Emulate FB10 for 2nd heating circuit

[vtamac]

Hi Everyone,

My current setup is as follows:

• Junkers ZSB 22-3 C 23
• FW 200 controller
• Gateway S3 from bbqkees

My building is a three-floor house (basement, living floor 1, living floor 2) with the boiler in the basement and the FW200 in the living room of floor 1. Each floor has its own underfloor heating circuit, but unfortunately, only a single FW200 is available to measure temperature and control the boiler and its single circulation pump. I am adding three more pumps for the three floors, and I have a bunch (10+) of temperature sensors across all floors integrated into Home Assistant.

Since the FW200 only supports two types of remote sensors, FB10 and FB100, both of which are discontinued, I believe my only option would be to emulate two (or three, and move the FW200 to the boiler) FB10(0) sensors. This way, the FW200 can remain the master thermostat, able to read desired/current temperatures from the remote ones and control the boiler accordingly.

Is it possible to solve this with the Gateway S3, even if it requires additional hardware? I noticed the menu "Custom Entities," but the documentation is pretty much empty about that.

I am open to any other additional ideas. Of course, the reason for the suggested approach above is to keep the FW200 with all its intelligence (some sort of PID controller inside, I guess). Let me know if a more convenient way exists.

Thank you,
Tamás

We can try, i've seen a log with a remote FB10 (product-id 109, ver 16.5) on hc1, sending direct to master with type-id 0x0123. For other hc is it unclear if they use the same telegram from different devices (like RC20 remotes) or different telegrams from different devices (like RC100H) We have to test. I'll prepare something in my testbuild.

Still no new device on ESP UI, but FW200 tells that "there is new remote controller on the network please adjust settings".

Ok, next try, now the reply to requests should work with ht3. Please log a few minutes more.

log is attached. Device now shows up on the UI and picks up the temp sent in log (3).txt

[MichaelDvP]

But it seems the FW200 does not set the roomtemp. Changed to 0x123 again, as seen in #773.
The incomplete telegrams seems, that sometimes the break is missed after polling the remote, but very random. What TX-mode do you use?

[MichaelDvP]

Please update again and test.

[vtamac]

FB10 shows up again. Log is attached. log (5).txt

Also, should I set anything on my FW200 I normally do not change anything on it during tests

[MichaelDvP]

I thought you have already 2 heatingcircuits.
Sure the heating needs hardware for each circuit: a pump and a control for the pump, this is the IPM module. Without that you cant realize a heatingcircuit.

[vtamac]

Sorry for the misunderstanding! Unfortunately, You can't buy these modules anymore (IPM, FB10). I might be able to solve my issues with 1 heating circuit - at least there will be one which FW200 knows about and I can control the emulated FB100 via home assistant and update it with the values of the circuit which requires more heat (where the desired and actual temp diff is the biggest).
If going with 1 circuit and one FB10 what are the next steps required?

1. Is your branch going to be merged into the main so that I can upload the new releases too (if any)?
2. What's the process of this FB10 emulation to remain permanent? If the ESMESP board reboots I have to call this function again?

Thank you,
Tamás

[vtamac]

Actually, even with 1 HC the FW200 shows an error about a missing bus component (FB10).

Please find the log attach

[MichaelDvP]

Seems to be the same as in #1611, maybe sending more often helps, i've changed in my test build.

I think IPM are sometimes on ebay, but you also need a pump and change the piping to split the heatingcircuit. That's a lot of work to do.
