API http://[IP]/api/thermostat/info gives error

[RikBast]

I tried to use http://[IP]/api/thermostat/info in v3.7.1 and it gives an error:

{"message":"unknown device thermostat"}

In v3.6.5 it gives the correct response.

[proddy]

support info?

[RikBast]

support info?

Sorry for the late response in this.

What happens is the following under v3.7.1:

When I typ: http://192.168.0.50/api/thermostat into any browser window I now get this response:

{"message":"unknown device thermostat"}

This used to be in v3.6.5

{"hc1 Streeftemperatuur kamer (seltemp)":15.0,"hc1 Huidige kamertemperatuur (currtemp)":16.4,"hc1 Discovery huidige kamertemperatuur (haclimate)":"kamertemperatuur"}

It's also reflected in my LUA code with a Fibaro Home Center 3 where I use the 'GET' function

function QuickApp:httpGetJsonThermostat(url, body, func)
  self.http:request(url, { 
  
      options = {

can you send your system info please? https://docs.emsesp.org/Support/

[RikBast]

can you send your system info please? https://docs.emsesp.org/Support/

I have a Gateway E32 (Ethernet + WiFi Edition) from BBQKees, is that what you need? Bought in jan 2023. I contacted BBQKees already and he suggested to open an issue here at GitHub

[MichaelDvP]

For the system info navigate to http://192.168.0.50/help and download the support information, attach it here.
Or call http://192.168.0.50/api/system/info and copy the output.

After update and restart it takes around minute to find the devices on the bus, in this time you will get the unknown device message.

[RikBast]

Here is system info:

Still the same error:

{"message":"unknown device thermostat"}

[proddy]

that's very strange, I can't think of what could cause that. Do any of the other API calls work, like api/boiler or api/system ? And if you go to the Telnet console and do a su with ems-esp-neo and then call thermostat info does it work?

[RikBast]

boiler info is returning values:

function QuickApp:startGetBoilerInfo()
  self:httpGetJsonBoiler("http://192.168.0.50/api/boiler/info","",processResult)
  --self:checkState()
  --self:startGetThermostatInfo()
end

With telnet I will try later today.

[proddy]

@MichaelDvP any idea what could cause this?

[MichaelDvP]

I've already mentioned:

After update and restart it takes around minute to find the devices on the bus, in this time you will get the unknown device message.

But only get back: "uptimeSec":46, with "api":{"APICalls":2,"APIFails":1} indicating the api fail was before.
How often should i mention to wait longer?

[proddy]

please test and re-open (with support info) if you still have issues.

[RikBast]

http://192.168.0.50/api/thermostat still gives this message:

{"message":"unknown device thermostat"}

[proddy]

Oh!

[MichaelDvP]

Oh, this is an easy thermostat, not writeable, so if fails here:

EMS-ESP32/src/command.cpp

Line 68 in 473cf7c

if (!device_has_commands(device_type)) {

This is a bug.

[RikBast]

Glad you found the issue, thank you for helping

[proddy]

good find Michael

[MichaelDvP]

@RikBast Please check with the new dev version if it is fixed.

[RikBast]

@MichaelDvP Works! Thank you
