Relays and ioBroker

[DieterB61]

Hi,

after successfully logging my data using an ESP32 board, I ordered a board with 4 relays to realize power control using the X85 connector. Unfortunately I got a board with ESP-12F (ESP8266). As I got my money back without having to return the board I gave it a try to use it for ESPAltherma.

To see if everything is working, I first flashed Tasmota and could set all 4 relays from ioBroker using the Sonoff-MQTT-Adapter. The ioBroker MQTT Adapter did not give me all possibilities! For configuration see https://templates.blakadder.com/ESP12F_Relay_X4.html

Then I flashed ESPAltherma using the nodemcuv2 environement.
In a first attempt I tried to set the relais using the SG Pins. I set:
#define PIN_SG1 16// Pin connected to dry contact SG 1 relay (normally open)
#define PIN_SG2 14// Pin connected to dry contact SG 2 relay (normally open)
Pin 14 and 16 worked for Tasmota. For RX and TX Pins 4 and 5 where used.

The logging works in this configuration, but I'm not able to change the status of the relays when I change the SG -> Set Value within ioBroker. I've tried SG_RELAY_HIGH_TRIGGER and SG_RELAY_LOW_TRIGGER.

Any idea what I'm doing wrong?

Additional question: has the board to be connected to X10A to test the switching of the SG relais?

Today I tried to add javimurcia X85 extension but I got the same behavior. Relais did nothing when changing ths x85a -> set value.
Here one picture how it looks like in ioBroker MQTT Server (1):

I used now an ESP-32 Board, but although there GPIOs do not change there value when I try to set SG from espaltherma. Thus I'm quite sure that there is a problem with iobroker MQTT and espaltherma.

I found the problem. It was a wrong configuration of the MTTQ Server/Client of ioBroker that let me read the data but not write data. For users of ioBroker: take care to set the mask to publish correct (in my case it had to be mqtt.1.* as I used Adapter 1).

Now my ioBroker works with a 4 relay board with ESP-12F (ESP8266) processor and the X85A extension to set energy levels :-) .

You can see the board here:

I ordered it at joom but it is sold out now:

In fact I got no ESP32 but ESP-12 board which also works using the code available here.
Search for "ESP32 relay board" to find one.

Thank you! I'm mostly new to hardware, this is useful.

Would you be willing to share information about the board you ordered?
