Is anyone on here running TVHeadend on a Raspberry Pi?

If you wish to combine your NAS and Tvheadend server, then transcoding may be significant. And I misspoke: the 4.9 kernel became official at the end of last week.

Decisions, decisions - really not sure what to do now.

I am not going to be needing to do any transcoding, so that can be taken out of the mix.

Ultimately, therefore, it is going to be whether the XU4 really can do everything that my current server is being used for - Openmedivault, TVHeadend and perhaps Emby.

Do you really want a NAS with an ARM SOC?

ARM SOCs are good for clients (if you want a cheap box that lasts only one or two years), for a server i would tend to a x86 base. The XU4 is not that far from a celeron NUC or a beebox with case and shipping costs. If you use WOL or your NAS is not online 24/7, than it's not a big deal if your NAS has a wattage of 5W or 10W, but I think especially for OMV and TVHeadend a NUC is worth the extra charge

Very fair point - I agree that I should stick to x86 for the server.

Here is my current server spec:

G1840
MSI B85M-E45
12GB RAM (2x4GB and 2x2GB)
1 x 64GB Crucial M4 SSD
2 x 2TB Samsung F4 Harddrives
1 x 6TB WD Red Harddrive
HVR-2200 twin DVB-T tuner (PCI-e)
KWorld single DVB-T tuner (PCI)
Superflower Golden Green 350w PSU
Tower with 1 x 140mm exhaust fan and 1 x 120mm intake fan (both fans thermo-regulated).

I bought myself a wattage tester and decided to do some testing.

I took out all the fans, took out the twin tuner and swapped all three hard drives for two spare laptop hard drives that I had lying around.

To my surprise, at idle, the server still uses 32.6W, which is way more than I would like and too much just to leave on all the time.

My remaining options are therefore:

1. Use a C2 purely for TVHeadend and use WOL on the server for recordings or

2. Use an x86 system (like a NUC), which has a much lower idle wattage and can therefore be left running all the time. Is there any point trying to swap out any of the parts from my current server in an attempt to try and get the wattage down to around the 10-15w idle mark or is that going to be impossible?

I was thinking about a recent generation mini-itx motherboard with passive integrated CPU and perhaps a Pico PSU.

Perhaps a bit expensive for a complete box

The cheapest Intel NUC is about 120, in combination with cheap SSD and RAM you are under 199 and have hardware from Intel (with a working UEFI, ...). Even if you assembly your own PC, you would end up in the same range (or below that price if you can reuse parts from another system), but have more options for future upgrades
40 case
100 mainboard + DC
30 RAM
30 SSD

IMHO The point of a storage device is not to have a whole lot of external devices plugged in via usb or esata. Nucs are useless from that point of view, as are most small form factor devices.

Frankly a x86 box with lots of sata ports and space for plenty of disks will be perfect for your data and as a tvh or mythtv backend.

myth can sleep your computer when not recording or serving.

The more I discuss this with you guys, the more I am starting to come full circle on this.

Perhaps there is absolutely nothing wrong with my server as it is. I am even starting to think that I should forget the two HDHomeruns and just put in a TBS Quad DVB-T2 tuner instead - keeping everything in a single box for simplicity.

I have done a few calculations and leaving the server on 24/7 is going to be around the £50-£60 per year in electricity. Not the end of the world but it does slightly irritate me that my server is going to spend around 50% idling unnecessary - someone on the TVHeadend forum is offering some help on getting the server to go into sleep mode after idling for a certain period of time. However, sleep timers and Linux seem like a very complex issues, compared to when I was using Windows on my server.

Not to go off topic too much but how does MythTV compare to TVHeadend? Is there a plugin that allows the server to wake up for recordings?

to turn your circle further: my setup, perhaps it fits your needs

I have an OMV NAS similiar to your old components. Matter of expense is 0€ only old components were used. Wattage doesn't matter, most of the time it's powered off and if another system needs it, it wakes the NAS by WOL.

In my living room I have an enigma2 linux dual dvb-s2 receiver (but dvb-c and dvb-t2 are also available). Features like standby after or wake up for a recording work out of the box, no complex configuration (compared to a htpc) needed. I have paid 70€ for it and inserted an unused hdd for local recordings (but direct recordings to a NAS are also possible)

In other rooms I have clients (pi, S905X and intel) that connect to the NAS and to the receiver with KODI and its PVR client. Access to EPG, recordings and NAS work out of the box, no additional receiver or tv-card needed and an ARM-client costs under 50€

Only disadvantage is that channel switching lasts about 2 sec on the clients, only in the living room where the receiver is connected to the TV its fast as usual. And I would lose a lot of WAF, if the VU+ PVR client is no longer maintained

If you can live with a few quirks, such a setup is possible for under 200€. Otherwise you should plan with 100€ or 200€ more

Mythtv is far superior to TVH.

As I said, mythtv will work to sleep and wake up for recordings. No need for a plugin.
