I’ve just flashed emonSD-07Nov16 RELEASE on my Rasperry Pi 2.

I would like to integrate [homie-ota](https://github.com/jpmens/homie-ota) a OTA “server” for Homie-ESP8266 framework for ESP8266 modules , I tried to follow the [install step by step instructions](https://github.com/jpmens/homie-ota/blob/master/INSTALL.md) but checking the log with

`journalctl -f -u homie-ota@hota`

I obtain this output

```
    Dec 08 21:26:12 emonpi python[810]: IOError: [Errno 30] Read-only file system: '/home/hota/homie-ota/homie-ota/homie-ota.log'
    Dec 08 21:26:12 emonpi systemd[1]: homie-ota@hota.service: main process exited, code=exited, status=1/FAILURE
    Dec 08 21:26:12 emonpi systemd[1]: Unit homie-ota@hota.service entered failed state.

```

the “Read-only file system” on the first line :…I think the problem is due to the fact that the system user hota is trying to write in the readonly partition.  
Thank you

you will need to move `/home/hota/` to `/home/pi/data/hota/` then symlink to allow homie to write to the log file.

`/home/pi/data/ ` is mounted as a R/W partition on the emonPi. Alternatively, you could move the logfile to `/var/log/`

Hi Glyn  
thank you for replying.

I’m sure I’m doing something wrong (I’m sorry but I have a very little experience with Linux).  
I’ve moved  
`sudo mv home/hota/ home/pi/data/hota`

then Rebooted.

Now no more read only error 🙂  
but ☹ it fails

```
Dec 09 09:48:35 emonpi systemd[1]: Starting Homie OTA...
Dec 09 09:48:35 emonpi systemd[1]: Started Homie OTA.
Dec 09 09:48:37 emonpi systemd[1]: homie-ota@hota.service: main process exited, code=exited, status=2/INVALIDARGUMENT
Dec 09 09:48:37 emonpi systemd[1]: Unit homie-ota@hota.service entered failed state

```

and the status is

```
pi@emonpi(ro):~$ sudo systemctl status homie-ota@hota
            ● homie-ota@hota.service - Homie OTA
               Loaded: loaded (/lib/systemd/system/homie-ota@hota.service; enabled)
               Active: failed (Result: exit-code) since Fri 2016-12-09 09:48:37 UTC; 1min 42s ago

             Main PID: 811 (code=exited, status=2)

```

at the same time MQTT server connection refused (from homie-ota.log):  
`2016-12-09 11:22:12,518 ERROR Cannot connect to MQTT broker at localhost:1883: [Errno 111] Connection refused`

But if I manually start the service with  
`sudo systemctl start homie-ota@hota`  
It’s ok, infact checking the status the output is

```
pi@emonpi(ro):~$ sudo systemctl status homie-ota@hota
