Hi,

I have homegear running with pimatic as frontend. Everything was working until the last update to Homegear version 0.7.9-1375.

I have updated from 1.6 to 2.5 firmware with my HM-ES-PMSw1-Pl. The Devices are listed in peers list with the new version 2.5

Manually switching the 5|6|7 is working and homegear broadcasts the state.
But for some reason calling setValue with id 7 fails with ‘Device not found’

10/03/17 21:14:15.435 RPC Server (Port 2001): Info: Client number 12 is calling RPC method: setValue (4) Parameters:
(Integer) 7
(Integer) 1
(String) STATE
(Boolean) 0

{
  [faultCode]
  {
    (Integer) -2
  }
  [faultString]
  {
    (String) Device not found.
  }
}

Has something fundamentally changed?

Anyone? I think this is an enormous problem since a fresh install to a clean debian armbian system leads to the same result.

auth: none

Using this { "jsonrpc": "2.0", "id": 125, "method": "getValue", "params": [5,2,'STATE']}

Prints the following error in the log:
10/08/17 14:10:32.309 RPC Server (Port 2001): Info: Connection from ::ffff:192.168.100.110:49170 accepted. Client number: 12

Edit

Ok using double quotes for String leads to the initial “Device not found” error.

I do not understand why no one else has this problem.

Using integerValue64 result in 0, but 1 was given.

10/09/17 18:38:42.751 RPC Server (Port 2001): Info: Client number 9 is calling RPC method: getValue (3) Parameters:
(Integer) 1
(Integer) 2
(String) STATE
INT:   1
INT64: 0

This was changed from 0.7.8 -> 0.7.9 so it seems to be the problem here.

Found the issue.

libhomegear-base/src/Variable.h is missing the integerValue64 assignment in the uint8_t constructor.

Hey @pheinrich,

you are not the only one who reported the problem. I would have looked into it tomorrow. So I was surprised to see the solution in your pull request on GitHub. Great job!

Cheers,

Sathya
