Hello,

how does the watchdog functionality work exactly? I can't seem to find any documentation about watchdog. And how can I Get and Change the watchdog state? I looked in the evok 1.11 API (https://evok-14.api-docs.io/1.11/rest/get-watchdog-state-watchdog-alias)

The following get requests give me an internal server error 500:

("GET", "/rest/wd/1_01", payload)
("GET", "/rest/watchdog/1_01", payload)
("GET", "/rest/wd/1", payload)
("GET", "/rest/watchdog/1", payload)
("GET", "/rest/wd/1/1", payload)
("GET", "/rest/watchdog/1/1", payload)

whilst input, ai and ouput do work.

What am I missing? Does the Unipi 1.1 even have a watchdog?

Thank you for the answer!

I am using the websocket API now, as this suits my requirements the most.

Have a nice day!

Hello!

I'm new to the Unipi. I have Python and general coding/programming experience.

I have the Unipi 1.1 and a RaspberryPi 3B+. I want to create an application to monitor the rpm of a machine, and if the rpm is ok, i output a signal on a relay.

For this, i need to read analog and digital inputs and write relay states. I started to play a bit with the Evok API and i ran into following problem:

1: command line: curl http://localhost:8080/json/input/{1,2} - works
2: command line: curl http://localhost:8080/json/{input,ai}/{{1,2},1} - works
3: python: conn.request("GET", "/json/input/1", payload) - works
4: python: conn.request("GET", "/json/input/{1}", payload) - does not work
5: python: conn.request("GET", "/json/input/{1,2}", payload) - does not work
6: python: conn.request("GET", "/json/input/%7B1%7D", payload) - does not work

Output of #2:

Output of #4-#6:

b'{"status": "error", "message": "Internal Server Error", "code": 500}'

Python-code:

import http.client

conn = http.client.HTTPConnection("localhost:8080")

payload = "{}"

conn.request("GET", "/json/input/%7B1%7D", payload)

res = conn.getresponse()
data = res.read()

print(data)

maybe the problem is, how the http.client.request method handles the URL. but i already tried to Encode the URL, and it didnt help...

What can i try now?

Best Regards
