values returned, it was showing around 119 volts. Now the voltage being shown is over 900 volts. Do I have something configured wrong that it is showing that high of a value for vo...

I switched to using all asyncevents and it seems to be working. The only time I could maybe see it being any kind of issue may be if there were a rapid press of keys on the keypad in direct succession, but in large part, that shouldn't happen. I'll see how it goes with it this way and if I experienc...

dbemowsk

So this appears to work fine. Is this what you were referring to? On keypad#ScanCode=17 Do asyncevent,"ChangeSwitch=5,0" Endon On keypad#ScanCode=18 Do asyncevent,"ChangeSwitch=5,1" Endon On keypad#ScanCode=33 Do asyncevent,"ChangeSwitch=4,0" Endon On keypad#ScanCode=34...

dbemowsk

The use of event was from the rules code suggestion from Ath. Is it just a matter of putting asyncevent instead of event? If that's all it is I will do it right now. Are event and asyncevent handled the same?

dbemowsk

So here is my updated rule code that appears to work, for the most part. On keypad#ScanCode=17 Do event,"ChangeSwitch=5,0" Endon On keypad#ScanCode=18 Do event,"ChangeSwitch=5,1" Endon On keypad#ScanCode=33 Do event,"ChangeSwitch=4,0" Endon On keypad#ScanCode=34 Do even...

dbemowsk

TD-er Thanks for all the input on this. The logic between the switch and the relay should be the same. I have the switch working with the relay so that when you press the on or off button for a row it changes the state of the LED and also sends the signal to the relay to turn it on or off. The state...

dbemowsk

So just a little update on the progress. Since I needed to get a state sent to Home Assistant to indicate the on/off switch states for each row, and since I was using the LEDs as a visual indicator, I set the 4 LEDs up as devices tied to the GPIO pin they are connected to. I configured my MQTT contr...

dbemowsk

OK, I played with it a bit and got it figured out. That does change the rules code quite a bit and makes it shorter and more compact. Thank you for all your help. Here is the prototype of the new controller. https://dan.bemowski.info/wp-content/uploads/2023/07/new_switch_controller_side_by_side.png ...

dbemowsk

Ath, This is amazing, and a game changer. I didn't know that ESPEasy had point to point UDP communication, much less how to utilize it. I do not have unit numbers configured, but that is now something that I am going to put in my spreadsheet where I am keeping track of the devices I am setting up al...

dbemowsk

Thank you, that worked. I found out I had selected the wrong fimware version, but once I was in I was able to do an OTA update to the correct one.

Thank you again

dbemowsk

So I have a positive update on my progress with this. I have my keypad connected to the PCF8574, which is then connected to the ESP32-C3 board via I2C on address 0x20. The keypad is a 4x2 matrix. I set the SCL and SDA pins under the hardware tab to be GPIO 6 and 7 respectively. I also have GPIO 6 an...

dbemowsk

So I flashed an ESP32-C3 module. After flashing I went to the page where you select your WiFi network and enter your password. I think I entered the wrong password for the WiFi and now it will not connect. When I try to re-flash it, all that happens it the flash tool's console window just show a ser...

dbemowsk

I think I got this. I found the github page for the keypad code. https://github.com/letscontrolit/ESPEasy/blob/mega/src/_P061_KeyPad.ino It shows this which I think is mostly what I need. // Connecting KeyPad matrix to PCF8574 chip: // row 0 = GND (optional if 5 rows needed) // row 1 = P0 // row 2 =...

dbemowsk

So the PCF8574P chips arrived today. Is there some sort of schematic for wiring these to the keypad and an ESP device for use with ESPEasy?

dbemowsk

I will do that. I found out how easy it was to do OTA updates, so switching to the energy build sounds easy enough.

dbemowsk

I wasn't necessarily thinking of connecting any other sensors, I was just wondering really if using the climate build over one of the others would maybe prevent the relays on the R3 from working normally.

dbemowsk

So what functionality does the climate build give you?

dbemowsk

As I was looking into this, I noticed that I mistakenly bought the lite versons of these which don't have the energy monitoring on them. They will only do the switching. The next ones I buy I will make sure have that.

dbemowsk

Sorry for the double post. I didn't realize it submitted twice.

dbemowsk

So I flashed a Sonoff DualR3 tonight with the ESP_Easy_mega_20230623_climate_ESP32_4M316k.factory.bin firmware. I didn't realize it had climate in the name and after booting it and looking at my WiFi network, I was expecting to see some kind of SSID with ESP in the name and I didn't. I saw one named...

I ordered a pack of 5 PCF8574P chips that should be here Saturday. I will give them a shot this weekend.

dbemowsk

TD-er, When I did this with my MySensors setup using an arduino Pro Mini, there is an actual library for the arduinos. The library accepts row and column inputs which are the 2 contacts of any of the switches. The way I understand it works is that it sends a scrolling scan signal over the row pins a...

dbemowsk

Thanks for all that information. I think I am going to get me a couple of these to try out.

dbemowsk

I purchased 3 of the Seed Studio ones to try out. They are 18mm x 22mm so very small. I was able to get ESPEasy flashed to one for testing. I currently just have a basic resistor/LED connevted to test MQTT, and it works really well. On many of the other ESP32 modules, the antenna is integrated onto ...

dbemowsk

I my current light/ceiling fan setups I have 2 sonoff basics mounted in each and I am looking to switch them to a dual relay that I can have ESPEasy on.

dbemowsk

So I was doing some searching in the forum to see if I could find anything on flashing the newer sonoff dual R3. Has anyone done it with one of these yet? Is this even possible? https://www.amazon.com/Sonoff-Metering-Certified-DualR3-Assistant/dp/B091HYC35J/ref=sr_1_2?keywords=sonoff+dualr3&qid=...

dbemowsk

I see you mentioned the MCP23017 again. You mention that it is supported by ESPEasy, but to that end, the PCF8574 is also supported. As mentioned though, space, ease of build and price are factors. Not saying that the MCP23017 is expensive, but it's use gets iffy based on it's size if used in a DIP ...

dbemowsk

Ath, Thanks for the reply, I was looking at some of those options, but I don't need support for 72 buttons. I am only using 8. As for the LEDs I only need 4.The PCF8574 MIGHT be an option, but I would want it to be a minimalist design. That's why I was thinking of the resistor matrix as a possible o...

dbemowsk

I am working on creating some scene controller switches that basically use a 2x4matrix keypad with 4 LEDs and am wondering what the easiest/cheapest approach for this would be. The microcontroller I plan on using is the Seed Studio ESP32 C3 board. For the keypad I thought of creating a resistor netw...

dbemowsk

Thanks for the response. The current way I am using the switches I have is that when I push a button on the switch, that communicates down to my Vera Home Controller in the basement, and then the Vera sends the command to the light/fan to turn on or off. I do find it pretty amazing that that whole p...

dbemowsk

OK, I feel so dumb right now. The 192.168.4.100 address was the IP address of my phone while connected to the AP. THe IP of the AP was 192.168.4.1. Once I put that in the browser, I got to the config page.

dbemowsk

Thank you, I'll give that a try.

dbemowsk

So I used PlatformIO to compile and upload ESPEasy-mega-20230409. It compiles and uploads fine. When I plug in the Sonoff, it goes into AP mode as I can see the ESP Easy AP with my phone. I can also connect using the default password espconfig (or whatever that was). My phone shows that I am connect...

dbemowsk

So my automation setup is kind of a mix of things which are all run through an old Vera Plus home controller. I have light switches that I built that run off of the MySensors framework: https://forum.mysensors.org/topic/4317/us-decora-style-wall-switch/28?_=1682822740637 I am wondering if I can conv...

dbemowsk

I had emailed this workaround solution to this user. Just posting it here for others to take advantage of. I may have a workaround for you that should get you what you need. It relies on a feature of the ESP Easy firmware called "Rules" which is basically a small scripting engine for the f...

dbemowsk

I may have missed it looking through the comments, but is the relay on this on the same GPIO port as the standard sonoff modules? GPIO 12? I see GPIO 14, 4 and 5 on the headers, but not sure what the relay is.

dbemowsk

I posted this on another topic too, so I hope I am not overstepping bounds by posting it here too, but here is a solution that I developed for using ESP Easy with Vera.
