Yeah, I think that was a senior moment. I clicked on the link. Then I copied the mqtt_as.py, saved it both on my pc and the microcontroller. Now, How to incorporate that into my script....? Don't answer that just yet, I'm thinking out loud. If you don't hear from me for a week or two, then, I may ne...

I and Kevin Köck developed mqtt_as. This does support multiple subscriptions. Please excuse my ignorance. But, is mqtt_as a module? I am using Thonny. How do I get mqtt_as onto my microcontroller as part of Micropython? Does that just import on THAT microcontroller and I have to import it on every ...

I'm pretty sure I don't have to re-write to the entire screen just to update the temp data. How would I go about keeping the top line "Playroom" and just refresh the temperature? Ideally, I shouldn't need to update the temp as frequently as I have here. Probably every 15 minutes would be more realis...

Peter; Thank you so very much. That was what I was looking for. Without my Wifi login, here's the final script. I just got in an OLED display that plugs right on top of the ESP8266. Header pins soldered, a little bit of fiddling to get the code just right... Came out pretty nice. ###################...

Everything is working well. BUT, Id like to learn how to format the decimal places when "publishing" to MQTT. Or should I worry about that on the subscribing/working end? As in my sensor script, (with help) I got it to display the temp with just one decimal space in the REPL 87.7 But, when it publis...

Hmmmm.

Another option is to have one topic and signal your intent with different messages.

You mean something like?:
Topic = Relay

Messages =

• Relay1OFF
  Relay1ON
  Relay2ON
  Relay2OFF

I would then need 4 "IF msg==:" statements?

To show you how it was done using Arduino IDE: Once subscribed to both topics, then activate each Relay separately. // ******************* RELAY 1 ***************************** if (strcmp(topic, "Relay1") == 0) { for (int i = 0; i < length; i++) { char receivedChar = (char)payload[i]; if (receivedCh...

When I do that, it says it's subscribed to Relay2. Maybe I did it right with this and it's only saying subscribed to relay2 but actually subscribing to both? client.subscribe("Relay1"), ("Relay2") I was too focused on just the REPL and not the outcome when run, sending messages to the MQTT server. I...

I'm struggling. I'm going to keep at it until I get there! Here's my code so far: # *****ASSIGN VARIABLES*****************# # RELAY 1 rel1 = machine.Pin(05, machine.Pin.OUT) # ASSIGN OBJECT NAME TO GPIO PIN 05(D1), OBJECT IS AN OUTPUT. rel1(0) # TURN OFF RELAY AT STARTUP topic = "Relay1" # MQTT TOPI...
