Could you be more specific what ‘problem’ you encountered while compiling the firmware?

Setup the VM box to run Linux makes a lot of problems… looks like the resources from my computer are not enough.

This is really interesting!
I have problema to compile the firmware. Can somebody provide a already compiled firmware with MQTT?

[Kunstflieger]

Is there someone else who can help me with this?

Hello Ray,
thanks for this help! I have a PCF8574 at home and connected it to an ESP8266. But I couldnt switch any relays which are connected on the PCF. Attached I have the picture, how it is connected. What I´m doing wrong?

Hello,

if OpenSprinkler will also subscribe MQTT topics, it would be a nice feature to subscribe an external rainsensor status. Correct me if I´m wrong, but as I know the rainsensor can only connected via hard wiring.

The example from @digitalbits is pretty cool! And I want to expand the example for sensor 1 and 2 (since FW 2.1.9)

sensor updates (weather, flow, and rain)
mqtt-topic : osprink/sensor/weather
mqtt-payload: {“type”:”sensor”,”id”:0,”name”:”weather”,”data”:{“action”:”update”,”adjpct”:38,”ts”:1530391894}}

Example could be:
mqtt-topic : osprink/sensor/1/status
mqtt-payload: {“type”:”sensor”,”id”:1,”name”:”Rainsensor”,”data”:{“action”:”update”,”status”:”closed”,”ts”:1530391894}} –> or status:”open”

mqtt-topic : osprink/sensor/2/status
mqtt-payload: {“type”:”switch”,”id”:2,”name”:”Programstart”,”data”:{“action”:”update”,”status”:”open”,”ts”:1530391894}} –> or status:”closed”

Best Regards

Hello,

I see that some of you tried to run the hardware with a NodeMCU which is based on ESP8266. Mmaybe someone can help me with my questions.
I´ve compiled the code which is on a NodeMCU v3 now.

But I do not know, how the outputs are connected to the esp8266. Is there a shiftregister (74HC595) like for the OSPi?
Also how is the rainsensor connected?

Best Regards
Kunstflieger

Thanks for this great point! I just have a question. How should I compile it for raspberry pi?
Would it also work if I copy all the content from https://github.com/OpenSprinkler/OpenSprinkler-Firmware to my own github account and change the OpenSprinkler.cpp there?

Thanks for your help, Ray.
I just decided to use transistors 2n3904 as shown in this picture

Hi Alevog,
I´m looking for an alternative for BT1308 and found this Thread.
Could you find the issue on your problem? Where the MAC97 the right Triacs?

[Kunstflieger]

Thanks for this answer. This is correct. I use this off-the-shelf relay modul.
Is it possible to change this in the source code on the OSPI?

[Kunstflieger]

Hello Ray,
is there a new manual refers to webhooks? I couln´t find it.

Thanks
Kunstflieger

Jisse154

do you have it also as compiled .bin file?
And how the relais are connected to the NodeMCU? Is it with a shiftregister?

[Kunstflieger]

Is it also possible to connect the rain sensor direct on GPIO 14? Is a Pull-UP or Pull-Down required? I didn´t found documents for this.
