Pimatic mit ESP8266 - NodeMCU oder ESP-01

---

Hallo zusammen,

ich schreibe in diesem Forum da ich im deutschen Forum leider kein Thema eröffnen konnte.
Vielleicht kann man das Thema verschieben? Ich kann Englisch einigermaßen lesen, aber leider keinen solchen Text in Englisch formulieren. Und nach dem Google Übersetzer wollte ich den Inhalt keinem mehr antun.

Ich beschäftige mich seit 4 Wochen mit Rpi und seit 3 Wochen nun auch mit Pimatic. Ich möchte mit Pimatic auf RPi 3b+ meine Terrarien Regeln welche sich in verschiedenen Räumen und Etagen befinden. Bei meinem ersten Tarrarium habe ich nun alles direkt am RPi angeschlossen Und steuere diverse Beleuchtung, Lüfter, Pumpe, Ultraschallvernebler und Begegnungsanlage via 433MHz Funksteckdosen nach Messwerten welche ich mit DHT22, DHT 2302 sowie BME/P 280 (I2C) Sensoren erhebe.
Soweit funktioniert das auch schon ganz gut, etwas fein Tuning ist noch notwendig, aber im großen und ganzen bin ich schon sehr zufrieden und freue mich das ich mit meinem bescheidenen bis nicht vorhandenen Linux- und Programmierkenntnissen durch Pimatic all meine Wünsche umsetzen konnte.

Nun möchte ich jedoch als nächstes ein weiteres Terrarium auf der anderen Seite der Wohnung verbinden. Vorgestellt hab ich mir das ganze via ESP8266, hierzu habe ich aktuell 2 NodeMCU zur Verfügung (einmal v3 und einmal v2) sowie einen ESP-01. Nach einiger Recherchen habe ich die bereits ca. 3 Jahre alten Möglichkeiten ESPimatic sowie ESPEasy gefunden, und mich nun einige Tage mit ESPimatic beschäftigt.
Leider bekomme ich die Software via Arduino DIE (auch in der empfohlenen Programmversion) nicht aufs NodeMCU hochgeladen. Hierbei bekomme ich immer diesen Fehler: „base64_encode’ was not declared in this scope“ welchen ich leider nicht beheben konnte.

Daher nun die Frage: Gibt es aktuellere Möglichkeiten meine vorhandene Hardware via WLAN mit Pimatic zu verbinden? Oder hat jemand eine Idee wie ich den vorhandenen Fehler korrigieren kann?

Viele Grüße
Alexander

Hello everybody,

I write in this forum because I could not open a topic in the German forum unfortunately.
Maybe you can move the topic? I can read some English, but unfortunately I can’t formulate such a text in English. And after the Google translator I didn’t want to do the content to anyone anymore.

I have been working with Rpi for 4 weeks now and with Pimatic for 3 weeks now. I want to use Pimatic on RPi 3b+ to create my terrarium rules which are located in different rooms and floors. With my first tarrarium I now have everything connected directly to the RPi and control various lighting, fan, pump, ultrasonic nebuliser and encounter system via 433MHz radio sockets according to measured values which I raise with DHT22, DHT 2302 as well as BME/P 280 (I2C) sensors.
So far it works quite well, some fine tuning is still necessary, but on the whole I am very satisfied and happy that I could realize all my wishes with my modest to non-existent Linux and programming knowledge through Pimatic.

But now I want to connect another terrarium on the other side of the apartment. I imagined the whole thing via ESP8266, I currently have 2 NodeMCU available (once v3 and once v2) and an ESP-01. After some research I found the already 3 years old possibilities ESPimatic and ESPEasy, and now some days I am occupied with ESPimatic.
Unfortunately I don’t get the software via Arduino DIE (also in the recommended program version) uploaded to the NodeMCU. Here I always get this error: “base64_encode’ was not declared in this scope” which I could not fix.

So now the question: Are there more current possibilities to connect my existing hardware to Pimatic via WLAN? Or does anyone have an idea how I can correct the existing error?

Many greetings
Alexander

Hello, a very good possibility is flashing with tasmota. And then to connect the ESP via mqtt with pimatic.
From tasmota you can download the required data for ArduinoIDE or also as *.bin. The *.bin can be easily downloaded to the ESPs via NodeMCUflasher.

About mqtt there are also instructions in german.

@OrTiNG
Thanks for the translation, if a translator meets the requirements here I handle it exactly the same way .

@Thrusty
Thanks for the tip. I’ll take a look. I’ve already heard a few things from mqtt, so I obviously have to deal with it. For the communication between ESP and Pimatic the plugin mqtt for Pimatic is used, I suppose?

Translated with www.DeepL.com/Translator

@azrael
Here you can find some information about the plugin: pimatic-mqtt.
In this forum you will also find a lot about it. And surely also help.

Tasmota has become very versatile and powerful in the meantime. And there are now a lot of devices supported. And if you have the time to wait, with AliExpress they are often very cheap.
A friend built his whole SmartHome with “tasmota - devices” and a Raspberry.

@Thrusty

Thanks, I’ll finally get to read something tomorrow.
I think I will understand the connection between Tasmota and MQTT then .
As I understand it so far I need a MQTT Broker which collects the data or gets it sent. I think it runs via the plugin. It sends this data to all devices that want to receive it. At this point Pimatic has to be there again.

@Azrael
The broker (mosquito) is the server that receives and distributes everything. It can be installed besides pimatic on the raspberry (localhost). But it can also run on another system (e.g. NAS, second raspberry). The pimatic plugin works as client, as well as the tasmota devices.

On the sonoff/tasmota website go to “Configuration”. Then click on “Configure mqtt”. Here you can enter the IP of your mosquitto at Host.

Port 1883 is default. Below you can see the topic.

On the first page there is a button “Console”. Here tasmota shows you all messages you want to see. Here it also shows you the Topic’s you need.

In pimatic it looks like this:

In the mqtt plugin settings of pimatic the IP of mosquitto must be set. And a restart of pimatic is then necessary.

Hello, everyone,

@Thrusty

Thanks a lot! That was exactly what I was missing. I didn’t know how important the names were in the MQTT. Therefore my sensors were not recognized.

Maybe you can help me with how I can now use the NodeMCU via MQTT to send a 433MHz transmitter of this kind https://www.amazon.de/gp/product/B071J2Z3YK/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
Can I talk to this one to be able to switch various radio sockets away from the RPi?

@azrael
I’m afraid I’m out of it. But there are some projects with NodeMCU or Wemos and mqtt.
Zb here

On the other hand, if your distance from the RPi to the RF sockets isn’t too great, why do you want to take the detour via mqtt? You could use the pimatic homeduino plugin.

I have Homeduino transmitting up to about 10m. Through a few walls and a ceiling. My roller shutters open and close regularly. Quite rarely the time a signal gets lost. The disadvantage is that there is no feedback at 433mHz. You have to live with it.

Here is a very good description of @leader21.

Thanks, I’ll take a look at that article.
Currently I have connected a 433MHz transmitter directly to the RPi via breakout board. This controls a terrarium in my living room.
I have another terrarium on the completely other side of the apartment (5 walls and about 20 meters away). There I installed now an ESP which gives me the temperature data of the terrarium and the environment. But also at this terrarium one or the other would have to be switched, this would have to run via WLAN, therefore the NodeMCU.
Furthermore I have a 3rd terrarium in my basement, which I would like to measure and control via NodeMCU as well. In addition to the 5 walls and 20 meters there are 3 floors (ceiling).

Homeduino I must also still look at, with this I would like to replace the Breakout Board. But this is further back on the ToDo list. This has less to do with necessity than with appearance and comfort .

@azrael
Why don’t you work with a relay board directly on NodeMCU. They come with one, two, four, and more relays. This would give you a safe feedback.
Or do you want to build a “Wifi extension” with Rf 433mHz?
A Wemos as a repeater would also be a possibility.
There is also another ESP, e.g. ESP8266-01. The Wemos or NodeMCU has the advantage that the periphery is already given. You can power them directly with a USB cable.

@Thrusty
I didn’t want to use the relay board because I have to connect 230V completely and I don’t think these relays without housing are completely harmless, especially if there are children in the house.
There is the possibility to switch radio sockets per 433MHz but the safer one. Since all live parts are then also cleanly processed.

What do you mean with a repeater via Wemos? So single stations with 433MHz receiver and transmitter to carry the signal? I think this is very susceptible to interference, or have you had other experiences?
I found the power supply of the NodeMCU via Micro USB quite good. They provide enough power for the sensors and the 433MHz transmitters. I wanted to solder it all and install it in a surface mounted junction box.

The MQTT sensor query of the 3 nodes is spinning around since this morning and I can’t do anything with the error. At the same time Pimatic shows the following error:

error [pimatic]: Error loading device “nmcu3”: (@plugin.brokers[@config.brokerId])
error [pimatic]: Error loading device “nmcu2”: (@plugin.brokers[@config.brokerId])
error [pimatic]: Error loading device “nmcu1-temp-tiefland”: (@plugin.brokers[@config.brokerId])

A restart of Mosquitto, Pimatic and finally the whole Pi didn’t make any difference.
The error occurred at 11:27 this morning. The last 2 days, however, no changes were made at the configuration.

@azrael
The one with the 230V is of course true. You have to tinker a little bit more to pack it safely.

The one with the repeaters is actually not quite right. Strictly speaking you can also call it a router (NAT). But I’m still testing it myself. It doesn’t really work yet, not as I thought.

And your error, I can only google such things. But take a look at this maybe it helps. Or maybe this. I had a similar mistake once, or the same mistake!? 🤔

At the start of pimatic i also used a lot of 433 mhz divices, but they arent realy reliable, so i only use esp divices now with ESPEasy.

Here you can find some infos, maybe it helps:
https://forum.pimatic.org/topic/1367/espeasy-with-pimatic-over-mqtt

Habe früher auch nur 433 mhz Geräte benutzt, allerdings kann man sich nie sicher sein, ob diese auch wirklich schalten. Deswegen nutze ich auch nur noch ESPEasy.

That’s what I’m talking about.

Sorry the last days I missed the time for the project. Now I want to go on

@4nubis
How do you switch your devices with ESPEasy? I’ve flashed a NodeMCU with it but I’m quite unaware how I can switch the devices better than with Tasmota.
433MHz doesn’t seem to be possible with it either. What is the alternative in this case? Also with relay?

@Thrusty
You switch your devices completely with relays despite less “protection”?

Translated with www.DeepL.com/Translator

Sorry die letzten Tage hat mir leider die Zeit für das Projekt gefehlt. Nun soll es dann mal weitergehen

@4nubis
Wie schaltest Du Deine Geräte mit ESPEasy? Ich hab nun mal eine NodeMCU damit geflasht bin aber doch recht Ahnungslos wie ich damit die Geräte besser schalten kann als mit Tasmota.
433MHz scheint auch damit nicht ohne weiteres möglich zu sein. Wie ist in dem Fall die Alternative? Auch mit Relais?

@Thrusty
Du schaltest Deine Geräte trotz weniger “Schutz” komplett mit Relais?

@azrael
I only have one ESP-01 with an open relay, both in a box.

Otherwise I use any Sonoff Pow‘s, Sonoff Basic‘s and Sonoff 4CH‘s. The first two are already closed. The 4CH’s sits on a DIN rail, in the switch box.
And a Shelly, there is in a flush-mounted box.

Which one of you still uses ESP Easy? I don’t get any sensor data from DHT22 on my ESP Easy flashed NodeMCU.
The structure of the NodeMCU is the same as the previously flashed Tasmota.
The sensor is configured to D3 (GPIO-0), but does not display any data under Devices. Does anyone have an idea what this could be?

Wer von euch nutzt denn noch ESP Easy? Ich bekomme auf meinem ESP Easy geflashten NodeMCU keine Sensordaten vom DHT22 abgefragt.
Der Aufbau des NodeMCU ist gleich geblieben zu dem vorher geflashten Tasmota.
Der Sensor ist auf D3 (GPIO-0) konfiguriert, Zeigt aber unter Devices keine Daten an. Hat jemand eine Idee an was das liegen kann?
