Just an SSR. I use a 10A SSR to control a 2A load and it has no heat issues, but depending on how much power you're going to push through it you might need a heatsink on it or some sort of cooling. Just hook the RCA jack to the input of the SSR, run one 110V wire directly to the plug and the other through the SSD.

I used a double outlet and cut the strip between them on the switched side so I could have one always-on jack and one switched. Instead of a C14 receptacle I just cut the end off the power cord and wired it in directly. Don't be crazy and use 20A parts, standard service is 15A and that's plenty and makes it a bit easier to work with the wire.

Im finally getting around to this. Will this SSR work?

And are people using pumps to circulate water? I was thinkin about using this: http://www.amazon.com/exec/obidos/ASIN/B007XHZ25G/tvwb-20. Can I hook this up to the SSR as well?

Not sure about the pump, but the SSR is OK, I think I ordered the same one, should be here Thursday. Using it to control a Bradley electric smoker that my mom uses.

Edited: actually this is the one I bought

Hi,

I've not had the chance to look at the relay, but from experience I wouldn't bother with the pump.

I started off with one but after it broke (cheap ebay buy) I haven't noticed any difference without.

The linkmeter works perfectly as a sous-vide controller. I probably use it for this as much as for its original purpose!
 
I assume that it does not matter if the ssr is hooked up to a sous-vide or a electric smoker, I will ask here. What should the settings be on the hm for a ssr, to work correctly?
 
If you're using an SSR, then you just set the blower output to 0%-100% and that's all there is to it. (In the future you're also going to want to set "pulse" for the output mode, but that's not until the next version)
 
I have been using my heatermeter controlled crock-pot to re-heat my vacuum packed leftover bbq.

It has been fantastic.
 
Ssr?

I am looking at building a somewhat generic controller that works well for my BBQ pit and on a counter for a sous vide bath. It looks like a few people have the heatermeter working as a sous vide controller and tapping into the pwm signal for the fan. Has anyone modded the board to include a diode suppressed SSR to power a fused 110v/15A receptacle?

OK, finally had time to try some PID tuning on the SSR Heatermeter setup. I switched to Celsius at the same time (a bit easier for the natives I show it to here in Germany). My setup is a 2kw electric smoker element in a Landmann 11091 smoker.

First I got stable oscillation around a 70C setpoint, with P=30, B=8.

Then I tweaked it to B=8, P=14, I=0.12, D=30.​

With those settings I got a pretty stable result with low overshoot and no steady state error when changing setpoint. I haven't tried it at higher temps yet, but it works waaay better than the default values (which are fine tuned for a fan-on-charcoal setup and not SSR).

These values worked better for me as well. Thanks for posting.
 
Any update on the solid state relays and how they have been working. I would like to order one just want to make sure I get one that works well with the heater meter.
