MODBUS with HVAC Pluggit

m.ach · May 23, 2017, 1:05pm

I am running OH1 for a while, thanks for this great project and work which is done here. Now I’m facing a new challange to implement my ventilation unit PLUGGIT AP310 to the OH system. The unit is connected with LAN to the network. I try to do this with the modbus binding, unfortunatly i’m very new to this.

What I plan to do:
read temperatures from the unit
set fan speed (later connected with rules: depending on humidity/presence/etc).

Here is my try:

/////////////////Sitemap
Switch item=FanSpeedValue03 mappings=[0 = “off”, 1 = “1”, 2 = “2”, 3 = “3”, 4 = “4” ]

Can any of the modbus geeks please give me feedback if I can try this approach without damage the device and if this works
Thanks.

Try to test a single register read outside of OH using any modbus master simulation tool.

In OH1 try this simple config:

modbus:poll=1000

modbus:tcp.value01.connection=192.168.6.181:502
modbus:tcp.value01.id=1
modbus:tcp.value01.start=132
modbus:tcp.value01.length=2
modbus:tcp.value01.type=holding
modbus:tcp.value01.valuetype=float32

then check the log.

Note that you will not be able to write (update) 32-bit values in the device over OpenHAB Modbus for the time being. Reading should present no special problem.

m.ach · May 30, 2017, 7:42am

thanks for the feedback.
It went well with the above setup (except that I mixed uint and float values - so the issue with writing float values is not a issue for me, because it’s uint).

But this leads to further question regarding Float-Transformation. The Temperature Values I got are Float32, with CDAB sequence. So for example for Temp T1 I read:
{modbus=“value01:0”} it’s 0
{modbus=“value01:1”} it’s 16768
Is there a trick, without a complex rule to tranform that in a decimal temperture in Degree ?

Thanks.

rossko57 · May 30, 2017, 10:22am

wouldn’t CDAB just need valuetype=float32_swap:in your .cfg file?

Be careful of the 0/1 address offset between “modbus register numbers” and “modbus protocol address” conventions.

m.ach · May 31, 2017, 10:56am

hi rossko, thanks for reply.

I tried “swap” but with no success. Values are still pretty high, and not tranformed to decimal.
tcp.value01.start=132
tcp.value01.length=2

{modbus=“value01:0”} = 60762 (fast changing)
{modbus=“value01:1”} = 16825 (stable)
Do I have to tranform that float values by myself with a complex rule inclduing CDAB?

rossko57 · May 31, 2017, 11:08am

No, you just have to get the configuration right.
A float32 (or float32_swap) is two registers to fetch across Modbus, and then the binding transforms and presents as a single number to an Item.

modbus.cfg

// register 40089
...
tcp.value01.start=88
tcp.value01.length=2
tcp.value01.valuetype=float32_swap

xxx.items

Number TemperatureValue01 "Outdoor T1 Temp [%.1f]" (hvac) {modbus="value01:0"}

There is no value01:1 at all in this simple case

m.ach · June 2, 2017, 12:23pm

hi rossko57, thanks for your help. I did it as you suggested, but I see no the correct Tempertures, What did i wrong?

Output sitemap:

extract from config.cfg: (for register 400133 and 400135)
tcp.value01.connection=192.168.6.181:502

…

rossko57 · June 2, 2017, 7:44pm

Have you tried as float (no swap)?
The manual isn’t very clear about addressing offset; worth trying start=133

I expect you realise you can reduce the config (which needs to go into modbus.cfg not config,cfg)

tcp.value01.connection=192.168.6.181:502
tcp.value01.id=1
tcp.value01.start=132
tcp.value01.length=4
tcp.value01.type=holding
tcp.value01.valuetype=float32_swap



xxx.items   ( not xxx.item)

Number TemperatureValue01 "Outdoor T1 Temp [%.1f]" (hvac) {modbus="value01:0"}
Number TemperatureValue02 "Supply T2 Temp [%.1f]" (hvac) {modbus="value01:1"}

Hello Christian,

I just tried your setup regarding the fanspeed: I does update the register (although it is not quite the correct offset as it should be 325) and the changes are also shown in the Pluggit-App. But the device does not switch the fan speed. I think it’s necessary to update the 32bits in the correct sequence, which is not the case with the openhab modbus binding. But thats just a guess.
Does your device actually switch the fan speed?
By the way: All other values read correct - including current fan speed, temperatures and mode.

ssalonen · September 3, 2017, 5:58pm

You are correct @mf_bib – as mentioned in the documentation, the float32 writing is not working with the openhab1 addon

Note: The way Decimal commands are handled currently means that it is probably not useful to try to use Decimal commands with non-16bit valuetypes.

If you feel lucky, you can try out the experimental/new openhab2 modbus binding. The new version should handle float32 writes correctly.

m.ach · January 8, 2018, 12:55pm

thanks for the reply. I have in fact the described issue with fan speed. Reading is no issue, but writing. The value is updated, even the PLUGGIT Android App shows the new value, but the physical machine is ignoring it.

I updated to OH2 to solve that issue, but with no luck. I recognised that it is not a float32 writing issue, because the value ist UINT according documentation … :-/

modbus:writemultipleregisters=true
modbus:tcp.pluggitfanspeed.connection=192.168.1.11:502
modbus:tcp.pluggitfanspeed.id=1
modbus:tcp.pluggitfanspeed.start=324
modbus:tcp.pluggitfanspeed.length=2
modbus:tcp.pluggitfanspeed.type=holding
modbus:tcp.pluggitfanspeed.valuetype=uint16

Any ideas? I learned from the FHEM guys, that they have a binding for Pluggit, so there it is working.

Thanks for any help.

BerserkerXP · January 23, 2018, 9:11pm

try this settings:

writemultipleregisters=true

Helge_K · February 5, 2018, 6:26pm

According to documentation:

3.3.1 All parameters of the ventilation unit have a 32-bits dimension.

However, reading a 16 Bit value at address 624 is ok, so long I do not write on it.

Since I have a working PHP solution, I’m surprised that it does not work on the Modbus binding

Helge_K · February 10, 2018, 5:01pm

After some experimenting here my working configuration.

The Unix times still having a small problem, the lower digits are not right (Up to 12h, in my case)

Changes to the cfg file have the effect that no more data points can be written. It seems that the main config file are not build correctly. If I delete the main config files
/var/lib/openhab2/config/org/openhab/m%0023 odbus.config
/var/lib/openhab2/config/org/openhab/modbus.config

and do a restart, all is working fine.

Hello Helge!

wow, tnat helped a lot, thank you for the great work!

Writing the values to the device doesn’t work: fan speed and active unit mode. I don’t know if the Pluggut 310 doesn’t accept these values, or if I have to configure something… I’m running OH snapshot 2.3 with the 1.12.0.SNAPSHOT modbus binding. Do you have any idea?

Thanks a lot!

Best regards
Robert

Hi Robert,
have you considered the following

robaer · May 24, 2018, 7:05am

Hi Helge,

yes, I know this issue. The config file is built correctly, and my OH is reading all values correctly (fan speed values, …). But writing doesn’t work, but I cannot set the active unit mode. I was wondering if I have to configure something special, or maybe there is a bug in the binding?

Hello Robert,
I compared the Modbus solution with my PHP solution and noticed that both variants have a different behavior
It seems that the “Active Unit Mode” only works halfway. Although the changes are recognized by the Pluggit App but they are not transferred to the current unit mode register.
It is a bit strange indeed
