      You may have to make a slight mod to the board or enclosure to make it fit.
      good luck

    • RE: Multiple BME280 sensor for Domoticz

      Thanks for the reply and spotting one of my many errors (now corrected amongst others!).
      Managed to get one of them showing up in Domoticz, lets see if i can get them both in there without the temp hum being crossed over between physical sensors. There seems to be a few posts about this problem.

    • 2 or more DHT22 on 1 node with Domoticz

      I wonder if any one can help with my (hacked and borrowed) sketch that inlcudes x2 DHT22 sensors on one node. Before I start I think my problem is the way Domoticz handles the data so this post probably shouldn't even be on here.
      My sketch below works in the Mysensors serial monitor and i even have a version with a TFT lcd display, all correct. The problem is when it appears in domoticz the humidity from one sensor appears on the other and the 2nd hum is ignored.... for a few seconds it then randomly appears on the correct sensor. There seems to be a few posts problems but with no solution. Can anyone help?

    • RE: Why are the measured values so different? Are my humidity sensors faulty?

      @benhub do you have the code the links seem dead? Ive been trying to get 2 temp/hum sensors (DHT22) working in domoticz for quite a while now with no luck. The temp/hum data in domotcz keeps swapping around from one sensor to the other and i cant work out why.

    • Multiple BME280 sensor for Domoticz

      Hi,
      I'm trying to build a node that uses x2 BME280 sensors for a whole house fan controller, one inside temp/hum and one outside. The BME280 has a selectable I2C address by grounding the SDO pin on the sensor. I have successfully tested this using the BlueDot_BME280.h library and sketches.
      Problem I am having is turning this sketch into a working Mysensors node I can use in domoticz. I think I'm almost there but cannot see why i am getting an 'invalid use of non-static member function' message.
      here is my hacked code...

      I thought i would try and get it working with one BME280 first..

    • Clock Sketch (RTC) modified for 1.8" LCD

      Just embarking on making the 'Real Time Clock Module, LCD Display and Controller Time' sketch to use with a 1.8" lcd 128x160 ST7735. Problem i have is trying to get it to display the correct format of time.
      eg I would like to display:-
      06:03:09 instead of 6: 3: 9 for the time and equivelant for the date too. This is a problem when the numbers reach double figures as you get false times because it doenst clear.

      I think i need to use something similar to this;

      if (digits < 10)
      myGLCD.printNumI('0');

      I am using the UTFT libraires but cannot work out the correct syntax.
      the pic below is not a great example as the time when i took this was all double digit numbers the date and month are single. but need it to say 06/01/20

      UTFT clock (2).jpg
      below is my code

      /**
         The MySensors Arduino library handles the wireless radio link and protocol
         between your home built sensors/actuators and HA controller of choice.
         The sensors forms a self healing radio network with optional repeaters. Each
         repeater and gateway builds a routing tables in EEPROM which keeps track of the
         network topology allowing messages to be routed to nodes.

    • RE: Multiple DHT22 in one sensor for greenhouse (newbee question)

      Is there a way i could display the temp and hum for each sensor on an lcd screen?

      below is my sketch that flips between 2 sensors on the LCD

    • RE: Anyone help with 4 relays please?

      Ah ok, good to know. I also spoke too soon....
      Today they were unstable, I noticed that some of the on /off commands were not being recieved (small LED flash on the arduino) looked at the logs on domoricz they were fine, however the serial monitor on the arduino node confirmed they weren't always being seen.
      Have changed the mysensors libraries on the node to be the same as the usb gateway and its all stable again.
      next action will be to monitor the logs on the gateway, node and domoticz at the same time

      I have one of those blue 4 relay units from ebay, the jumper has been removed so only the LED lights when i activate the channel.
